How has the development of a pine and then a hardwood forest affected populations of shrubs?
A The development of the two types of forests has negatively affected populations of shrubs by decreasing the amount of pollinators in the area.
B The development of the two types of forests has positively affected populations of shrubs by increasing the amount of water available to shrubs.
С The development of the two types of forests has negatively affected populations of shrubs by decreasing the amount of space available to shrubs.
D The development of the two types of forests has positively affected populations of shrubs by increasing the amount of sunlight in the area.
Answer: Option C.
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs
Explanation:
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs because pine and hardwood are huge trees bigger than shrubs and occupy space. As they occupy space the received most of the sunlight, their roots is very extensive and draw water and nutrients from the soil which makes these resources not very much available for shrubs and hence it drastically affected the populations of shrubs. Because of their heights, wideness and big leaves, little sunlight gets to shrubs and hence shrubs photosynthesis is reduced.
The removal of one seral stage to another is called ecological succession.
The place which is used by the shrubs is now used by the tree and give the competition for the land. The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs.

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?

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.

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.

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.

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 chemical equations must be balanced. This means that the same number of atoms
of each of the elements must be found in both the reactants and the products of the reaction. Which scientific law does this illustrate?
Law of Reflection
Law of Conservation of Energy
Law of Conservation of Mass
Law of Superposition
Answer:
The Law of Conservation of Mass.
Explanation:
The reasoning behind this is that when the chemical equation is balanced, so is the amount of mass. We make sure that the chemical equation is balanced to ensure that the law of conservation of mass is conserved. This is why we add coefficients to the beginning of reactants and products to make sure that the mass of the reactants combined is the same amount of mass of the products combined.
Answer:
The Law of Conservation of Mass!
