Answer:

All the cells present in the body receive and respond to signals. There are three signaling pathway endocrine signaling, paracrine signaling, and autocrine signaling through which cells receive the signals.

In endocrine signaling signal comes through blood, in paracrine signaling signals are released in extracellular fluid which reaches the cell present in close to it. In autocrine signaling, the same cell produces and receives the signals.

All cells have receptors that bind to the signal molecules and respond to the signals. These receptors can be extracellular or intracellular receptors. Extracellular receptors generally bind to hydrophilic molecules and intracellular receptor binds to lipophilic signal molecules.

This binding brings conformational change in the receptors which gives the signal to the cell to perform some function according to the signals provided. Thus this way all the cells respond to every signal.

Molecules that cannot cross the membrane bind to receptors in the membrane. When the signal binds to a receptor changes it's shape. Other Molecules inside the cell respond to the chainging shape of the receptor.

The scientific name of the sugar maple is Acer saccharum. What does each part of the name designate?
irinina [24]

Answer:Acer represents the genus name while

saccharum represents the species.

Explanation:

In a way to classify organisms, biologists used certain important common features to structure them into groups. The arrangement of living organisms in this hierarchy from the highest level to the lowest is as follows:

Kingdom--> phylum-->class-->order--> Family-->genus--> species.

The largest group of organisms is kingdom while species is the smallest unit of classification.

The common name of the plant used in the question above is sugar maple. Biologist, however, use a standard system to name living organisms. Each kind of organism is given two names, hence the term BINOMIAL NOMENCLATURE.

--> The first name is the name of the genus to which the organism belongs.

--> The second name is the name of the species to which it belongs.

Both names are printed in italics with only the genus name having an initial capital letter. Hence, the scientific name of sugar maple is Acer saccharum( in italics).

White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.

Explanation:

Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.

He was also awarded by the Nobel prize for his works which was related to medicine in 1933.  He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.
