Answer:

A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.

Explanation:

Thanks OP for answering your own question!

The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.

Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

➜ Speciation is the formation of new species from the pre-existing population.

Factors responsible for speciation:

Geographical isolation cannot be a major factor in the speciation of a self-pollinating plant species because physical barrier cannot be created in self-pollinating plants.

Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

Answer-

The plants stomata!

Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals. In optimum conditions, stomata are wide open, allowing gaseous exchange with the atmosphere.

their fur is that color so they can camoflaugue with their surroundings

Answer:

Because God put them there on purpose. For example, they could hide in little tunnels in the ground to hide from predators, and also, so it could camoflauge with it's surroundings. Have a great day!

➜ Mendel conducted breeding experiments with garden peas:

[i] He studied plants (pure) of a tall/short varities.

[ii] He crossed them and obtained F1 progeny.

[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[v] He found that in F2 progeny there were tall as well as short plants.

[vi] The three quarter plants were tall and one quarter was short.

(or any other contrasting character may be taken).

Note: Here, F1 means First fillial generation and F2 means Second fillial generation.

Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.

Answer:

Experiment

Explanation:

Scientific methods includes the step by step procedures in science of solving problems.

It has four basic steps this include, Characterizations which is the observations, definitions, and measurements of the subject that is involved in the research.

Hypotheses is formulated which is the theoretical explanations of the problems to be solved.

Predictions are made from the hypothesis formulated and

Experiments which is done to validate the hypothesis. It includes DAT collection, data analysis, interpretation of results. Nabeel is at the experiment stage where he is collecting data on plant and comparing the data so he can make inference that can help validate his hypothesis.

The diagram for this question is missing, but I'll try to solve it nonetheless, for PLATO users. I do believe the answer is Test the hypothesis with an investigation, at least when thinking of the guy up above me's answer....

Answer:

Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D

Explanation:

Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.

Answer:

It is A, They are all very reactive nonmetals with similar chemical properties.
