Explanation:
When a population is genetically diverse there is a higher probability for some individuals in that population to survive during harsh conditions such as drought due to their highly resistant genes.
How is  eukaryotic RNA processed before leaving the nucleus 
Answer:
Messenger RNA, or mRNA, leaves the nucleus through pores in the nuclear membrane. ... During mRNA processing, the introns (non-coding regions) of the pre-mRNA are removed, and the exons (the coding regions) are spliced together. Additionally, a 5' cap and a 3' poly A tail are added to the pre-mRNA

What statements are true about glycolysis?
Select all that apply.
it consumes some ATP as well as producing it
it produces ATP that can be directly used by cells
o it does not directly require oxygen to operate
o it produces more ATP than any of the other respiration reactions
Answer:
true it consumes some ATP as well as producing it
true it produces ATP that can be directly used by cells
true it does not directly require oxygen to operate
false it produces more ATP than any of the other respiration reactions
Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.
What is ATP?ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.
Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.
Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

Edman degradation can be used to A) identify the N-terminal amino acid of a polypeptide. B) identify the C-terminal amino acid of a polypeptide. C) separate the subunits of a multi-subunit protein. D) cleave a protein at specific sites. E) cleave disulfide bonds within a protein so that the individual polypeptides can be separated.
Answer:
A) identify the N-terminal amino acid of a polypeptide
Explanation:
Edman degradation is a series of chemical reactions that enables the stepwise cleavage of the amino-terminal residue from a peptide/protein. This method sequentially removes N-terminal residues without disrupting peptide bonds between other amino acid residues, thereby obtaining the amino acid sequences from the target peptide/protein. Edman degradation can be defined as a cyclic method in which each residue is cleaved off from the amino-terminal end of the peptide/protein and then identified by reverse-phase chromatography, which is a technique used to separate peptides/proteins on the basis of their hydrophobicity.
What is an example of a direct effect that would result from an increase in deer mouse in this food web
Answer: increase in predator population.
Explanation: mouse deer are prey for some animals like tigers. So if their population increased, the tiger's also will or the predators'. Then it will immediately be followed by a decrease in both the prey and the predator's population.
Explain how 2 polynucleotides can twist helically around each other to form a double helix of DNA?
Explanation:
The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself. Most naturally occurring DNA spirals clockwise.The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.
Answer: small groups of individuals leave their home population and establish new settlements, mating only among themselves.
Explanation:
The founder effect is what happens when a small group of individuals leave their home population in order to establish new settlements. They will then mate only amongst themselves and colonize the area without mixing with the natives.
As a result of the founder effect, there is less genetic variation in the new population than in the home one because the smaller number of individuals who left would not possibly be able to carry all the genes in the home population. The only genes that would be passed on are those of the small individuals.

ဝod
When blood pressure drops, receptors in blood vessel walls tell the heart to beat
more strongly and increase the volume of blood flowing.
Answer:
I believe D!!
Explanation:
hope this helps :)
The feedback that controls the blood pressure has ben the dropping of blood pressures has been mediated to the slowly decrease the volume of blood flowing. Thus, option C is correct.
What is blood pressure?The pressure of the blood in the circulatory system is often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
Heart failure is common in patients with high pressure. The body’s blood pressure is a measure of the pressures within the cardiovascular system during the pumping cycle of the heart.
In this case, the higher the cardiac output, the higher the volume of the blood in the vessels. Therefore, this increases the pressure in the vessels.
So, that when blood pressure drops, receptors in blood vessel walls tell the heart to beat more slowly to decrease the volume of the blood flowing. Thus, option C is correct.

what is menstruation and why does it occurs
Answer:
A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.
It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

Is the Use of energy to move particles against the concentration gradient
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

In an experiment to investigate a factor affecting photosynthesis, a leaf of a potted plant which had been kept in the dark overnight was covered with aluminum foil as shown in the diagram below 1. Aluminium foil The set up was kept in sunlight for three hours after which a food test was carried out on the leaf. (a) Which factor was being investigated in the experiment? b) What food test was carried out? (i) State the results of the food test (ii) Account for the results in c (i) above
Answer:
Photosynthetic activity.
Explanation:
The photosynthetic activity of the plant was being investigated in the experiment and no photosynthesis will occur because the aluminium foil reflect 95% of sunlight. Starch test is the food test that was carried out in the experiment. Starch from plants is broken down into its constituent sugar molecules by the plant body in order to provide energy to the tissues so if there is no photosynthesis occurs, the plant body uses starch so decrease occur in the concentration of the starch molecules when the starch food test will occur.
