Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.

Why do you get thirsty after eating salty food osmosis.

ziro4ka [17]

Answer:

As the saltier blood circulates through the body, it makes the fluid outside of our body cells saltier than the fluid inside the cells. The cells notice the change right away. That's because the extra salt outside acts like a magnet, pulling water out of the cells.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po

kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1

A client with suspected myasthenia gravis is to undergo a test with edrophonium. the client asks if edrophonium can be used to t

olga nikolaevna [1]

The correct answer is: the short half-life of edrophonium makes it impractical for long-term.

Edrophonium is used for the diagnostic of myasthenia gravis. In patient with myasthenia gravis, the body produces autoantibodies which inhibit nicotinic acetylcholine receptors in the neuromuscular junction. Edrophonium, on the other hand, is acetylcholinesterase inhibitor which blocks the effect of acetylcholinesterase enzymes (AcH stays in synaptic cleft).

Substitution for the edrophonium is pyridostigmine which is also acetylcholinesterase inhibitor but with long-term maintenance.
