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.

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.

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.

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.

Answer:

Alternation of generations is a type of life cycle by which species alternate haploid (n) and diploid (2n) individuals.

Explanation:

Alternation of generations refers to the life cycle observed in terrestrial plants by which species alternate between haploid (i.e., organisms having a single set of chromosomes) and diploid (2n, i.e., organisms having a single set of chromosomes) generations. Plants alternate between a sporophytic stage and a haploid gametophytic stage. This alternation of generations is accompanied by the alternation between sexual reproduction, where the fusion of male and female gametes from the gametophyte generation produces a diploid zygote that develops into the sporophyte, and asexual reproduction, where spores (generated in the sporangium of the diploid sporophyte) are released and germinate into new individuals.

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.

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.

Answer:

During meiosis , four daugther cells are produced

Answer:

4 cells. You end up with four cells.

Explanation:

Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.

Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

Answer:

A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.

Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.

I hope this answer and explanation helped you understand this topic a little bit more!

The diaphragm is located in inferior to lungs.

In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.

It is the primary respiratory muscle.

The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.

Vacuum is created due to contraction, which pulls air into the lungs.

Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.

So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

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.

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.

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.

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.
