Answer: Hypoxia

Explanation: hypoxia induces the production of erythropoietin, which is a hormome produced by the kidneys to help increase the productiom of red blood cells in the body. In Jessica's case, she might be experiencing this due to a change in ultitide whereby her body needs more oxygen than it originally gets (crllular hypoxis), therefore, her body signals for more red blood cell production. The erythropoietin will then be secreted and more red blood cells will be formed by the bone marrow through the hormonal action.

The lock-and-key mechanism refers to a) the complementary shapes of an enzyme and a substrate. b) the attractive forces between
podryga [215]

Answer:

A. The complementary shapes of an enzyme and a substrate

Explanation:

The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,

LiRa [457]

Pectoralis minor is the muscle which limits scapular upward rotation, posterior tilting, and external rotation when under excessive passive tension.

<h3>What is Pectoralis minor?</h3>

This muscle is found below Pectoralis major and originates from the middle ribs to the scapula.

When under pressure this muscle limits the various types of movements which are mentioned above.

In a certain population of fruit flies, 640 out of 1000 have red eyes, while the remainder have sepia eyes. The sepia eye trait
irga5000 [103]

Answer:

The correct answer is 160.

Explanation:

Based on the given question, the total number of fruit flies is 1000, of which red eye flies are 640. Thus, the number of sepia eye flies will be 1000-640 = 360.  

On the basis of the Hardy-Weinberg equation, p+q = 1, in which p is the rate of recurrence of one allele, that is, dominant and q is the rate of recurrence of the other allele, that is, recessive.  

q^2 for the population is 360/1000 = 0.36, q = 0.6.  

Therefore, p = 1-q = 1-0.6 = 0.4.  

The frequency of homozygous dominant allele is denoted by p^2 = 0.16.  

Hence, the number of homozygous dominant for red eye color would be 16% of 1000 which will be equal to 160.
