ddd [48]3 years ago
4 0

Answer:

See the answer below

Explanation:

In science, research questions are generally derived from the observation of phenomena. Also, hypotheses that represent general statements that have not been tested are formulated in such a way that they can be falsified. Hence, for each of the observations in the illustration, the question and their respective hypothesis would be as follows:

1. Observation: a teenager observed that he had three new pimples the night after eating a chocolate bar.

Question:  Do chocolate bars cause pimples in teenagers?

Hypothesis: If teenagers eat chocolate bars, they might get pimples.

2. See the attached image

3. Observation: A little boy observed the leaves on trees changed colors when the temperature was lower.

Question:  Do lower temperatures cause tree leaves to change color?

Hypothesis: If the ambient temperatures of trees are lowered, their leaves might change color.

belka [17]

Answer:

See explanation

Explanation:

There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.

Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.

How are alleles for the same gene related? A. They have different genetic sequences but are found in the same location on a chro
Dmitrij [34]

Answer:

A. They have different genetic sequences but are found in the same location on a chromosome.

Explanation:

In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.

Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
