Closely related species often look similar but have courtship rituals that are slightly different to ensure that mating occurs between member of the same species. The correct option among all the options that are given in the question is the third option or option "c". This is to preserve the specialties that each species have.
Follicle-stimulating hormones (FSH):
<span><span>· </span><span>In males-</span> stimulates the form<span>ation of secondary spermatocytes from </span>primary spermatocytes
</span> <span><span>· </span><span>In females-</span> stimulates the growth recruitment of immature ovarian follicles in the ovary</span>
<span> Luteinizing hormones (LH):</span>
<span><span>· </span>In males- stimulate the Leydig cells to produce testosterone</span>
<span><span>· </span>In females- stimulates theca cells for estradiol production</span>
Those are only some of the functions of those hormones. <span>Adrenocorticotropic hormones are hormones produced by pituitary glands which also indirectly have an influence on the reproductive system (male and female).</span>
The correct answer is: b. it doesn’t often reflect reality.
While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.
Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
