Answer:
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. ... A force has both magnitude and direction, making it a vector quantity.
Therefore, yes
A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer:
D
Explanation:

When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl CoA. Predict how many ATP can be made from one molecule of acetyl CoA if oxygen is present. Show your work.
Answer: Suppose that each fatty acid in a certain fat can make 9 molecules of acetyl CoA. Predict how many ATP can be made from the fatty acids in this fat. This would make 27 acetyl CoA, and therefore would make 27 ATP

describe the different processes involved in the movement of these substances into and out of the cell; oxygen, carbon dioxide, glucose, potassium, water, and enzymes.
Answer:
Dissolved or gaseous substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread.
Explanation:
To enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.
What is cell?Cell is defined as the fundamental membrane-bound entity that houses the essential molecules of life and is the building block of all living things.
It can also be defined as a semipermeable cell membrane encloses one or more nuclei, cytoplasm, and different organelles, which are the smallest structural component of an organism capable of autonomous functioning.
There are basically two types of cell.
Prokaryotic cellEukaryotic cellCell membrane is defined as a biological membrane that keeps all cells' interiors isolated from the outer world and provides protection for it.\
Barriers and gatekeepers are cell membranes. Because of their semi-permeability, some molecules can diffuse across the lipid bilayer but not others.
Thus, to enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.

r If a mouse population changes color from white to black over many generations, which question should be asked to determine whether the population changes are a result of natural selection or artificial selection?
A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

Name the enzyme that breaks the hydrogen bonds holding the
two DNA strands together during DNA replication?
DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.
What is DNA helicase?During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.
In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.

Which of the following statements describes a process that occurs during photosynthesis but not during cellular respiration?
ATP is produced that stores energy.
O
Chemical energy is converted to light energy.
Reactions occur in the mitochondria of the cell.
Light energy is converted to chemical energy.
Answer:
D (see below for explanation)
Explanation:
Using the process of elimination, we can go down the answer choices:
A) ATP is produced that stores energy.
In photosynthesis, light energy, water, and carbon dioxide is taken in and converted to oxygen and glucose. Cellular respiration, however, uses glucose and oxygen and converts it to water, carbon dioxide, and ATP.
As you can see, there is no mention of ATP in photosynthesis. ATP is not created in photosynthesis—photosynthesis' main purpose is to make food for the organism.
So A is not the answer.
B) Chemical energy is converted to light energy.
In photosynthesis, the light energy taken in is converted to chemical energy so it can be used. Cellular respiration requires only oxygen and glucose, so light energy doesn't relate to cellular respiration directly.
However, if you read the answer carefully, it says that chemical energy is converted to light energy. The main purpose is to use the light energy, which cannot be used in its light form, so it has be converted into chemical energy.
So B is not the answer.
C) Reactions occur in the mitochondria of the cell.
Photosynthesis occurs in the chloroplasts of an organisms. Heterotrophs do not have chloroplasts, so they cannot make their own food. However, mitochondria are in all eukaryotic cells, as cellular respiration occurs in all eukaryotic cells as well.
Cellular respiration happens in the mitochondria of a cell. Photosynthesis does not.
So C is not the answer.
D) Light energy is converted to chemical energy.
If you go back to my explanation for B, you can see that photosynthesis uses light energy, but to do so, it has to convert it to light energy first. It cannot use light energy itself.
So D is the right answer.
