The answer that fits the blank provided above is STEROIDS. Steroids are fat-soluble signal molecules. This is one of the derivative compounds of cholesterol along with Vitamin D and bile salts. All steroid hormones are considered as a derivative of cholesterol. The answer for this would be option D.
Answer: negative feedback
explanation: negative feedback is essentially a counter action that occurs in order to maintain homeostasis within the body. if the body is too hot, it produces sweat to let off the heat (returning it to its normal temperature)
Answer:
Genetic material
Explanation:
Conjugation is one of the ways by which bacteria exchange their genetic material (horizontal gene transfer). Two bacterial cells must physically connect in order to perform the conjugation. The linking occurs through a pilus.
Pilus is an appendage on the surface of bacteria cell and it is also called fimbria. Pilus is filamentous, tubular and composed of oligomeric proteins-pilin.
Donor cell contain pilus that will attach to the recipient bacterial cell and induce the transfer.
The answer is UAC.
In the RNA, base complements are adenine - uracil (A-U) and guanine -cytosine (G-C). So, when in the process of translation, anticodons of tRNA pairs with codons of mRNA, the complementary bases will pair. So, adenine in tRNA will pair uracil in mRNA (A → U), uracil in tRNA will pair adenine in mRNA (U → A), and guanine <span>in tRNA will pair cytosine in mRNA (G </span>→ C):
tRNA: A U G
mRNA: U A C
