Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host (and the cells within the host) that can be infected by a particular virus.
Explanation:
Answer:
The enzyme function best at a specific temperature.
Explanation:
Enzyme activity is affected by temperature. Each enzyme has a specific temperature
range in which it works most effectively. Most biological enzymes present in the human body have an ideal temperature range of around 98.6 degrees.
A)A chromosome is a long continuous strand of DNA
Answer:
The next step would be the bottom left corner.
Explanation:
This phase is called Anaphase 1.

The F1 generation differed from the F2 in the Mendel's experiments in that all the F1 generation showed the dominant phenotype, however only three- fourths or three quarters of the F2 generation did. This is because all the F1 generation were heterozygous and thus the dominant phenotype was expressed, while in the F2 generation there was a mixture of homozygous dominant, homozygous recessive and heterozygous. Therefore, the heterozygotes and the homozygotes dominant showed a dominant phenotype.
