Answer: Infectious virus
Explanation:
This is because it spreads widely from one person to another from contact
Cells are the basic unit of structure and function of all living things.
All cells come from other cells.
All cells come from nonliving matter.
Cells make up most organisms, but not all.
The first 3 are components, the others are not.
B. The internal structures provide shape and support to a variety of living organisms-both unicellular and multicellular.
C. They help scientist classify all living organisms by the types of cells they are made of.
D. The combination of chemical functions and genetic material enable the cell and the organism to live,grow,and reproduce.
B. Men and women all over the world have investigated scientific questions throughout history.
C. All useful scientific knowledge has developed within the past 100 years.
D. No new discoveries are left to be made.
A is wrong, because that fact just simply is not true. There have been several other raced men and some women as well that made important contributions to science.
B is correct, because science isn't attributable to just the last couple of hundred years. In ancient times, people developed astronomy and medicine. This is also correct because it names females as part of the scientific contributions to society.
C is incorrect, because this fact is also completely false. Lots of important scientific discoveries have been made from before that, such as the invention of electricity (somewhat useful today I would guess :\ ) in 1879, which is much longer than 100 years ago.
D is also incorrect, because scientific knowledge is changing constantly, every minute, growing and expanding and changing to accomodate new knowledge and information that we've discovered.
Biological science has developed over time through the contributions of both men and women from different backgrounds and cultures.
B. Men and women all over the world have investigated scientific questions throughout history.
Biological science has developed over time through the contributions of both men and women from different backgrounds and cultures. For example, ancient civilizations like the Egyptians and Greeks made significant contributions to biological knowledge, such as the discovery of human anatomy and classification of organisms. This trend of diverse contributions continued throughout history and is still evident today.
By recognizing the contributions of individuals from different genders, races, and cultures, we can appreciate the rich history and ongoing development of biological science.

B) nitrogen fixation
C) genetic variation.
D) genetic engineering.
Antibiotic resistance in bacteria is the result of genetic variation.
DNA sequence variations among members of a population are referred to as genetic variation. Sperm and egg cells, as well as somatic (all other) cells, are subject to variation.
Only variation that develops in germ cells can be passed from person to person and hence influence population dynamics and, in turn, evolution.
Genetic variety first appeared as a result of mutations. A mutation is a type of DNA sequence change that is permanent. When a mistake in DNA replication occurs and is not fixed by DNA repair enzymes, de novo (new) mutations take place.
Therefore, Antibiotic resistance in bacteria is the result of genetic variation.
