Answers

-refers to evolution at or below the species level- YES
- includes evolution at the population and community level - YES!
- analyzes the history of life over time - well, I wouldn't choose this answer. life.. as in one life form or all life forms? it's not clear to me. In any case "microevolution" doesn't anlyse anything, it's a process of change...
- refers to evolution above the species level -NO! it would be rather evolution within the same species, on a very small level
- is based on direct observation - NO! it would rather be based on genetic analysis

Answer:

Microevolution:

-includes evolution at the population and community level

-refers to evolution at or below the species level

As DNA is replicated, which DNA base pair will bond to cytosine ?

Answers

Answer:

Guanine.

Explanation:

DNA is present as genetic material of all the organism.DNA is made of the four different nitrogenous bases, pentose deoxyribose sugar and the phosphate group.

DNA is complimentary in nature in which the nitrogenous bases combine specifically with each other. Adenine binds with cytosine with two hydrogen bonds and guanine binds with cytosine with three hydrogen bonds.

Thus, the answer is guanine.

Adenine bonds with Thyamine Guanine bonds with Cytosine and vice-versa

In relation to natural gas, where is crude oil generally found? A.
Crude oil is found above natural gas reservoirs.

B.
Crude oil is found next to natural gas reservoirs.

C.
Crude oil is found below natural gas reservoirs.

D.
Crude oil is mixed in with natural gas reservoirs.

Answers

crude oil does not float over natural gas in the pore space of a reservoir rock. upon drilling of these energy sources, crude oil is much deeper than the natural gas. This means the answer to this problem would be C.

Answer: The correct answer is-

C. Crude oil is found below natural gas reservoirs.

Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.

Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.

Thus, option C) is the right answer.
