Answer:
c stomach
Explanation:
well you can definitely rule out skin and brain as they don't even make sense as answers so only teeth and stomach are left and while saliva does have these enzymes, the teeth specifically don't so the stomach is right as its the only one that makes sense
Answer:
Option (D).
Explanation:
Steroid hormones are derived from lipids. Testosterone and estrogen are the steroid hormones. These hormones can directly diffuse into the plasma membrane.
Steroid hormones after diffusing into the cell, binds with its receptor present in the cytoplasm. Hormone with its receptor enters inside the nucleus and results in the gene transcription.
Thus, the correct answer is option (D).
The destruction of tissue by rapid freezing with substances such as liquid nitrogen is known as cryosurgery.
Liquid nitrogen is a chemical substance that has a boiling point of –320°F (–196°C). It finds its applications in a variety of things like, as a coolant, in medicines, in cryogenics, for transport, vacuum pumps, etc. Skin contact with the liquid nitrogen should be avoided as it can cause burns and even blisters.
Cryosurgery is the surgical procedure where an extremely cold liquid is used to freeze the damaged tissues of the body. It can be used to treat cancer. STDs like genital warts are also treated with this surgery.

The question is incomplete as it does not have the figure which is provided in the attachment
Answer:
D. directions for the synthesis of molecules B, C, and D
Explanation:
In the given question, the figure illustrates that there is a molecule present inside the nucleus which could form the different or other molecules through the ribosomes like the receptor molecules, the enzymes, and the hormones.
This shows that a single molecule A has the guidelines to form all of these other molecules through ribosomes. The molecule A inside the nucleus which contains all the guidelines for the synthesis of different molecules is known as DNA.
Thus, the selected option is correct.
