How are gannets and sooty terms different?

1 answer:

6 0

While most terns inhabit marshes and shores, the Sooty Tern has the life of a true seabird. A long-winged flier, it wanders tropical oceans, nesting on remote islands. Many nest in Hawaii, but North American birders often seek the species by visiting the islands of the Dry Tortugas, west of the Florida Keys. Noisy around its nesting colonies by day and night; a sailors' name for the bird is "wide-awake."

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference

REY [17]

Answer:

The best answer to the question: What is the most likely explanation for this observation, would be, B: RNA processing removes the different segments from the mRNA molecules of each person prior to translation.

Explanation:

In order for cells to work, they depend on one of the four major macromolecules; proteins. These proteins are the messengers that carry out genetic commands from the DNA and they will ensure that all processes, including transcription and translation of new proteins, are carried out correctly. In order to produce proteins, the first step is for the DNA to be transcribed into mRNA, a nucleic acid that carries out the information on the DNA for protein generation. Once transcription stops, mRNA undergoes a series of clipping and reorganizing steps that will ensure that when it is decoded for protein formation, the process will be successful. These control steps are all part of the RNA processing mechanism that enures mRNA will successfully be translated into working proteins.

The reason why from genes of different people, a very similiar protein chain may result, is also explained from the fact that codons (a grouping of three nucleotides present in mRNA), when read by ribosomes, and coupled by tRNA, can pair these codons with similar amino acids. Thus, one codon, or similar codons, may code for a singular amino acid. However, mechanisms in the cells prevent these kinds of anomalies, by repairing the mRNA sequence before it is translated into protein.

A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a r

mel-nik [20]

Answer:

a) The correct answer is 1/2 or 0.5

Cystic fibrosis is a recessive disorder and her sibling has a disease but none of the parents had it. Thus, each of the parents must be the carrier of the disease, that is, both of them must be heterzygous.

So, if we cross Cc x Cc, it results in the genotype ratio of 1 (CC) : 2 (Cc) : 1 (cc)

Thus, 2 out of 4 would be the carrier of the disease.

b) 1/16

The probability of female to the carrier is 1/2

Same is the case with male partner due to the probability that he would be the carrier is 1/2

If both are carrier then, there is only 1/4 chances that the offspring will have the disease (as per cross shown above).

Now, the probability that the offspring will have the disease = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

So, $\frac{1}{2}x\frac{1}{2}x\frac{1}{4}$ = $\frac{1}{16}$

c) 1/8

The probability of female to be the carrier is 1/2

The probability male to be the carrier is 1/2

If both are carrier then, there is only 2/4 chances that the offspring will be the carrier of the disease (as per cross shown above).

Now, the probability that the offspring will be the carrier = product of all the above probabilities. (The probability of occurrence of two independent events is equal to the product of their individual probabilities).

$\frac{1}{2}x\frac{1}{2}x\frac{2}{4}$ = $\frac{1}{8}$

The tensor fascia latae is involved in hip __________.

Sidana [21]

Answer:

Abductor Muscle.

Explanation:

The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

Hope this helps!! Brainliest?? Anyways have a great day!! :))
