Answer:
The correct answer is "There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include: multiple receptors for the same hormone, a single receptor coupled to different pathways and hormones interacting with receptors for other molecules".
Explanation:
Hormones are among the most versatile molecules of the body, responsible for different biological processes such as human growth, sex development and metabolisms. Hormones are responsible of these complex biological processes because they have drastically different effects in different cells. There are several mechanisms that explain why a hormone have different effects in different cells. These mechanisms include:
- Multiple receptors for the same hormone. For instance, there are multiple receptor for dopamine, a hormone and neurotransmitter responsible for different functions such as movement, memory, sleep and motivation.
- A single receptor coupled to different pathways. Most hormone receptors act with a cascade of signaling. This in consequence results in a single receptor interacting with different molecules having multiple effects.
- Hormones interacting with receptors for other molecules. One example is the action of one metabolite of progesterone named allopregnanolone. This metabolite interacts with GABA-A receptor, which gives it anxiolitic properties.
In about 25-33% of patient cyclothymic mood swing develop into full brown bipolar disorder. In cyclothymic disorder moods swing is a short period of mild depression and hypomania, an elevated mood. High and low mood swings never reach the severity of major depressive and the people with cyclothymic disorder have milder symptom which occurs in full brown bipolar disorder.
Answer:
Warm air is cooling quickly.
Explanation:
Hot air rises and cool air sinks.
Answer:
ABC transporter protein
Explanation:
ABC transporter protein refers to the ATP binding cassette protein which utilizes the AT energy to transport the substrates from one side to another side. The ABC proteins are one of the oldest proteins known in the organisms.
The CFTR protein which acts as a chloride channel in the membrane which transports the chloride ions across the membrane utilizes the ATP energy in the transport.
Thus, ABC transporter protein is correct
Answer:
The correct answer is - 0.72 pg.
Explanation:
A we know that, genetic material present in one primary spermatocyte divides in between four sperm cells that means that each sperm cell has 25 percent of DNA or genetic material of the primary spermatocyte.
Given:
1 sperm cell = 0.18 nuclear DNA
So,
0.18*4 = DNA content of primary spermatocyte
DNA content of primary spermatocyte = 0.72 picogram
