1. Which is a source of genetic variation?
a. Mutations
b. artificial selection
C. exponential growth
d. genetic bottlenecking
Answer:
Mutation is a source of genetic variation
Answer:
Mutations
Explanation:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

When a substance changes from a gas into a liquid due to a change in temperature, melting occurs, which is a physical change.
When a substance changes from a solid into a liquid due to an increase in temperature, it is a physical change.
When a substance changes from a gas into a liquid due to a decrease in temperature, the substance cools down and condenses, which is a phase change.
When a substance changes from a liquid into a gas due to a decrease in temperature, the substance evaporates and cools down, which is a phase change.

Which statement best describes the use of a catalyst in a fuel cell? It reduces waste. It lowers energy requirements. It reduces toxic exhaust. It increases reaction rates.
The statement that best describes the use of a catalyst in a fuel cell is : ( D ) It increases reaction rate
A catalyst in a fuel cell speeds up/facilitates the rate of reaction of oxygen and hydrogen especially at the oxygen electrode of the fuel cell.
Generally catalyst is any substance that increases the rate of a chemical reaction without been used up in the process, while lowering the activation energy required to kickoff the reaction.
Hence we can conclude that the statement that best describes the use of a catalyst is that it increases the reaction rate

What is photosynthesis???
By definition, photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.
With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.
Photosynthesis takes place in 2 stages:
In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O₂). The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

what is happening in the convection layer of the Sun
Answer:
In the convective zone, the temperatures are cool enough—under 1,800,000 degrees Fahrenheit (1,000,000 degrees Kelvin)—that the atoms in the plasma there can absorb the photons coming outward from the Sun's radiative zone. The plasma gets very hot, and begins to rise upward out of the Sun.

What factors could decrease the rate of photosynthesis in a plant?
Answer: light intensity, carbon dioxide concentration and temperature i think- maybe
Explanation:
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either
Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?
The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.
CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.
With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.
An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.
In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:
NevadaWestern Utah, Eastern California, andIdaho.But the major part of Nevada is occupied by the Great Basin Desert.

Which of the following best predicts the effect of not having ATP available to supply energy to this
process?
A. H+ ions will stop moving through the protein.
B. H+ ions will move in the other direction through the protein.
C. H+ ions will continue to move through the protein in the original direction but at a slower rate.
D. H+ ions will begin to move through the phospholipid portion of the membrane in the original direction.
H+ ions will stop moving through the protein is the effect of not having ATP
available to supply energy to this process.
ATP is the form of energy used by cells and it ensures that cells perform their
daily activities optimally. ATP is needed in a lot of metabolic reactions and
transportation of materials within cells.
When there is a lack of ATP, it means there is no energy required to
transport or move substances within a cell. This means that the H+ ions will
stop moving through the protein and is the most appropriate choice.
