Nucleolus is not connected to the nucleus via nuclear pores.
<span>Nuclear pores are protein complexes that cross double membrane of the nucleus and allow the transport of molecules across the nuclear envelope (double membrane): from the nucleus to the cytoplasm (RNA and ribosomal proteins) and into the nucleus (proteins, carbohydrates, signalling molecules and lipids).</span>

The question is incomplete as it does not have the options which are:
a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
b. The woman may have different gender babies.
c. The woman with less stretch marks has larger skin cells.
d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.
Answer:
The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
Explanation:
The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.
These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.
Thus, the selected option is correct.
The right answer is The number of adenine will be equal to the number of thymine.
Chargaff's rules indicate that the DNA of any cell or organism must have a ratio of 1 to 1 between purine bases and pyrimidine bases and, more specifically, that the amount of guanine is equal to the amount cytosine, and that the amount of adenine is equal to the amount of thymine. This trend is found in both strands of DNA.
Answer: Electromagnetism
Explanation: Electromagnetism is one of the four fundamental forces (the other three are gravity, strong nuclear force and weak nuclear force.) It acts between all the particles having an electrical charge.
