All living organisms share characteristics such as DNA, the molecule that passes information between generations; metabolic proc
Naily [24]

Answer:

Biological evolution

Explanation:

<em>Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.</em>

There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.

The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.

Which description is true for both DNA and RNA molecules
GrogVix [38]

The correct answer is A.

Both DNA and RNA are types of nucleic acids.  DNA stands for deoxyribonucleic acid , while RNA stands for ribonucleic acid.

Both DNA and RNA carry genetic information. However,  DNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.

DNA is double stranded while RNA is single stranded.

DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.

Scientists observed that the populations of top-level consumers in a particular ecosystem were rapidly decreasing. Further studi
yanalaym [24]

Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.
