While doing research on deep-sea vents, you discover a very simple new life form. After some initial analysis, you find that thi

s life form contains small fragments of DNA, small complementary RNA fragments, and proteins. Fortuitously, you collected two strains, one that is purple and one that is yellow. You decide to attempt a transformation: seeing if you can covert the purple form into the yellow form. From which sample(s) would you find some yellow form

Answer:

The yellow form can exist in both the "live yellow" and "heat-killed purple" forms.

Explanation:

To carry out these transformation tests; for example change of purple structure form into the yellow structure; DNA, RNA, and proteins will be confined from the yellow structure and infused to heat-killed purple structure each in turn in singular examinations. At the point when DNA will be changed into heat-killed purple structure form, it is changed over and converted to the yellow structure form. In this way, the yellow structure form can be acquired from live yellow just as heat-killed purple structure (changed with DNA or changing guideline from the yellow structure).

Answer:

A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.

Explanation:

Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.

  • <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>

Which structure has the least effect on the ability of a virus to infect and replicate in a host cell?
AleksAgata [21]
The answer is an envelope.

A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.

What is the savanna hypothesis? Group of answer choices Bipedalism was selectively favored because it helped our ancestors to st
Gnom [1K]

Answer:

Both options are valid, since in the hypothesis of the savanna it was argued that humans acquired bipedalism to be able to self-supply their food more effectively, and to have less body surface area exposed to the sun.

Explanation:

The saban hypothesis is believed to have originated in the saban, with the Austrolopitecus africanus being forced to affect this domain, which is why it acquired this adaptation mechanism.

The savanna had high grasslands, which also led to collaboration in this regard since they could be better camouflaged.

In addition, the human began to defend with the limbs of the upper limb, triggering the canines to decrease in size since it is not used as a defense mechanism.

The canine is a tooth that helps to tear carnivorous food, that is why the human also begins to have a more varied diet of fruits and seeds and that it can reach and take the bones of the tree to increase its height due to bipedalism.
