Answer:

Botulinum

Explanation:

Botox is used cosmetically to remove wrinkles and to treat certain muscular conditions. It is made from Botulinum neurotoxin obtained from the bacteria <em>Clostridium botulinum</em>. It is a very powerful neurotoxin but in Botox procedure it is used in extremely small concentration so it does not cause harmful effects. Botox process usually lasts for four to six months.

Botulinum acts as acetylcholine antagonist and inhibits the release of acetycholine neurotransmitter at the neuromuscular junction. This inhibits the signalling between motor neurons and facial muscles. As a result, the facial muscles are not able to contract and hence wrinkles are not formed on skin.

Answer;

-Botulin

Explanation;

Botox injections smooth facial wrinkles because botulin is an ACh antagonist that blocks the underlying facial muscles.

-Botox injections are the best known of a group of medications that use various forms of botulinum toxin to temporarily paralyze muscle activity. This toxin is produced by the microbe that causes botulism, a type of food poisoning.

-These botox injections have the ability to reduce the appearance of some facial wrinkles. They are also used to treat such problems as repetitive neck spasms, excessive sweating, overactive bladder and lazy eye.

-Botulinum toxin acts by binding presynaptically to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect.

Answer:

Capsule

Explanation:

In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.

The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.

In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.

Thus, the capsule is correct.

vlabodo [156]

Answer:

The answer is A

Explanation:

There are certain types of proteins that need to be sinthesized in the rough ERC in order to reach its final destination. These proteins are:

- Proteins that need to be exported from the cell.

- Proteins that need to be docked to either endomembranes or the plasma membrane.

- Hydrolytic lysosomal enzimes.

- Proteins that have a function in the lumen of certain organelles such as the endoplasmic reticulum, golgi or the nuclear envelope.

Hemoglobin doesn't fit in any of these cateogories, given that it is a cytoplasmic protein. Therefore, its synthesis begins and ends in the cytoplasm, where the protein performs its function.
