Burrowing owls sometimes build their nests in holes that were dug by prairie dogs, coyotes, or badgers and have been since abandoned. They sometimes line the nests with cattle or horse dung. Why
Answer:
To avoid extreme temperature and keep away predators.
Explanation:
Burrowing owls sometimes line the nests with cattle or horse dung in order to avoid extreme temperature. The cattle dung protect the Burrowing owls from extreme temperature of the surrounding so they make nests close to these cattle dung. These dung has many insects which is a food of Burrowing owls and this cattle dung also keep predators away from Burrowing owls.

g The dominant food chain in a kelp forest ecosystem is made up of the three species below, listed with their trophic levels. If sharks enter a kelp forest ecosystem and begin feeding on sea otters, they would have a positive indirect effect on which species
Answer:
Crustaceans, sea urchins, mollusks and fish.
Explanation:
The positive effect occurs on crustaceans, sea urchins, mollusks and fish if the shark feeds on sea otter because sea otter feeds on crustaceans, sea urchins, mollusks and fish. Decrease occur in the population of sea otter due to introduction of shark in the ecosystem which indirectly increases the population of crustaceans, sea urchins, mollusks and fish. So we can say that a positive indirect effect occurs on crustaceans, sea urchins, mollusks and fish due to shark.
25. A cell has 20 amino acids. How many molecules of tRNA are in the cell?
1. Four
2. Three
3. More than 20
4. At least twenty
5. Fifteen
6. I do not know.
Answer:
I think no 3 will be the answer.
In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.
What is tRNA?Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.
There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.
Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.
Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.

What do you predict would happen if hydrogen bonds formed between any two nitrogenous bases in DNA ?
Answer:
I believe replication would not be possible, therefore the DNA would cease to help recreate cells which are essential to the human body.
Explanation:
This question by far is highly interesting, in fact it is very controversial too. However, with the sudden beginning of an actual hydrogen bond forming within nitrogenous bases, then replication would not be possible. This is so because replication relies only on nitrogenous bases rather than hydrogenous bonds. Therefore, resulting in a possible defect in the process of replicating to occur. However, if possible, I believe there might be even a chance of a mutation to occur, yet that is highly rare given the stance that the DNA molecule would not be able to pretty much do anything if that were to occur.

A dispersion pattern that indicates that resources are abundant, evenly distributed with little interaction within individuals is:_______.
Answer:
Uniform dispersion pattern.
Explanation:
Uniform dispersion pattern is a type of dispersion pattern in which resources are present in abundant quantity as well as evenly distributed with little interaction within individuals. Due to abundant quantity of resources , the population of organisms increases that leads to more population of individuals in the ecosystem. Due to abundant amount of resources, there is less competition as well as interaction between individuals that are present at that time.
Are there telomeres on both the leading and lagging strand of DNA?

This nucleic acid has
three-nucleotide codes called ______
The three-letter codes are complementary
to ________
on ________
molecules. Each of these
molecules brings with it an amino acid, which will become part of the growing polypeptide.
Answer:
The correct answer is - mRNA, codons, anticodons, RNA.
Explanation:
During the translation process of protein synthesis, the mRNA strand is attached with the ribosome in order to translate the three-letter nucleotide sequence that is called codons or triplet code into specific amino acids.
These three-letter codes are complementary to the anticodons on the RNA (tRNA) molecules. These nucleic acid molecules with ribosomes bring with them an amino acid to make a polypeptide chain.

g Name and describe two possible pathogens that could be responsible. The spinal tap reveals the presence of Gram-negative cocci in the CSF. What would be the likely diagnosis
Answer:
Explanation:
The missing information describing the status of the sick sophomore student is attached in the image below.
The first question says we should name and describe the two possible pathogens responsible for such.
The two possible pathogens are:
Virus and Bacteria.
Recall that, the College student experienced a severe headache, nausea, vomiting, neck stiffness, and fever.
These highlighted symptoms are commonly caused by meningitis which is a bacterial infection.
Surgeons, surgical tools, and scrub nurses must all be sterile when doing surgery; If any infection arises provided all crucial measures were not taking into consideration, it would harm the patient and there will be a risk of meningitis as a result of this.
SImilarly, given that In the CSF, the presence of Gram-negative cocci is shown via a spinal tap; then the likely diagnosis would be that:
The patient has suffered from Neisseria meningitis.
This is because Gram-negative cocci are the most prevalent cause of infection in persons of this age group and In the Gram stain test, it has a dark red color.

In the trp operon, tryptophan serves as a(n) ___________________, binding to the repressor and causing it to block to attachment of RNA polymerase.
a. operator
b. inducer
c. repressor
d. corepressor
e. gene
In the trp operon, tryptophan acts as a corepressor, binding to the repressor and inducing it to stop to attachment of RNA polymerase. Therefore, option D is correct.
What is trp operon?The trp operon is a group of genes in bacteria that are involved in the biosynthesis of the amino acid tryptophan. The operon is composed of five structural genes, trpE, trpD, trpC, trpB, and trpA. These genes code for the enzymes involved in tryptophan biosynthesis.
In the trp operon, the presence of tryptophan serves as a corepressor. The tryptophan molecule binds to the trp repressor protein, causing a conformational change that allows it to bind to the operator region of the operon.
This blocks the attachment of RNA polymerase to the promoter, preventing transcription of the genes involved in tryptophan biosynthesis. Thus, option D is correct.

A lipoprotein particle functions to ________. dissolve polar lipids for excretion transport nonpolar lipid to body cells metabolize lipids into new substances dissolve polar lipids in urine store lipids in the tissues
Answer:
The correct answer is ''transport nonpolar lipid to body cells''
Explanation:
Lipoproteins are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues. They transport all the lipids that circulate in the plasma: free and esterified cholesterol, triglycerides and phospholipids. Plasma lipoproteins constitute a polydisperse and heterogeneous system of particles of almost spherical morphology, which have a hydrophobic nucleus or core formed by nonpolar lipids, that is, esterified cholesterol and triglycerides, and by a hydrophilic surface layer containing unesterified cholesterol, phospholipids and specific proteins called apoproteins.
