. The number and type of prey items found in the owl pellet can be the result of the following factors: availability and abundance of prey, the ease or difficulty of catching the prey, and the taste preference of the owl. Create an experimental design that would describe the diets of barn owls while accounting for these factors.

Answers

Answer:Check for availability of prey in same habitat as the Barn owlDetermine the type of  prey available in the habitat because Owls feed mostly on small rodents like mice, vole e.t.cIf there is an abundance of prey, Check for the most common and easy to catch prey for an owl . considering the taste of the Barn owls while carrying out this experiment . The Barn Owls feed mostly on Field voles to other kinds of rodents. therefore the availability and ease of catching a Field vole should be prioritized if they are readily available in the same habitat with the Barn Owls. if Field voles are not available the Barn owls can also feed on other rodents and smaller birds available .Conclude your experiment

Explanation:

Experimental design based on the factors mentioned

Check for availability of prey in same habitat as the Barn owl

Determine the type of  prey available in the habitat because Owls feed mostly on small rodents like mice, vole e.t.c

If there is an abundance of prey, Check for the most common and easy to catch prey for an owl . considering the taste of the Barn owls while carrying out this experiment .

The Barn Owls feed mostly on Field voles to other kinds of rodents. therefore the availability and ease of catching a Field vole should be prioritized if they are readily available in the same habitat with the Barn Owls. if Field voles are not available the Barn owls can also feed on other rodents and smaller birds available .

Conclude your experiment

The diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.

What do you mean by Prey?

Prey may be defined as an animal or any other organism that is hunted or killed by another animal for the purpose of food.

Barn owl decides its food on the basis of availability and abundance of prey because in order to survive barn owl checks the presence of a particular prey that are easily available and found in high number. Mostly barn owl prefers small species of rodents like mice, young one of rabbit, and sometimes birds.

Other than this it also depends on how much energy is required to catch the particular prey because if the energy is greater than that of benefit, barn owls eliminate this behavior.

And last barn owls choose those prey that is palatable in nature and have good taste. Bad taste or toxic taste is eliminated in nature.

Therefore, the diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.

b. The double helix unzips at the phosphate bonds and new nucleotides pair with the appropriate sugars.

c. The double helix unzips the hydrogen bonds between bases and new DNA nucleotides pair with the complementary bases in the old strands.

d. The double helix unzips and RNA forms base pairs with the complimentary strand of DNA.

Answers

Answer:

By hydrogen bonds between nucleotide bases

Explanation:

A DNA molecule is a double-stranded molecule that is informing one structure two strands of nucleotide are involved.

The double-stranded molecule backbone is composed of the phosphate and sugar group and the inside of the backbone are presents the nitrogenous bases. The nitrogenous bases are of four types which are: adenine, cytosine, guanine, and thymine.

These nitrogenous bases are attached according to the Chargaff rule that is adenine binds thymine and cytosine binds guanine. These bases bind with the help of the hydrogen bond as 2 hydrogens participate between adenine and thymine and 3 hydrogens participate between cytosine and guanine.

Thus, hydrogen bonds between nucleotide bases is correct.

As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.

Answers

Answer:

bacterial

Explanation:

A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.

According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.

Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.

How can poor nutrition lead to a change in trait expression?

Answers

Answer: Poor nutrition won't provide healthy amounts of energy to the body.  The lack of nutritional vitamins that the body needs can lead to a change in hormonal signals, stimuli, and metabolites.

Hope this helps :)

In the overall health management, nutrition plays a very recognizable function, however, the role of genetics in nutritional impact is yet to be understood completely.  

Genetic variability in relation to nutrition may be partly accountable for differences among the individuals in metabolism, absorption of food, enzyme digestion, excretion, storage, and others.  

Nutrigenetics and nutrigenomics are the two areas of study regarding genetics and nutrition that looks for the effect of genetic variations on dietary responses, and the function nutrients perform in bioactive food compounds and expression of the gene.  

• The three prime factors in nutrigenomics and nutrigenetics are ethnic diversity, malnutrition, and availability of food.  

• In the existence of chronic malnutrition, the genomic stability and gene expression can be influenced, with genome stability sometimes resulting in mutations of gene sequences and mutations at the levels of chromosomes.  

Thus, poor nutrition can result in the change in the expression of trait.
