Answer:
True
Explanation:
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).
true or false: plants release energy as ATP during cell respiration and use it for maintenance and growth
Answer: The outcome of cellular respiration is that the plant takes in glucose and oxygen, gives out carbon dioxide and water and releases energy. Plants respire at all times of the day and night because their cells need a constant energy source to stay alive.
Explanation:
A population of rabbits moves to a dry desert environment. How could natural selection be a main contributing factor to speciation in this rabbit population?
A) Most of the rabbits die due to dehydration.
B) Some rabbits reproduce at a different rate.
C) The rabbits are able to interbreed with other species of hare living in the desert.
D) Some of the rabbits are better adapted to the drier environment.
Answer:
D) Some of the rabbits are better adapted to the drier environment.
Explanation:
Natural selection is when the environment favours certain traits in organisms. Organisms that possess these traits are more likely to survive and pass on the traits to their offspring, leading to evolution.
Speciation is when populations become different enough (for example due to natural selection acting on variation in the population) that new species form.
If some rabbits posses traits that make them better adapted to the drier environment, then these rabbits are more likely to survive and pass on these traits to their babies. Eventually, this can cause speciation, as the rabbits that live in the desert are subject to different selective pressures (drier environment)
How long ago do scientists believe the continents formed Pangaea?
about 135 million years ago
about 180 million years ago
about 300 million years ago
about 4.5 billion years ago
The scientists believe the continents formed Pangaea about 300 million years ago. The correct option is C.
What is Pangaea?According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's external crust glided over the inner layers until they consolidated as a landmass encircled by a huge ocean called Panthalassa.
After a while, the Angaran continent near the North Pole began to move south and combined with the northern part of the expanding Euramerican continent, forming the Pangea supercontinent. This process was completed approximately 300 million years ago.
Alfred Wegener observed the same thing in 1912 and proposed that the continents were once scaled down into a single protocontinent known as Pangaea.
Thus, the correct option is C.

Using the weather data in Table 1, create a 12-hour general weather forecast for the next day following the data collected.
Questions and Conclusion
1. Write a summary of the weather that occurred during the 24 hours in Table 1.
2. What are the possible sources of error in the weather data?
3. What relationships do you notice between temperature, dew point, humidity, cloud cover, and air pressure? Provide evidence for these relationships from data in Table 1.
4. In conclusion, how did your graphs support or contradict your 12-hour forecast for the following day?
5. Describe additional data you could collect to make your forecast more reliable.
6. What did you learn about weather forecasting by completing the activity(optional to answer, but an idea for something to write as a response would help)
Explanation:
1. During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures.However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space. Therefore, less of the sun's energy is able to reach the earth's surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.When forecasting daytime temperatures, if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.At night cloud cover has the opposite effect. If skies are clear, heat emitted from the earth's surface freely escapes into space, resulting in colder temperatures.However, if clouds are present, some of the heat emitted from the earth's surface is trapped by the clouds and reemitted back towards the earth. As a result, temperatures decrease more slowly than if the skies were clear.When forecasting nighttime temperatures, if cloudy skies are expected, forecast warmer temperatures than you would predict if clear skies were expected.
2. The possible sources of error are human error and misreading the data.
3, As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. High relative humidity of the air occurs when the air temperature approaches the dew point value.
4. When forecasting if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.
5. A more reliable approach to weather forecasting is known as the steady-state or trend method. This method is based on the knowledge that weather conditions are strongly influenced by the movement of air masses that often can be charted quite accurately.
6. Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?
A)The atoms form a bond with a bond length of 25 pm
B)The atoms form a bond with a bond length of 75 pm
с)The net force between the atoms is attractive at 25 pm
D)The net force between the atoms is attractive at 75 pm
Answer:
A)The atoms form a bond with a bond length of 75 pm
Explanation:
The Morse curve is a plot of potential energy against internuclear distance between two atoms.
When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.
The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.
For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.

Hi guys does anyone have notes for lesson characteristics and classification of living organisms? Also I need some questions so that I can be prepared for the test
Answer:
Explanation:
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.

Testosterone is a small steroid hormone that is important in cell signaling. Which of the following indicates where testosterone enters a cell and why it is able to cross at that point?
А
1, because testosterone is nonpolar and can diffuse through the membrane.
B
2, because testosterone covalently binds to a surface protein and transports into the cell.
C3, because testosterone dissolves in water and flows through the channel
D
4, because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis.
<
Answer:
A
Explanation:
explanation is given in answer
Testosterone is a steroid hormone. It is a primary sex hormone. It plays key role in the development of male reproductive tissues such as testes and prostate.
Testosterone is lipophilic signaling molecule. The plasma membrane consist of lipid bilayer so testosterone diffuse through the lipid bilayer and enters the cell.
So, the answer is option A because testosterone is nonpolar and can diffuse through the membrane.
other options-
B because testosterone covalently binds to a surface protein and transports into the cell- incorrect. Testosterone doesn't binds to a surface protein and transports into the cell, it diffuses through the cell membrane.
C because testosterone dissolves in water and flows through the channel-incorrect. Testosterone is nonpolar.
D because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis-incorrect. Testosterone is not filtered out of the extracellular fluid and it is not taken into the cell by endocytosis.
