4. An increase in calcium concentration in the sarcoplasm will cause which of the following?A. displacement of troponin tropomyosin complex from the actin binding sites
B. muscle relaxation
C. rapid repolarization of the muscle membrane
D. breaking of the actin/myosin cross-bridges
E. activation of calcium pumps in the sarcoplasmic reticulum

Answers

Answer 1
Answer:

Answer:

B. muscle relaxation

Explanation:

Sarcoplasmic reticulum store intracellular calcium in skeletal muscle cells.

The concentration of calcium helps in the contraction and relaxation of muscles. During depolarization, the calcium concentration increases that change conformation of troponin and tropomyosin and allows the actin to bind with myosin, resulting into relaxation of the muscle cell.

Hence, the correct option is "B. muscle relaxation".

A. 4
B. 2
C. 3
D. 1

Answers

An experimental pharmaceutical is typically approved after it passes 4 phase of clinical trials.

What is clinical trial ?

Clinical trials are combination of new research, studies and experiments performed in people to evaluate the effectiveness of new experiment on human health.

It consists of main 4 phases.

Phase 4 clinical trial is also known as " Post-Approval Research and Monitoring ". It is the final stage of trial for any pharmaceutical product, drug or device. This trial study about the side effects, real life scenarios, long-term risks and benefits of particular pharmaceutical product which were not seen in the early trials.

So we can sayan experimental pharmaceutical can be approved when it passes 4 phases of clinical trials.

The law of__ states that traits are passed from parents to offspring independent of one another

Answers

The law of independent assortment states that traits are passed from parents to offspring independent of one another.

The law of independent assortment, formulated by Gregor Mendel, is a fundamental principle in genetics that describes the inheritance pattern of different traits. According to this law, the segregation of one pair of alleles (genes) during gamete formation is independent of the segregation of another pair of alleles for different traits. In simpler terms, the inheritance of one trait does not influence the inheritance of another trait.

Mendel's experiments with pea plants revealed that the assortment of alleles for one trait (such as flower color) does not affect the assortment of alleles for another trait (such as seed shape). The law of independent assortment holds true under the condition that the genes governing these traits are located on different chromosomes or are far enough apart on the same chromosome to undergo genetic recombination.
