Part A - Calculating allele frequencies in a population The first step in testing whether a population is in Hardy-Weinberg equilibrium is to calculate the allele frequencies in the population. Remember that the frequency of an allele in a gene pool is the number of copies of that allele divided by the total number of copies of all alleles at that locus. Using the day 7 data, what is the frequency of the CG allele (p)
Answer:
the frequency of the CG allele (p) is 0.476 ≅ 0.48

Why do you think sea otters are important in the kelp forest?
Answer:
It controls the population of sea urchins.
Explanation:
Sea otters are very important in maintaining the balance of ecosystems present near the sea or ocean, such as kelp forests etc. In the absence of sea otters, sea urchins can increase in population i.e. overpopulate the sea floor and feed all vegetation of the kelp forests that provide cover and food for many other marine animals which leads to imbalance of an ecosystem so that's why we can say that sea otters are important in the kelp forest.

2 difference between meristematic tissue and permanent tissue
Answer:
1) Meristematic tissues have cells small in size, while permenant tissues have cells large in size.
2) Meristematic Tissues usually don't have a vacuole while permenant tissues do.
Answer from Gauthmath
As you saw in Part C, the body sizes of sympatric and allopatric P. cinereus and P. hoffmani are consistent with a hypothesis of character displacement resulting from interspecific competition. What additional information would strengthen the argument that character displacement is in fact responsible for body size evolution in these salamanders
Answer:
Divergence in the body size trait between both species occurred once they were living together. The evolution of the trait difference occurred after sympatry.
Explanation:
Close species, P. cinereus and P. hoffmani, mostly live in different regions. In allopatry, both species have the same -or very similar- body size. Body size in these species is a heritable trait.
However, there are some areas where P. cinereus and P. hoffmani coexist. When they are in sympatry, P. cinereus exhibits a smaller body size and feeds on smaller prey items than allopatric P. cinereus. On the other hand, sympatric P. hoffmani exhibit bigger bodies, feeding on bigger prey items than the allopatric P. hoffmani.
So, when both species are in sympatry, they develop different morphological traits to avoid competition between them and manage to coexist in the same area. Resource availability is limited, so P. cinereus became smaller and feeds on small prey, while P. hoffmani became bigger and feeds on bigger prey. Through this trait divergence, they got to live longer and reproduce more, decreasing interspecific competition and increasing their fitness.
Allopatric species feed on similar prey items and have similar body sizes, reflecting that the divergence occurred after sympatry. If species living in allopatry were places together in the same habitat, they would exhibit strong competition that, over time, would drive to character displacement.

As you know, coronaviruses, influenza viruses, measles viruses, and rhinoviruses all encode RNA-
dependent RNA polymerases. All four of them introduce this gene into host cells. Two of them
ALSO introduce the RdRp enzyme. Which two? Why MUST they carry the polymerase protein in the
virus particle?
Answer:
In order to form more DNA molecules.
Explanation:
These viruses carry the polymerase protein in the virus particle because this protein synthesizes DNA molecules from deoxyribonucleotides. This formation of DNA molecule enables the virus cell to increase in their population. Each and every new cell of virus requires DNA molecules so we can say that this polymerase protein is very important and necessary for virus.

what produce energy from food during respiration
Answer:
The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration. Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.
How are all fungi and all protists alike?
Explanation:
Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. As eukaryotes, both fungi and plants have membrane-bound nuclei, which contain DNA condensed with the help of histone proteins.
Help!! please just a bit confused
Answer:

Chang wants to build a circuit that will light up a bulb from a flashlight, and has a battery, switch, wire, and a light bulb.
Which component would Chang use as the source of energy?
the battery
the switch
the wire
the light bulb
The battery component would Chang use as the source of energy.
What is Battery?Batteries consist of one or more cells, each of which undergoes chemical processes to produce an electron flow in a circuit.
Each battery has three primary components: an anode (the "-" side), a cathode (the "+" side), and an electrolyte of some sort.
When the cathode and anode of a battery are connected to a circuit, a chemical reaction takes place between the anode and the electrolyte. Following this reaction, electrons return to the cathode and experience a second chemical change.
Therefore, The battery component would Chang use as the source of energy.

What renal actions does angiotensin II have that are not related to its ability to produce vasoconstriction
Answer:
Angiotensin II is a main effector of RAS and is produced due to the release of the renin that forms in the kidney, angiotensin in turn stimulates the release of aldosterone from the adrenal cortex.
Angiotensin II serves various roles other than vasoconstriction to maintain blood pressure that are:
1. Autoregulation of GFR
2. Reduction of salt excretion through direct and indirect actions on renal tubular cells,
3. Growth modulation of renal cells - these express AT1 receptors.

Allosteric effectors: Question 1 options: can lead to a decrease in the availability of a protien alter enzyme activity by binding to the active site of an enzyme can cause large changes in enzymatic activity decrease the sensitivity of the enzyme at nearly all concentrations of substrate do not alter the sensitivity of a metabolic pathway
Answer:
can cause large changes in enzymatic activity
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Additionally, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Furthermore, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction.
In the human body, the optimal temperature for enzymes is around 37 degrees celsius (°C).
In conclusion, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

Explanation:
How do superantigens enable pathogens to hide from the immune system if they actually stimulate the immune system? They cause the immune system to produce an exaggerated response, distracting it from the actual pathogen. They cause fever, which destroys the complement proteins. They cause the immune system to destroy IgA antibodies. They cause the immune system to turn on itself.
Answer: They cause the immune system to produce an exaggerated response, distracting it from the actual pathogen.
Explanation:
Superantigens are a type of bacteria that suppress the immune system by excessively activating it. They cause the creation of non-specific T-cells which then causes the body to look for other organisms apart from the pathogen.
With the immune system distracted, the pathogen then infects the body thereby making these pathogens particularly dangerous.
