Incomplete dominance shows phenotypes of both dominat and reccessive trait !!

so supppose red is AA
the white is aa
and pink is Aa (heterozygous thus pink)

on crossing Aa to Aa (two pink)

we have ; AA , Aa, Aa, aa

thus 1 red, 2 pink, 1 white
Ratio - 1:2:1

When you are injured and bleeding the clotting factors immediately start to clot and try to seal the wound. This would be an exa
Juliette [100K]

Explanation:

This would be an example of secondary homeostasis

During wound healing, which happens after bleeding from a cut, the homeostatic response is clotting; primary homeostasis involves the formation of a platelet plug at the site, from platelets within the blood

Fibrinogen and platelets form a clot, in order to prevent blood loss and infection.  Fibrin is formed through the activation of coagulation factors which stabilise the plug.

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

Please help!!!
Sever21 [200]

Answer:

Hardy-Weinberg equilibrium AND IF you assume that red hair is a simple recessive trait, then

q^2 = 0.12

q = 0.35 and p = 0.65

p^2 would equal proportion of population that is homozygous = 0.42, so 42% of the population is homozygous for non-red hair.

Explanation:

Hormones play an important role in regulating blood glucose levels. what is an example of this?
Ber [7]
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme.  It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)
