How does the immune system
produce memory cells for antigens?
This is the BEST research
question for students to ask if they are conducting research on antibodies
because t<span>he answer to this question must tell about
production of B-cells, recognition of antigen, T-helper cells, colony formation,
and phagocytosis of foreign antigen, T-killer cells, and all other details which
is possible.</span>
Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop
Answer: Option D
<u>Explanation:</u>
Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.
Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
The remaining ratio of alleles is about 3:1
<h3>What about alleles?</h3>
- The term "allele" is employed to refer to a gene's alternate form or variants.
- For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
- Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
- For instance, a dominant allele can overcome the characteristics of other recessive alleles;
- These features are what determine an individual's eye and hair color, for instance .
- In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
- Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
- Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
- Each gene during a human has two copies (or alleles), one from each parent.
- Alleles significantly contribute to the event of each person's unique traits.
- Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
- An allele may be a gene's variable form.
- Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
- Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.

I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.
One natural disaster has the ability to wipe out large crops and buildings that were used to fuel Earth's economy. It can also lead to a lack of biodiversity of an area that experienced the disaster.
For example, a tsunami can destroy buildings and kill an abundance of wildlife.
I hope I helped!
