Answer: Its (D) all of the above
Answer:
The correct answer is option E. only water-soluble hormones use second messengers.
Explanation:
Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,
These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.
Thus, the correct answer is option - e. only water-soluble hormones use second messengers.
Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
Answer:
Explanation:
To say that someone is a peer implies that they are of equal standing. It can mean people who are of the same age, economic class, or grade within a profession. A peer group refers to a group of people of roughly the same age and status who spend time together. Peer pressure is the influence these people have on the life of the individual. It involves adapting behaviors that the individual would otherwise not adapt. If members of the group value a particular behavior there will be a kind of pressure to conform to this. So if friends drink alcohol, or use drugs, it can be hard to say no. Peer pressure can be a force for good or bad.
Answer:
The answer is D thalamus
Explanation:
The response to an olfactory stimulus travels through the olfactory nerve, crossing the sieve lamina of the ethmoid, located in the anterior region of the brain. From there the stimulus travels to the olfactory bulb ending in the olfactory glomeruli where aromatic signals are processed, which are conducted by special receptor cells. The information subsequently reaches the hypothalamus and the limbic system. Finally, the information reaches the temporal and frontal cerebral cortex where the odor stimulus becomes conscious.
