The answer is the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
C-14 and C-12 are carbon isotopes used to measure the approximate age of organic remains. C-12 is stable, and it does not break down into other elements over time. C-14 is not stable. It breaks down into N-14. But, in the body, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions.
A. Water being pumped in and out of guard cells.
Well, many organisms would die. Plants need light so they would die out rather quickly. The surrounding area would warm up initially due to the green house effect, but would eventually cool down.
Answer:
Glucocorticoids: alclometasone, prednisone, dexamethasone, triamcinolone
Mineralocorticoid: fludrocortisone
Vitamin D: dihydrotachysterol
Androgens: apoptone, oxandrolone, oxabolone, testosterone, nandrolone (also known as anabolic steroids)
Oestrogens: diethylstilbestrol (DES)
Progestins: danazol, norethindrone, medroxyprogesterone acetate, 17-Hydroxyprogesterone caproate.
Explanation:
These are all synthetic steroid hormones.
Answer:
The correct answer is C
Explanation:
Codominance means that the result of two different genes will give separated characteristics of both. For example, if an animal has a gene of red skin and another gene of white skin, it will have red in some parts of the body and white skin in other parts. It can be confused with incomplete dominance, which combines the characteristics of the genes, in these case the skin would be pink, the combination of white and red. People who have one gene of it are carriers of the disease of course, because it can be passed to their sons.
