Examine the food web below. Suppose the local government sprayed a pesticide to kill mosquitoes. The sparrows ate the poisoned mosquitoes and died as well. What would most likely happen to the organisms in this food chain after the sparrows began to disappear?
A.
There would be an overpopulation of caterpillars, which would threaten the oak trees.
B.
The sparrows’ disappearance would not affect the other organisms in the ecosystem.
C.
Most of the organisms in the ecosystem would starve and die.
D.
The eagle would loose its primary food source and be forced to start feeding on mountain lions.
Answers
Answer:
A. There would be an overpopulation of caterpillars, which would threaten the oak trees
Explanation:
Because sparrows eat caterpillars as a primary food source, when the population of sparrows decrease, the population of caterpillars will increase. Because of this, more caterpillars will be feeding off of the oak trees, therefore threatening the oak trees. I hope this helps!

The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer.
HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys
HbS: Val-His-Leu-Thr-Pro-Val-Glu-Lys
Answers
Yes The two peptides will separate from each other in an electric field when the pH is 7.0
The two peptides wil drift/separate from each other when the pH is 7.0 because of the reaction of trypsin enzyme and also the difference in charge between HbA and Hbs
Considering charge of each peptide
Since The isoelectric point of normal Hba is 6.9 and Hbs possess two fewer negative charges per hemoglobin molecules
The Hbs is more hydrophobicity than HbA due to the substitution of glutamic acids of HbS by valine residue.
Considering Electrophoresis
At a lower pH level Hbs shows a slower moving band than Hba
while a higher pH level the HbS peptide is less negatively charged while the carboxyl group of HbA is more negatively charged and Hba moves faster as well as an acidic pH.
Hence we can conclude that the two peptides will separate from each other in an electric field when the pH is 7.0

Distinguish between dimorphic, polymorphic, and continuously variable traits.
Answers
Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:
Dimorphism is the condition of those species of animals or plants that exhibit two anatomical aspects or two different forms.When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.Continuously variable traits are those that show a continuous distribution of phenotypes.Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?
Answers
Explanation:
The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32
To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.
The Hardy-Weinberg equation is given as:
p² + 2pq + q² = 1
Where:
p = frequency of one (dominant) allele
q = frequency of the other allele (recessive) allele
p² = expected frequency of homozygous dominant individuals
2pq = expected frequency of heterozygous individuals
q² = expected frequency of homozygous recessive individuals
To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.

How does the carbon stored in the bodies of living organisms move into rocks?(1 point)
Carbon dioxide released through respiration dissolves in certain rocks, like limestone.
Living organisms decay, releasing carbon into the soil, and soil is compacted into rocks.
Living organisms decay and become fossils fuels, which eventually become rocks.
Carbon dioxide dissolves in ocean water and is slowly absorbed by rocks in the ocean.
Answers
In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. ... This carbon can then be ingested and stored in animals that eat the plants. When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals.
When animals die, their bodies degrade into the soil, encasing the carbon in layers that eventually transform into rock or minerals. hence option b is correct.
What is rock?Stone including limestone and its minerals is created when sediment and shell layers are bonded together over time.
Gases like carbon dioxide are among the forms of carbon that are stored in the atmosphere. Animals that consume the plants can then absorb and store this carbon.
When animals die, their bodies degrade into silt, encasing the carbon in layers that eventually transform into rock or minerals. Some of this silt may eventually turn into fossil fuels like coal, oil, or natural gas, which when burned, release carbon back into the atmosphere.
Therefore, when an animal dies to decompose into the soil which becomes rocks through carbon from living organisms moves into rocks, hence option b is correct.
