Answer:
The influenza virus has a negative sense RNA genome. In order to replicate, this means that the virus must first produce positive sense mRNA in order to produce necessary enzymes. Once the enzymes are translated, replication can take place. Positive sense cRNA is then made from the original negative sense RNA, using the enzymes. Negative sense RNA progeny are then made from the positive sense cRNA. The final viral progeny eventually bud from the host cell, ready to infect other cells.
Explanation:
High blood levels of the amino acid homocysteine
have been linked to increased risks of cardiovascular disease.
<span>Cardiovascular disease is a disease related
to heart, in which vessels become narrowed or blocked and these can lead to
heart attack or stroke.
Homocysteine is an amino acid and its important source
is meat, we get this from eating meat and when the level of these amino acid
increases in the blood, it leads to heart disease.</span>
Answer:
d. an extensive surface area well suited for invasive growth and absorptive nutrition.
Explanation:
Fungi have an extracellular nutrition. These means enzymes are released to environment to start degrading macromolecules which can be later be absorbed (absorptive nutrition) through cell membranes. Having multiple spots (bigger surface area) through which it can nurture speeds up the rate at which it can grow leading to a faster growth and higher competition over resources.
