When the same gene was sequenced in a different person, the sequence was ATTTAGCC

1 answer:

8 0

The different DNA sequence for a gene shows that same character can be expressed in 2 or more forms. Alleles are present on homologous chromosome.

Explanation:

The gene is the DNA sequences on the chromosome coding for the particular trait in an organism.

The alleles are the variant of the gene. In a homologous chromosome the variant of the gene or allele is present. The homologous chromosome is present in progeny one from each parent.

For example the allele for tall as homozygous is present on one of the parent and shortness on the other parent in homologous chromosome. The trait of height is the gene and the way it expresses itself is the trait from either parent. The DNA sequence will also be different for the alleles because they will code for different proteins like short or tall phenotype.

The genotype will be different hence DNA sequence is also changed.

What would happen if the pouter pigeon and the fantail pigeon and the fantail pigeon were selectively bred?

lozanna [386]

<h2>Answer:</h2>

The offspring population will contains the desirable characteristics of both fantail pigeon and the fantail pigeon.

<h3>Explanation:</h3>

The selective breeding is the planned breeding between two organism of the population with desirable properties to result in the new traits from both parents in the single next generation offspring.
In this case, the offspring of the pouter pigeon and the fantail pigeon will contain the traits of pouter and it also has fantail.
The new generation will be selective breed an it is from the breeding of intra specie organism. If breeding is inter specie than the offspring is most probably infertile.

You have just delivered a premature baby. Your assessment reveals that he is breathing adequately; however, his heart rate is 90

s2008m [1.1K]

Answer:

The answer is letter B, keep him warm and ventilate with BVM.

Explanation:

In order to know more about the answer, let's check out the meaning of "Premature Baby" first.

Premature Baby- a baby born through premature birth <em>(fewer than 37 weeks).</em> Babies are normally born at the usual <em>40 weeks.</em> Health problems may occur with premature babies, thus it is very important to monitor them.

In the situation above, the premature baby's heart rate is only 90 beats/min. <em>A resting heart rate for a newborn infant is 130-150 beats per minute. </em>This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). <u><em>An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate. </em></u>

<u><em>Remember: </em></u>Inhalation increases the heart rate.
