Why is it important to use a weakened virus in a vaccine?
PolarNik [594]

If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.

Viruses in vaccines are weakened, so they essentially will not "fight" back. They most importantly just contains the antigen markers so the body can trigger the immune response, quickly eradicate the pathogen, and build up the memory cells to that virus.

Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.

If you have a heterozygous yellow-seed plant (Yy), the probability of forming a "Y" gamete is blank. The probability of forming
hram777 [196]

Answer:

<em>The probability of forming a "Y" gamete is 50%. The probability of forming a "y" gamete is 50%.</em>

Explanation:

Mendel was an Austrian monk whose findings led to make the foundation of genetics. Hence, Mendel is known as the father of genetics. He formulated two laws based on the researches he made:

  • Law of segregation
  • Law of independent assortment

According to the law of segregation, alleles segregate independently at the time of gamete formation. There is an equal chance for a gamete to carry the dominant or the recessive allele.

Hence, the probability of a gamete carrying a 'Y' or a 'y" allele will be 50% each.

Describe the connection between glycerol, fatty acids and triglycerides.
Leya [2.2K]
<h2>Answer:</h2>

<h3>In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.</h3>

Create an analogy of the Respiratory System to compare it with a non-living system.
alisha [4.7K]
An analogy that can link with the process of respiration can be a factory. For example, the way that the factory processes raw goods to make manufactured goods is similar to how the respiratory system takes in molecules and breaks it down into energy.
