Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.
The right answer to this question is option A. Water moves in to dilute the sugar in the bear, causing it to swell.
That happens because there is a process involving water called osmosis. This process is pretty simple to understand. What happens is that the water will move from a place to another because of the concentration of solute. So, in this case, we have a higher concentration of solute inside the bear, and a lower one in the water, and for that, things need to be equal to reach the right balance between both concentrations. Once that happens, that water swells the gummy bear to balance these two them, and that's called osmosis.
Answer:
A
Explanation:
The correct option that does not describe the science of nutrition would be <u>that many studies have been conducted on the association between certain types of cancer and diet and, therefore, these links are well-understood</u>.
<em>While truly indeed many studies have been conducted linking certain types of cancer and diet, scientists are far from understanding the link between diets and cancer. While some degrees of understanding exists, it is not 100% certain that there is a cause-effect relationship between these two factors, and a large percentage of cases of cancer are caused by factors that cannot be controlled.</em>
The correct option is, therefore, A.
Answer: 16 possible stereoisomers

There a few correct ways. Each way is written in "binomial nomenclature" ; which is a form of taxonomy invented by Carl Linneaus that classified and identifiesan organism by two groups, using two separate words — in the order of:
______________________________________________________
1) the "genus" (in which the "first letter" of the word is ALWAYS in uppercase; and the rest of the word is ALWAYS in lowercase) ;
followed by a "space" ; and then:
2) the "species" — which is ALWAYS is "all lowercase letters ."

The following are correct ways to write the scientific name for the American black bear — in print.
______________________________________________________
1) <span><em>Ursus </em> <em>americanus</em> . {This is the preferred method).
{ Note: Each word is in italics. There is no additional "bold font" or "underlining" .}.
</span>______________________________________________________
2) <span><u>Ursus</u> <u>americanus</u> <u></u>.
{ Note: Each word is underlined separately.
</span> There is no additonal "bold font" or "italics" .} .
______________________________________________________
3) Ursus <span>americanus </span>.
{ Note: This is all in bold font—no "italics" or "underlining" .}.
