The virus that causes mumps in humans is composed of a protein outer shell containing a core of DNA. The virus that causes the flu in humans is composed of a protein outer shell containing a core of RNA. Vaccines that are effective against mumps work efficiently year after year. Vaccines that work against the flu must be revised and changed every year. What accounts for the difference in the effectiveness of these two vaccines?

Answers

Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.

DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.

I agree with this person ^^

Explanation:

Which statement describes the relationship between chromosomes, genes, and alleles? A. Chromosome's have mutated parts called genes. These mutations are caused by alleles. B. Alleles are sites on a chromosome that genes bind to. C. Alleles transfer genes to the appropriate location within a chromosome. D. A chromosome's specific section is called a gene. Alleles are variations of a gene.

Answers

The relationship between chromosomes, genes and alleles is D. A specific part of the chromosome is a gene, and the alleles are different variations of the genes.

I think it's D! i haven't been in biology in a while sorry

Why do dead plants decompose slowly in marshes?

Teak, a highly prized tropical hardwood, is used extensively for outdoor furniture. Unfortunately, teak is grown in only a few locations throughout the world and native trees are becoming scarce due to repeated harvesting and the clear-cutting of forests. Logging teak forests disrupts the natural habitat of many other species and reduces local biodiversity. Foresters, seeking a reasonable solution to this problem, might consider ALL BUT

Answers

Answer:

The correct option is C. Growing farm crops in greenhouses instead of on land previously home to teak trees.

Explanation:

Teak is known to be the finest quality wood and is expensive. Naturally, it can take 40 years for a tree to produce the teak wood.

As it is the finest quality wood, scientists should try their best to replant the Teak trees.

Growing farm crops in greenhouses is an expensive method and also, it is not a reliable solution to the problem mentioned in the question. Hence, Option C is the answer.

Rest all options can increase the productivity of teak.

Answer:

C) growing farm crops in greenhouses instead of on land previously home to teak trees.
