Answer:
Option (b), (c) and (d).
Explanation:
Prokaryotes lacks the membrane bound organelle and the nucleus is absent in the prokaryotes. Prokaryotes includes only the simple organism like bacteria.
Prokaryotes have the cell wall and the cell membrane. Prokaryotes multiply by asexual reproduction and mitosis is absent in prokaryotes. The prokaryotes have single circular shaped chromosome DNA prsent inside the nucleoid.
Thus, the correct answer is option (b), (c) and (d).
Answer:
According to the warning signs that exist in radiology clinics, a pregnant woman should consult her physician before undergoing an x-ray study because x-rays are a form of ionizing radiation that can affect the development of a gestational baby.
Explanation:
<em>Signs/notices in radiology clinics indicate that women who are pregnant or suspect they may be pregnant should consult their doctor before undergoing a radiological examination. Why should they do it?</em>
X-rays are a type of electromagnetic radiation -ionizing- capable of passing through the body, used to obtain images of the interior of an organism by capturing these rays on photographic film.
It is well known that X-ray radiation can have mutagenic effects on living organisms, according to the amount of radiation and the time to which it has been exposed. In the pregnant woman, who has a fetus developing inside her, special attention must be taken due to the harmful effects that ionizing radiation can have on its development. This is the main reason why a pregnant woman should consult her doctor before undergoing a radiological study.

Explanation:
Answer: Option A.
Transverse tubules rapidly move the action potential to the interior of the muscle potential.
Explanation:
Transverse tubules are cylindrical pockets found in the plasma membrane of muscle cells. They are formed from phospholipid bilayer or sarcolemma of skeletal or cardiac muscle cells. They have membrane that have large concentration of ion channels,transporters and pump. They permit action potention into the cell and also to a particular structure sarcuplasmic reticulum. They play a role in regulating cellular calcium concentration.
Electron microscope‘s differ from light microscope’s in that they produce an image of specimen by using a beam of electrons rather than a beam of light. Electrons have such a shorter wavelength than visible light, and this allows electron microscope to produce higher resolution images than standard light microscope‘s
