Classification of Living Things Notes
1. An organism is a living thing.
2. Characteristics of all living things:
1) Organisms obtain and use resources. All organisms must obtain resources, such as food and water, which provide required energy to perform the basic processes of life, like growing, developing, and repairing injured parts.
2) Organisms respond to stimuli: A stimulus is any change in an organism’s surroundings that will cause the organism to react. Examples of environmental stimuli include changes in the amount of light present, changes in temperature, sound, amount of water, space, amounts of food present. The reaction to the stimulus is called a response. It can be an action or behavior performed by the organism.
3) Organisms reproduce-produce offspring that have similar characteristics as the parents. Reproduction can occur in one of two ways:
a) Asexual reproduction involves one parent that makes an exact copy of itself. The offspring are identical to the parent.
b) Sexual reproduction involves two parents. Sperm cell from the male and egg cell from the female combine to produce offspring that have characteristics from each parent.
4) Organisms grow and develop. Growth is the process of an organism becoming larger. Development is the process that occurs during the life of an organism that results in the organism becoming more complex. Organisms require energy to grow and develop.
3. Classification is the process that scientist use to arrange organisms into groups based on the shared observable characteristics.
4. Taxonomy is the science of identifying and classifying organisms into groups.
5. A taxonomist is a scientist who identifies and names organisms based on their similarities and differences.
6. Taxonomist use physical characteristics as well as DNA, genetic information, to classify organisms.
7. Scientist all over the world study organisms, in order to avoid confusion scientists need a universal way of naming organisms.
8. A dichotomous key is a tool used to identify organisms. It uses a series of questions, each with only 2 answers.
9. Linnaeus developed a system for classifying organisms called binomial nomenclature. It uses two Latin words to name an organism. The name is made up of the genus and species of the organism. The name is written in italics, the genus is capitalized, and the species is lower case; for example, the scientific name for a human is Homo sapiens.
10. The Linnaeus system is made up of seven levels, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
1) King Philip Could Only Find Green Socks is one mnemonic way to remember the order of the levels. Another is King Philip Came Over For Good Spaghetti.
2) The levels are arranged from the most broad, Kingdom, to the most specific, Species.
11. Kingdom- organisms are placed into kingdoms based on their ability to make food and the number of cells in their body.
12. Phylum (phyla is plural)- In the Plant Kingdom, phyla are sometimes called divisions. In the Animal Kingdom, there are 35 different phyla.
13. Class, Order, Family-these levels become even more specific. Each level has fewer organisms that have more in common with each other as you move down the levels.
14. Genus- contains closely related organisms. The genus is the first word in an organism’s scientific name.
15. Species- consists of all the organisms of the same type which are able to breed and produce young of the same kind. The species is the second word in an organism’s scientific name.
16. Most scientists classify organisms into 5 kingdoms: Plants, Animals, Protists, Fungi, and Monera.
1) Plants (Plantae)- the plant kingdom is made up of plants. Plants are autotrophs, they make their own food. Plants are eukaryotes; they are made up of many cells. Plants are divided into 2 groups: vascular and nonvascular.
2) Animals (Animalia)- the animal kingdom is made up of animals. Animals are heterotrophs- they must obtain food by eating it. Animals are eukaryotes. The 35 phyla are divided into two groups: vertebrates and invertebrates.
3) Fungi- the fungi kingdom is made up of molds, yeasts, and mushrooms. Fungi are heterotrophs because they must absorb their food. Yeasts are one celled, while molds and yeasts are eukaryotes. Their cells have a nucleus, a cell wall, and no chlorophyll. Most fungi are decomposers, they break down dead organisms.
4) Protists (Protista)- the protists are made up of organisms that cannot easily fit into the plant, animal, or fungi kingdoms. They are one celled organisms with a nucleus or simple multicelled organisms. Some protists are autotrophs, some are heterotrophs.
5) Monera- the Monera kingdom is made up of bacteria. Their cells do not contain a nucleus. Some bacteria are autotrophs, some are heterotrophs.
Answer for brainiest :)
Answer:
D
Explanation:
Well, animal cells use simple sugars, like glucose. The simple sugars are the only ones small enough to pass through cell walls. We use ATP to access the energy in the sugars. Cells can either use a aerobic system (using oxygen) or an anaerobic system to metabolize sugars. Humans generally use the aerobic system although in some cases our cells are forced to use the anaerobic system.

