Answer:
Adrenal medulla
Explanation:
Fight-or-flight or acute stress response is marked by physical changes, including nervous and endocrine changes, that prepare human or an animal to react or retreat. This response was first discovered by an American Physiologist, Walter Bradford Cannon.
In response to an acute stress, an area of the brain called AMYGDALA sends an emergency signal to the HYPOTHALAMUS, which acts like a command center and activates the body's sympathetic nervous system by releasing hormones. The sympathetic nervous system stimulate the adrenal medulla gland, triggering the release of CATECHOLAMINES (Epinephrine/adrenaline and Norepinephrine/noradrenaline) into the bloodstream.
This release induces several physiological changes in the body; The heart beats faster than normal; pushing blood to the muscles, heart and the vital organs, increased in blood pressure, blood sugar (glucose) are released into the bloodstream to give us the extra energy we need.
It is the structural isomer. It is a type of isomerism in which particles with the same sub-atomic equation have distinctive holding designs and nuclear association, instead of stereoisomerism, in which sub-atomic bonds are dependable in a similar request and just spatial game plan contrasts.
The frequencies of R is 0.75 and the frequencies for R' is 0.25.
Explanation:
Data given:
Genotype frequency of incomplete dominance on flower colour of snapdragon:
RR = red 0.5625
RR' = Pink 0.375
R'R' = 0.0625
frequency of R and R'=?
According to Hardy-Weinberg equilibrium the genetic variation in a given population is constant from one generation to other if no factors causing evolution or genetic drift is there. So,
+ 
+ 2pq = 1
The p represents = homozygous dominant RR
q represents = homozygous recessive R'R'
2pq = frequency of heterpzygous genotype RR'
= 0.5625
p = 0.75 (frequency of R)
= 0.0625
q = 0.25 (Frequency of R')
Their sum is 1 as according to Hardy Weinberg condition:
p+q = 1
mitosis, part of asexual reproduction because it produces diploids.
Mitosis is really just cell division which technically is considered asexual reproduction when organisms reproduce alone using cell division
