What happens to the rate of most reactions as the reaction progresses? (3 points)
The rate change depends on the energy change of the reaction.
The rate decreases as the concentration of the reactants decreases.
The rate increases as the concentration of the products increases.
The rate remains constant over the course of the reaction.
Question 4
3 pts
Answer:The rate decreases as the concentration of the reactants decreases.
Normally in a chemical reactions, reactants react with the product to form reactants. The continuous availability of the reactants ensure constant formation of the products, thus the reaction continues to progress.
However, after a period of time,of reaction progress, the rate of reaction drops.This is because, the concentration of reactants has been used up, and therefore more product is formed.Thus the concentration of both the reactants and product changes; and this slows down the rate of reaction as the concentration of the reactants drops.
Explanation:
Answer:
The rate decreases as the concentration of the reactants decreases.

Which of the following provides the best summary of the process of natural
selection?
A. Individuals always change in response to their environment.
B. Genes are passed from parent to offspring.
c. Mutations always increase an individual's fitness.
D. Individuals that are well adapted to their environment survive.
Answer:
D. Individuals that are well adapted to their environment survive.
Explanation:
The correct answer is individuals that are well adapted to their environment survive.
How do individuals adapt to their environment?
We can acclimatize to a wide range of temperature and humidity. When traveling to high altitudes, our bodies adjust so that our cells still receive sufficient oxygen.
Why do the individuals that are best adapted to the environment survive?
The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

How is the solubility of most genes and solids in water affected by the temperature of the water?
Answer:
in higher temperatures the molecules will increase however in colder temperatures the molecules will decreasing and eventually melt. (more info below)
Explanation:
if the water is hot, the average kinetic energy of its molecules will increase. As a consequence, the solution is capable of extracting additional ions from the surface of the solute. As a result, temperature increases the solubility of substances. Sugar and salt, for example, are more soluble in water at higher temperatures.When the temperature of the solution changes, the total kinetic energy of the molecules that make up the solution often decreases.The enhanced friction (kinetic energy) of the molecules of the solute allows them to be less able to stay on and therefore melt more quickly.

Which of the following best explains the difference between micro and macro evolution? A. Microevolution is based on ideas, while macroevolution is based on facts B. Both micro and macro evolution are when you witness changes to a gene pool. C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation. D. Macroevolution is small scale change to the gene pool of a population while microevolution is larger scale changes that lead to speciation.
Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.

Interpret: Directional selection occurs when individuals at one end of a range are more likely to survive than intermediate individuals or individuals at the opposite end of the range. Stabilizing selection occurs when intermediate individuals are the most likely to survive.
Is directional selection, stabilizing selection, or both operating in this example? Explain.
Answers:
Stabilizing selection occurs when intermediate individuals are the most likely to survive.
Explanation:
Both because for example the birds with larger beaks could survive the drought and after 2 years stabilizing selection also occurs.
Answers:
Directional selection occurs when individuals with traits on one side of mean in their population survive or reproduce more than those on the other.
Hope it helps you.
Answer:
I believe both directional and stabilizing selection are operating in this example since only the large-beaked finches were able to survive the drought while the smallest-beaked finches disappeared. But also, we need to highlight after the second year stabilizing selection occurred because finches with large beak depth were the most likely to survive than those with smaller beaks, that is why that specific type of beak became more common.

Explanation:
Plant shoots exhibit positive phototropism by growing towards the light, while their roots exhibit negative phototropism by growing away from light. The hormone auxin directs this process. Auxin increases in concentration on the side of the shoots and the roots that faces away from the light. Auxin has different effects in each of these locations.
What is the best explanation of how auxin directs phototropism in plant shoots?
Answer:
Auxin increases in concentration on the side of the shoots and the roots that faces away from the light.
Explanation:
Auxin is a growth hormone in plants.it is promotes elongation of roots and shoots. It is very sensitive to light. when the plant is exposed to light, the auxin in the exposed part of the shoots breaks down. And diffuses to the shady part not exposed to light..
The higher concentration of auxin at this parts, promotes accelerated growth, which caused the part to bend to of this shoot to grow faster than the other part, and bends towards light.
While the roots grows towards.
