Botox injections comprise Botulinum toxin and is used in the treatment of some kind of eye ailments, like strabismus (crossed eyes) and blepharospasm (involuntary blinking), to treat movement disorders (like torticollis, cervical dystonia) or muscle spasms/stiffness.

The answer is B. a nucleus.
Prokaryotic cells do not have a nucleus. They have ribosomes, a cell membrane, a cell wall, and DNA, but lack a nucleus. Prokaryotes also don't have mitochondria or chloroplasts and generally lack organelles.
Answer option:
1. duplicate themselves
2. convert energy
3. selectively exchange materials
4. all of the above
Answer:
4. all of the above
Explanation:
Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.
They can convert glucose into cellular energy (ATP) through respiration in the mitochondria
They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.
Therefore, all of the above is correct.
<span>Plasma cells, they are also called plasma B cells, or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system. Plasma cells originate in the bone marrow; B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph,</span>
