1. Explain why some heterotrophs can be described as both a primary consumer and a secondary consumer. What are these heterotrophs called
Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.
Natural proteins most commonly contain linear polypeptides between 100 and 1000 residues in length. One of the reasons polypeptides outside this range may be disfavored is that

answer A
Explanation:
1. Hypothesize in what type of environments it would be advantageous for a protist to be autotrophic, heterotrophic, or mixotrophic.
Answer:
See below
Explanation:
Protists fall into the category of eukaryotes. They are diverse in nature and typically are found to be single celled organisms containing very organized structures.They are classified based on what is their source of nutrition.
Autotrophic - capable of photosynthesis to produce their own food, so an environment where sunlight, CO2 and water is available.
Heterotrophic - feed on other organisms , an environment where prey is plenty and very limited or no access to sunlight.
Mixotrophic - a combination of the above two, an environment with all of the aforementioned factors present.

36% of your study population are h recessive for fingernail growth rate. Using the Harvey Weinberg equilibrium equations (P+Q = 1 and P2+2PQ+Q2 = 1), calculate the frequency of h dominants and heterozygotes in your population.
Answer:
frequency of h dominant = 16%
Frequency of heterozygotes = 48%
Explanation:
The computation of frequency of h dominants and heterozygotes in your population is shown below:
Since it is mentioned that
q^2 = 36%
So q = 0.6
And
p + q = 1
So, the p is 0.4
Now the frequency of h dominant is
= p^2
= (0.4)^2
= 16%
And, the heterozygotes in the population is
= 2 × p × q
= 2 × 0.4 × 0.6
= 48%

Compare and contrast the contributions of Neel, Pauling, and Ingram to our understanding of the genetic and molecular basis of sickle cell disease (SCD).
He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.

Does birds kill their young
Answer:
It depends.
Explanation:
Often times, first-time mothers will not know what to do with their young and accidentally kill them.
Other times, birds will kill their young because the chicks fall ill, and the mothers do not want the sickness to spread to the rest of her chicks.
But for the most part, mothers will keep healthy young and try to keep them alive.

How does the vessel diameter of the afferent arteriole change in order to decrease glomerular hydrostatic pressure (GHP) and restore the glomerular filtration rate (GFR) to normal
Answer:
The afferent vessel will generate vasodilation, that is, increase its diameter to generate a stirring effect in the glomerulus, promote glomerular filtration and decrease pressure in it.
Explanation:
The renal glomeruli are in charge of filtering the blood.
They have an efferent vessel that collects the blood to be filtered and an afferent that is in charge of returning it to the bloodstream of systemic circulation.
When the pressure of the glomerulus is very high, the glomerular filtration rate is increased and it needs to be regulated, that is why the afferent vessel undergoes vasodilation to decompress the glomerulus pressures and thus regulate the filtration rate by decreasing it.

The genomic DNA of an organism has a base composition of 40% C-G base pairs and 60% A-T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
Answer:
The correct answer is (0.2)^4.
Explanation:
Based on the given information, the given genomic DNA is A-T rich, and the base pair composition is C-G = 40 % and A-T = 60%. Therefore, as per Chargaff's rule, Each C and G will possess 20%, and each A and T will possess 30%.
Therefore, the probability of each base will be,
C = 20/100 = 0.2
G = 20/100 = 0.2
A = 30/100 = 0.3
T = 30/100 = 0.3
Now the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' will be 0.2 * 0.2 * 0.2 * 0.2 = (0.2)^4.

The nerve cells in your body must constantly remove substances from the cell against the concentration gradient. What type of process most likely takes place to remove substances from a cell against the concentration gradient? Explain.
Answer and explanation:
Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.
The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.
