All pros when conducting a lab experiment except?

Biology
1 answer:
Mrac [35]3 years ago
6 0

Answer:

I personally believe that lab experiments are useful and an effective way to test and gather data. Even though they can often lack ecological validity and mundane realism they can easily be replicated and results can be retested, helping to prove/disprove data, ultimately leading to the creation of practical applications.

  • That psychologist can make statements about cause and effect because they involve the deliberate manipulation of one variable while trying to keep the other variables constant, unlike non-experimental methods.
  • Lab experiments can also be replicated due to the standardised procedures and measures, ultimately making it easier to check the reliability of the research/results and prove/disprove results if the research is conducted by another researcher.

Inhibin secreted by granulosa cells selectively inhibits secretion of FSH by the pituitary
garik1379 [7]

Answer:

The correct answer will be option-true.

Explanation:

Follicular stimulatory hormone or FSH and inhibin are the complex proteins which play a various biological role in the reproductive system.

The FSH stimulates the secretion of inhibin from the gonads in both males (Sertoli cells) and females (granulosa layer). The production of inhibin suppresses the secretion of FSH from the pituitary gland.

The suppression of FSH directly suppresses the secretion of further inhibin and thus, option-true is the correct answer.

How is wind energy better than other renewable resources?
schepotkina [342]

Explanation:

Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.
