Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true

  • Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
  • The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

Answer:

The smallest size tube that will hold the entire reaction is 0.5ml

Explanation:

25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total

since 1000ul=1ml, then 500ul = 0.5ml

Answer:

The device that mostlikely would not be used P20

Explanation:

P20 is a pipette used to measure and sample volumes of 20ul maximum.

Answer:

The reaction mix will have 400 units of the enzyme.

The working dilution will be 0.8 Units/ul.

Explanation:

The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.

Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.
