Using your knowledge of the normal process of gametogenesis and fertilization, formulate a hypothesis as to how a chimeric indiv
olga55 [171]

A chimeric individual is one that has two sets of genetic makeup in their body.  These individuals develop during the fertilization stage of growth and development. This occurs when two ova are each, separately, fertilized by a sperm. The two zygotes fuse, implant and begin to develop as one blastocyst. As the blastocyst develops and differentiate, some parts of the blastocyte are developed from the genetic material of one of the cell lines while other parts develop from the other cell line. Therefore, the fetus will have particular tissues and organs with different genotype from others.

Botulinum toxin is produced by Clostridium botulinum, a gram-negative bacterium. The toxin actually consists of 7 related toxins
Bess [88]

Answer:

A. Botulinum toxin possesses a heavy chain and a light chain, each of which takes part in the toxicity. The binding of the protein and its invasion within a nerve cell is permitted by the heavy chain. After the entry is permitted, the light chain functions like a protease and chops proteins, which would usually permit neurotransmitters to discharge out from the cell. This is basically a commotion of exocytosis or the discharging of neurotransmitters.  

The acetylcholine, that is, the obstructed neurotransmitter generally conducts a nerve impulse to a muscle, allowing the muscle to contract. By inhibiting the neurotransmitter, the botulinum toxin results in its distinctive flaccid paralysis.  

B. The small doses of the sterile, purified botulinum toxin when used in a medical setting as an injectable form prevent the release of a chemical known as acetylcholine by the nerve cells, which signal contraction of the muscles. By selectively interfering with the underlying tendency of the muscles to contract, the prevailing frown lines are smoothed out, and in the majority of the cases are almost invisible for a week.

What form does the radiation that is used to treat cancer take?
sergij07 [2.7K]

Answer:

Photon radiation

A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).

The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.