Work-Rate Problems
There are two equivalent formulas to choose from when solving work-rate problems. If two people are working together on a job then their work rates add and they can perform the job working together in a shorter amount of time. If we let = the time it takes a person to complete a task then his work rate is 1/. In other words, he can complete the 1 job in number of hours. If we let = the time it takes a second person to complete the task and = the time it takes for both people working together we get the following work-rate formulas:
Example: Bill’s garden hose can fill the pool in 12 hours. His neighbor has a hose that can fill the pool in 15 hours. How long will it take to fill the pool using both hoses?
Example: Joe can complete his yard work in 3 hours by himself. If his son helps it will only take 2 hours working together. How long would the yard work take if his son was working alone?
Example: Norm and Cliff can paint the office in 5 hours working together. Being a professional painter, Norm can paint twice as fast as Cliff. How long would it take Cliff to paint the office by himself?
Work-Rate Problem: One small water hose takes twice as long to fill the basin as the larger water hose. If the two hoses working together take 40 minutes to fill the basin how long would it have taken each hose to individually fill the basin?
Work-Rate Problem: Joe can texture and paint a room in 8 hours working alone. It would take Bill 6 hours to do the same job. How long will it take them to complete the job working together?
Work-Rate Problem: Two printers, working at the same rate, work together with printing payroll checks for 4 hours before one breaks down. The other takes 3 more hours to complete the job working alone. How long would it have taken only one printer to complete the job?
Uniform Motion Problems (Distance Problems)
We have set up uniform motion problems using the formula = *. For the following motion problems, we will need the equivalent formula / = to set up the equations.
Example: The first leg of Mary’s road trip consisted of 120 miles of traffic. When the traffic cleared, she was able to drive twice as fast for 300 miles. If the total trip took 9 hours, then for how much time was she stuck in traffic?
Example: A passenger train can travel 20 miles per hour faster than a freight train. If the passenger train can cover 390 miles at the same time it takes the freight train to cover 270 miles, how fast is each train?
Example: Billy rode his skateboard 24 miles to his grandmother’s house for the day. It was a rough ride so he borrowed his grandmother’s bicycle for the return trip. Going twice as fast on the bicycle the return trip took 2 hours less time. What was his average speed on the bicycle?
Example: Brett lives on the river 45 miles upstream from town. When the current is 2 miles per hour he can row his boat downstream to town for supplies and back in 14 hours. What is his average rowing speed in still water?

Explanation:
What is the mass number when it is stable?
Answer:
The mass number (symbol A, from the German word Atomgewicht [atomic weight]),[1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. Since protons and neutrons are both baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. Hence, the difference between the mass number and the atomic number Z gives the number of neutrons (N) in a given nucleus: N = A − Z.[2]
The mass number is written either after the element name or as a superscript to the left of an element's symbol. For example, the most common isotope of carbon is carbon-12, or 12
C
, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12
6C

The graph illustrates the activity level of three common digestive enzymes, across a range of pH values. Hydrochloric acid is used by the stomach to aid in digestion and causes the stomach to have an average pH of 1.5 to 3.5. Which enzyme is likely to be active in the acidic environment of the stomach?
Answer:
Digestion starts with the sight, thought, or smell of food. When the brain anticipates an incoming meal, the vagus nerve sends a message to the stomach causing the release of acetylcholine. The binding of acetylcholine to G cells in the stomach starts the secretion of gastrin and, in combination with acetylcholine and histamine, stimulates parietal cells in the gastric glands of the stomach body to start secreting hydrochloric acid (HCl).

all compounds are negatively charged, true or false?
Answer:
false
Explanation:
"Electrons are the "material" of the charge that is flowing. Therefore, current can never cause a metal object to become positively or negatively charged, because the net number of electrons in the metal object will never change due to current flow."
Which of the following describes plant cells but not animal cells?
A. The nucleus contains the chromosomes
B. The ribosomes assist in protein synthesis
C. Plastids store starch made during photosynthesis
D. mitochondria produce energy through respiration
Answer:C. Plastids store starch made during photosynthesis
The statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Animal cells do not perform photosynthesis so they do not have plastids. Plastid is a type of cell organelle which is specific to only plant cells that significantly store starch that is synthesized during the process of photosynthesis.
Animal cells have cell organelles like mitochondria, endoplasmic reticulum, etc. while chloroplast and plastids are specific to plant cells.
Therefore, the statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.

C. The cell membrane contains proteins and lipids, but not carbohydrates.
D. A phospholipid bilayer forms the semipermeable cell membrane.
I hope that this helps you!
The correct statements that describe the structure of cell membrane are:
Proteins, lipids, and carbohydrates are found in and on the cell membrane.A phospholipid bilayer forms the semipermeable cell membrane.The plasma membrane or cell membrane of organisms is made up of a bilayer of phospholipids in which proteins, carbohydrates, glycoproteins, and glycolipids are embedded. In animal cells, there is cholesterol too.
The biological membranes of cells are made up of two layers of phospholipid. Each layer contains a lipid tail attached to a polar head. The head is polar in nature directed both outward toward the environment of the cell and inward toward the cytosol.
In this way, a hydrophobic region of lipid tails separates the solution into two parts. That makes it a semipermeable membrane.

Rabbits normally eat some grass as a food source. In a habitat, a new species of grass is introduced that out-competes most of the original species of grass. The new species of grass contains a chemical that is usually toxic and fatal to most rabbits. Assuming that all rabbits in this habitat will eat some of the new species of grass, how will the presence of the new grass most likely decrease the diversity of the rabbit population in this habitat?
Answer:
Well The Diversity will decrease.
Explanation:
If the Grass Is Toxic to the Rabbit than the rabbits will either die from eating the grass, or they will stop eating it and need to find a new food source. this will lead to the to the rabbits that are resistant to the toxic grass being able to reproduce more and therefor becoming more abundant.

Will the CO2 molecules that exist today still be the CO2 molecules in a million years
Answer:
Yes
Explanation:
cause nothing is created or lost it is just cycled.
Yes, the carbon dioxide molecules existing today will be the same carbon dioxide molecules in a million years because the matter is not created or destroyed.
What is carbon dioxide?
Carbon dioxide (CO2) is a colorless gas with a sour taste and a little harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
It is produced during the combustion of carbon-containing materials, fermentation, and animal respiration, as well as during the photosynthesis of carbohydrates by plants.
The so-called greenhouse effect is caused by the gas because its presence in the atmosphere prevents part of the radiant energy that Earth receives from being reflected back into space.
In the industrial setting, it is recovered for a wide range of uses from flue gases, by-products of the hydrogen-preparation process for ammonia synthesis, lime kilns, and other sources.
Therefore, the same carbon dioxide will exist in a million years as today.
