Stress increases the release of cortisol, and the cortisol
helps people cope with the stress. If stress continues for prolonged periods of
time: the increased cortisol begins to have adverse effects on bodily and
mental functioning. Increased activity in the dopamine reward systems, the same
systems involved in drug addiction.
Answer:
1/4 or 1/2 depending on mating partner of F2
Explanation:
Assuming that the F1 parent Rr mated with a plant with the RR, Rr or rr genotype the F2 offspring would have the following genotypes:
Rr x RR= 1/2 RR, 1/2 Rr
Rr x Rr = 1/4 RR, 1/2 Rr, 1/4 rr
Rr x rr = 1/2 Rr, 1/2 rr
The F2 generation with the RR genotype could not be the parents of the F3 generation because to have individuals with the rr genotype the F2 generation would have to mate with a plant that is either Rr or rr in which case the fraction of the population with the stripe rust phenotype will either be 1/4 or 1/2, respectively.
The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

What is the circulatory system?
The circulatory system can be referred to as a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of humans or other vertebrates.
The circulatory system includes the cardiovascular system, also known as the vascular system which consists of the heart and blood vessels.

Answer:
Intramuscular
Explanation:
Intramuscular is a method of administering injection directly into the muscles for effective functioning.
Long acting penicillin are administered intramuscularly because of penicillin sensitive microorganisms that are subsceptible to low serum levels which is associated with penicillin dosage in the body and penicillin Has low level of solubility therefore it is slowly released into the muscles sites.
Sunlight is an unseen factor that affects the carrying capacity of the ocean.
<h3>What is Carrying capacity?</h3>
Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat.
The other options under this question are water chemistry, water availability, space, and sunlight.
Water availability and space both are unlimited in the ocean habitat, while the water chemistry remains the same throughout the ocean.
Therefore, sunlight is an unseen factor that affects the carrying capacity of the ocean.
