Your breathing will become more shallow and heart rate will increase. This is the bodies response to physical exertion in order for the body to be oxygenated faster.

Your breathing increases, because your body is demanding more oxygen for delivering the right of amount of blood (flow) to the muscles, as well as the heart.

When your body exerts itself more than it's normal state, your muscles want more oxygen for the creation of ATP.

Give one example of a factor that can influence airflow resistance.
irga5000 [103]

Answer:

Airways diameter can influence the airflow resistance.

Explanation:

Airflow resistance follows the same principle followed by the airway resistance. This is the resistance offered during the pulmonary blood flow.

Airways diameter affects the airflow resistance. If the diameter of airway is increased, the airflow resistance decreases and air can flow easily in the body. The decrease in the airway diameter (dilution) increases the airflow resistance of the blood artery.

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t
Gelneren [198K]

Answer:

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

  • A (colored seed) is dominant over a (colorless)
  • Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).

  • The homozygous recessive can only produce <em>a wx </em>gametes.
  • The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>

<u>The possible offspring resulting from the combination of those gametes is:</u>

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).
