Answer:
That’s an interesting question
Explanation:
Huh let’s think???
Viruses are at the heart of this century-old debate. Viruses<span> are parasites that infect plants, animals, fungi and bacteria. They consist of genetic material surrounded by a protein coat and are unable to grow or reproduce without a host. The classification of viruses has confused scientists for nearly 100 years. Originally they were viewed as poisons. In fact, the word ''virus'' is Latin for ''poison.'' They have since been viewed as living creatures, then mere bio-chemical compounds, and, most recently, somewhere in between chemical compounds and lifeforms.</span>Non-cellular life<span> refers to organisms, such as viruses, that exist without any cells, and it is a very controversial topic. The cell theory, which is one of the fundamental tenets of biology, states that all living things are composed of cells and that cells are the basic units of life. So the idea that something can be considered alive without having cells is an issue that is up for debate.

Answer:
b. Clostridium botulinum.
Explanation:
The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells Moreover, <em>Clostridium botulinum </em>is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.
The superficial palmar arch<span> is formed predominantly by the </span>ulnar artery<span>, with a contribution from the </span>superficial palmar branch of the radial artery<span>. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the </span>princeps pollicis artery<span>, the </span>radialis indicis artery<span>, or the </span>median artery<span>, the former two of which are branches from the radial artery.</span>
