Answer:
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances. Essentially, cohesion and adhesion are the "stickiness" that water molecules have for each other and for other substances. Credit: J. Schmidt, National Park Service
Explanation:
The correct answers are:
b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.
All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.
c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.
As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
Answer:
The correct answer would be 187-188 genes.
The chromosome is defined as a thread-like structure formed by deoxyribonucleic acid (DNA ) and associated proteins.
It carries the genetic information an organism in the form of genes.
Genes refer to the coding sequence of the chromosome which specifically codes for the amino acid sequence of a protein.
The genome of the yeast consists of 32 chromosomes which have 6000 protein-coding genes.
As these chromosomes are equal in size that is, each contains the equal length of the DNA.
Thus, hypothetically we can say that each chromosome consists of 187-188 chromosomes (6000/32 = 187.5)
There are generally three kinds of mutation.
1. Substitution
2. Deletion
3. Insertion
A substitution is change one nucleotide for another
A deletion is removing a nucleotide
An addition Is inserting a nucleotide
