Creating hypotheses based on observations.A hypothesis is a general principle or explanation that is derived from observations.

Suppose you make the following observations: a. You look at 10 human liver cells and observe that each one has a nucleus. b. You look at 10 onion cells and observe that each one has a nucleus. c. You look at 10 nerve cells from a mouse and observe that each one has a nucleus.For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.1. The onion cells I looked at have a nucleus. F?2. All onion cells have a nucleus. T?3. All cells have a nucleus. T?4. Some cells have a nucleus. T?5. Only onion cells have a nucleus. T?6. If I look at 10 skin cells from my hand, each one will have a nucleus. T?

Answer:

  1. False
  2. True
  3. True
  4. False
  5. False
  6. True

Explanation:

A hypothesis is a supposition draw from data to carry an investigation or an argumentation.

1. The onion cells I looked at have a nucleus. False, even though the statement is true, is not a hypothesis because is not a supposition, it is rather an observation.

2. All onion cells have a nucleus. True, it is s a <u>valid hypothesis</u> because after the observation of 10 cells you draw a conclusion or supposition and affirm that all onion cells have a nucleus.

3. All cells have a nucleus. True, it is a<u> valid hypothesis</u> it contains a supposition derived from data observation

4. Some cells have a nucleus. False, the hypothesis is not valid because all of the observed cells contained nucleus not only some of them.

5. Only onion cells have a nucleus. False, after the observation of the different type of cells you see that they all had nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus. True, after the observation of different cells you can infer that if you look at your skin cells, they will have a nucleus.

How did early humans survive without clothes?
blsea [12.9K]
Of course we can survive without clothes. We evolved a hairless body because our ancestor was an ape that was forced to live in the hot, open savanna, where fur is not needed. In fact, many people around the world did not wear any clothes. Native Hawaiians, for example, wore no clothes when the first European explorers arrived. Amazonians and Africans also did not wear clothes. Humans evolved in Africa about 150,000 years ago, and the early humans wore no clothes. Humans started migrating out of Africa about 60,000 to 70,000 years ago. They followed the coast line and went all the way to Australia. These early migrants ended up in places that required no clothes. Only when humans migrated to places like ice age Europe and northern parts of Asia (northern parts of China, Japan and Korea) did they need to wear clothes or animal skins to stay warm. Wearing clothes blocks out the sun and these people were in danger of vitamin D deficiency, which leads to rickets. Rickets can result in muscle cramps, broken or deformed bones and even death. In order to absorb enough UV light to synthesize vitamin D, there was strong selection pressure to evolve lighter skin tones.

The habit of wearing clothes, even in places that do not require them, was spread by European Christians. Basically they forced and/or shamed the natives to wear clothes wherever they went.Of course, not wearing clothes means that humans will no longer be able to live in temperate areas around the world, at least not during the fall and winter months.

Protein X is a protein that is composed of four subunits of equal size--alpha, beta, delta, and gamma--that are bound by either
alexandr402 [8]

Answer:

The correct answer is e3

Explanation:

The given protein in the question proteib X contain four subunits of equal size alpha,beta,delta and gamma which are bound by either noncovalent interactions or disulfide bridges and only beta and delta subunits are bound to each other by disulfide bridges.

  As a result when the protein will undergo fragmentation it will generate 3 bands because the interaction that is present between alpha and beta subunit will break resulting in the formation of 2 bands. Now the most important fact is that the beta subunit is linked to delta subunit by di sulfide bond so when betamarcaptoethanol will act on protein X it will break the disulsulfide bond present between the beta and delta subunit to reduce both the subunit.

  Finally the interaction that is present between delta subunit and gamma subunit will be broken down to release the delta subunit which will form a single band during SDS PAGE..

Anna007 [38]
<h2>Alcoholic Fermentation</h2>

Explanation:

  • Two attributes of regular wines are that they have a most maximum alcohol content of 14% and are "sparkling" wines.
  • In natural wines, after the ethyl alcohol and are <em>"shimmering" wines. </em>
  • <em>In regular wines, after the ethyl liquor fixation arrives at 14%, the liquor murders the yeast cells, making aging stop. The bubble or shimmer in wines is the collection of CO2. </em>
  • Yeast keep on aging sugars until they either come up short on nourishment or the liquor content gets sufficiently high to slaughter them.
  • The  most wine yeasts, 14% is higher than they can tolerate. There are, be that as it may, yeasts that the merchants<em> guarantee can tolerate higher alcoholic rates.</em>
