I believe he is looking for an allele
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosomes. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
Answer:
hope it helps
Explanation:
1) antibiotic drugs can kill bacteria however, they are not effective against viruses
2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells
The flow of energy moves through living organisms via the food chain. A food chain is a diagram which shows how every living thing gets energy to live. Plants use the sun, nutrients in the soil and water to generate energy. Herbivores eat the plants to generate energy to survive. Carnivores eat the herbivores to generate energy.
<span>Matter moves through the biosphere by being cycled through various organic and inorganic stages. They are neither created nor destroyed. The biosphere is known as a closed system so no elements can escape. They are continually being recycled.<span>

The answer is a start codon. An open reading frame is a region of DNA with a span of nucleotides beginning with a start codon (usually ATG) and ends with a stop codon (usually, TGA, TAG, TAA). An open reading frame when translated, codes for a full functional protein hence can be used to predict genes.
The answer is letter B.

Viruses have the ability to reproduce on their own and
sometimes within hosts. It is an infectious agent that can affect all types of
life forms (e.g. animals, plants, microorganisms). They are found in almost
every ecosystem on Earth and they are the most abundant type of biological
identity. Asvirology is the study of
viruses which is a sub-specialty of microbiology. The spread in many ways and
can be transmitted from one organism to another or sometimes to multiple
organisms at the same time. Its origins in the evolutionary history of life is
still unclear but they are considered to be life forms because of their
capacity to carry genetic material, reproduce, and evolve through natural
selection. </span>
