How do older female killer whales help their family​

Biology
1 answer:
jeka943 years ago

Answer:

Senior mothers are also under pressure to share food with their sons, so that they're able to reproduce as well. It also makes sense for these mothers to assist their sons because as the mothers grow older, they are increasingly related to whales in other, neighboring pods via their sons' calves.

Infection occurs when the host is exposed to pathogens. what type of pathogen uses the cell's metabolism, and replicates itself
vladimir1956 [14]

Answer: Infection occurs when the host is exposed to pathogens. virus uses the cell's metabolism, and replicates itself while destroying the cell or changing the cell's genetic makeup.

Explanation:

  • A virus is a miniscule pocket of protein that contains genetic material.
  • Viruses pose a considerable challenge to the body’s immune system because they hide inside cells.
  • This makes it difficult for antibodies to reach them. Some special immune system cells, called T-lymphocytes, can recognise and kill cells containing viruses, since the surface of infected cells is changed when the virus begins to multiply.
  • Many viruses, when released from infected cells, will be effectively knocked out by antibodies that have been produced in response to infection or previous immunisation.
  • Antibiotics are useless against viral infections.  So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.

Hence virus are the pathogen that use the cell's metabolism. And replicate itself while destroying the cell or changing the cell's genetic makeup. viruses are so simple that they use their host cells to perform their activities for them

mixas84 [53]

Screening someone's blood and the biomolecular revolution would not have been possible without the human genome project.

<h3>The human genome project</h3>

The human genome project was initiated around 1990 with the aim to obtain the sequence of genes in an individual. It seeks to obtain the accurate arrangement of DNA in human beings.

<h3>Impact of the human genome project</h3>

The human genome project has made it possible to study all the genes in human beings and made us able to have a better view of biomolecular science.

Hence, screening someone's blood and the biomolecular revolution would not have been possible without the human genome project.
