Sexual reproduction is one type of biological reproduction wherein the genitals of the male and female organisms engage into a sexual activity in order for the sperm cells to fertilize the egg cells of the females.
In the case of most plants, they engage in asexual reproduction. Asexual reproduction happens outside the body system of a cell.
Moreover, this process is extrinsic than its opposite the sexual reproduction which happens in the female reproductive system.
Answer:
What are DNA vaccines? - Biologybiology.kenyon.edu
Explanation:
DNA vaccines are third generation vaccines. They contain DNA that codes for specific proteins (antigens) from a pathogen. The DNA is injected into the body and taken up by cells, whose normal metabolic processes synthesize proteins based on the genetic code in the plasma that they have taken up.
Answer:
Type IIA- Fast twitch, fatigue resistant unit
Explanation:
During intense activities such as exercises where there is an increase in the contractile muscle strength, there is an activation of additional muscles to accomplish the task.
This is referred as motor unit recruitment.
It can be type I where it involves slow twitch fatigue resistant units with small twitch tension and slowest contraction
Or Type II A- where fast twitch, fatigue resistant fibers are activated to enable a larger force and faster contraction.
They help to protect us against invading pathogens. You have beneficial bacteria growing on your skin, in your bowel and other places in the body (such as the mouth and the gut) that stop other harmful bacteria from taking over.
