are all cells going through the cell cycle at the same speed? why or why not?
Answers
Answer: Not all cells move through the cell cycle at the same rate. Proteins that regulate the timing of the cell cycle. Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms.

Which of the following is not an appropriate unit for momentum?
A. g • cm/min
B. g • m/S
C. km • m/S
D. kg • m/hr
Answers
Answer:
Option C us correct.
km • m/S
Explanation:
This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.
From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

Which of the choices below would determine if a protein will perform a specific function for the cell?
A.The monosaccharides that make up the protein
B. The nucleic acids that make up the protein
C. The shape of the protein
D. The fatty acids that make up the protein
Answers
Answer: C
Explanation:
The folding of the protein determines the structure. Each polypeptide has a primary structure all the way up to quartenary structure which allows the protein to fold based on the R groups of the amino acids. If the structure of the protein is disturbed, it won't perform its proper function.
The image, in which A represents a gene, shows a harmless mutation that has occurred in a species' genome. Which is the most
plausible way that this mutation may eventually benefit the species?
A)
Multiple copies of genes increase gene expression and protein synthesis,
improving fitness
B) One copy of the gene may mutate further and begin to function differently
from the original.
C) Individuals with different copy numbers of the gene will not be able to
mate, resulting in speciation.
D) Individuals with the mutation are not able to produce offspring and will be removed from the gene pool.
Answers
Answer:B
Explanation: I took this test
One copy of the gene may mutate further and begin to function differently from the original is the most plausible way that this mutation may eventually benefit the species.
What is Mutation?A mutation is a change to an organism's Genetic sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells constantly undergo mutations, yet surprisingly few of these have an adverse impact on our health. A mutation is never so advantageous in real life.
Therefore, One copy of the gene may mutate further and begin to function differently from the original is the most plausible way that this mutation may eventually benefit the species.

According to Darwin's theory of evolution, what causes a struggle for survival in
populations?
Answers
Answer:
In a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).

how would you describe a phospholipid?
Answers
Answer:
The answer would be Hydrophobic tail and a hydrophilic head. Just some background info, this is located in the cell membrane and the cell membrane is made of up something called the Lipid Bilayer. The word "bi" means 2, so it comprise of 2 layers of phospholipids. These 2 layers of phospholipids are called hyrodrohpbic and hydrophilic. The word "phobic" means fear, so they hydrophobic molecules are NOT attracted to water. Hydrophilic molecules, however, ARE attracted to the molecules.

Lungs in humans and many other species branch out into many tubes until they end in small sacks called alveoli. These alveoli allow oxygen to enter the blood through the capillary beds as pictured above. Alveoli provide much more surface area for the lungs to contact the capillary beds. What is the advantage of lungs with alveoli compared to lungs without alveoli?
Answers
Answer:
It provides more surface area for the absorption of oxygen.
Explanation:
The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.
What is Cellular respiration?In the presence of oxygen, cellular respiration is a chemical process that converts a substance with six carbons into three carbon dioxide and water molecules and enormous amounts of energy in the form of ATPs.
Simply put, cellular respiration is a sequence of metabolic processes that happen inside a cell. For usage in the energy-demanding processes of the cell, biochemical energy is extracted from organic materials.
It is stored in energy-carrying biomolecules (such as adenosine triphosphate or ATP).
Therefore, Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.
