<h3>What are Fungi?</h3>

Fungi is a separate kingdom of the five kingdom classification. A fungus is any member of the eukaryotic organisms which includes microorganisms such as yeasts and molds, as well as the mushrooms.

Fungi are the eukaryotic, non-vascular, non-motile, and heterotrophic organisms. Fungi may be unicellular or filamentous. Fungi reproduce through the means of spore formation. Fungi exhibit the phenomenon of alternation of generation. Fungi lack chlorophyll pigment and hence cannot perform photosynthesis like plants.

Therefore, the correct option is C.

Which best describes the role of an immunosuppressant in a transplant surgery
pickupchik [31]

Answer:

When an organ is transplanted in the body, the immune system will attack the organ as it would attack any foreign cell. The use of it in transplant surgeries decreases the strength of the immune system by reducing its antibody production in order to reduce its attacks on the new organ.

Similarities between humans and snails.
Gennadij [26K]

Answer:

Explanation:

Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.

The finding, reported online in advance of publication in Nature by University of California, Berkeley, researchers, indicates that the same genes have been responsible for establishing the left-right asymmetry of animals for 500-650 million years, originating in the last common ancestor of all animals with bilateral body organization, creatures that include everything from worms to humans.

"Previous studies indicated that the methods for breaking left-right symmetry in animals seem to differ widely, so there was nothing suggesting that the common ancestor of humans, snails and other bilateral organisms had a common strategy for left-right asymmetry," said Nipam H. Patel, UC Berkeley professor of integrative biology and of molecular and cell biology, and an investigator of the Howard Hughes Medical Institute.

Which of the following conclusions can be drawn from this graph?
azamat

Answer:

A

Explanation:

We can't see the graph, but I think I found the worksheet online, and so the graph is attached.

The answer cannot be B, as we are looking at a graph of pH, not temperatures. Therefore, we cannot draw this conclusion

The answer cannot be C, as pepsin is a digestive enzyme, and it works best at pH of around 2.

The answer cannot be D, because we can see that arginase and salivary amylase work at pH 7 and above, which is not acidic

The answer is A, because the lines for each enzyme are different, each peaking at a different pH. These peaks represent their optimum temperatures, and the hills of the peak represent the range in which they can work
