Natural selection favors pathogens with

Answers

Answer 1

Answer: The answer is a drug-resistance.

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. The drug resistance is the trait that increases the chance of bacterial survival and reproduction.Thus, if there are pathogens with drug-resistance and pathogens without drug-resistance, then natural selection will favor those pathogens that are drug resistant.

In this lab, you will explore the microscopic process of building proteins from RNA. Instead of working with variables, you will focus on the steps of that process. What investigative question will you answer by exploring this process?

Answers

The investigative question that would focus on the steps of the process of exploring the microscopic building of proteins from RNA would start with a 'how'. This is because how questions ask about the process. For example, 'How are proteins built from RNA?' would be a good investigative question.

Answer:

theses are several answers.

1. How are proteins built using the information provided by a molecule of RNA?

2. How are the processes of transcription and translation used to create proteins?

3. What are the steps that occur within the cell to build proteins?

What may happen to a species whose limited habitat is destroyed by land development

Answers

Answer:

extinct

Explanation:

The practice of land development like the urbanization and industrialization which leads to rapid and heavy use of the natural resources of the lands and thereby creates pressure on the biological diversity of the lands and thus making it difficult or the survival of the species.

The land development practices of the agriculture that leads to the introduction of new species of flora and fauna create a competition of the native species and thus decrease there chances of survival and loss of habitat hence create extinction of the species.

it will become extinct
