Answer:

superior vena cava

Explanation:

Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.

Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above

Answers

Answer:

The correct answer is - option b. to generate a protein with a run of consecutive glutamines.

Explanation:

The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.

So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.

Answers

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

The function the eyes performs requires more precise locomotion control than the movement of the limbs require.

For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.

This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.

In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

Birds belong to different species but share similar characteristics. What inference can be correctly drawn about this statement? (5 points)


Group of answer choices


All birds share the same habitat.


All birds produced similar offspring.


All birds reproduce with genetic variation.


All bird species adapt through evolution

Answers

Answer:

All bird species adapt through evolution

Explanation:

The correct answer would be that all birds reproduce with genetic variation and adapt through evolution.

Sexual reproduction causes genetic variation in sexually reproducing organisms due to crossing over and a random assortment of genes. Birds can only reproduce sexually and hence. they produce offspring that are genetically different but that might share many similar characteristics.

Evolution refers to the development of complex organisms from simple ancestral ones. Organisms change and evolve as they constantly try to adapt to their changing environments. Hence, organisms of the same species growing in a different environment might end up becoming different species as a result of adapting to their different environments, although they would still have some similarities to one another. In other words, evolution has a tendency to cause speciation.
