How is the secondary response different from the primary response in terms of antibody concentration in the blood? the secondary

response is faster, but does not produce more antibodies than the primary response. the secondary response is slower, but produces more antibodies than the primary response. the secondary response is faster and produces more antibodies than the primary response. there is no difference with regard to antibody concentration in the blood?

I believe the difference is that the secondary response is faster and produces more antibodies than the primary response. The primary immune response of the body to antigen occurs on the first occasion it is encountered, following this first exposure to a foreign antigen, a lag phase occurs in which no antibody is produced, but activated B cells are differentiating into plasma cells.The secondary response mediated by B cells with the help of T cells, produces high affinity and antigen specific antibodies.

What would happen if one of the chromosomes in a homologous pair failed to separate from its homologue at the end of metaphase I
Zepler [3.9K]

The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.

Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:  

• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),  

• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and

•  Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the labor
PSYCHO15rus [73]

A mutation is an alteration in the original DNA sequence.  Option 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material.

Mutations alter DNI sequences and introduce new variants. Many of these variants are eliminated, but some of them might succeed and be incorporated in each individual, affecting the entire species.

They can be damaging or beneficial. These last mutations are the ones that have been selected by natural selection.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level. They can change the bases sequences and bases pairing.

Mutations depend on each group's environment and its ecological pressures, and they accumulate in time. They are inherited to the followings generation and get to spread.

According to this framework, the correct option is 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

If the analyzed chemical is a mutagen, then it will cause an alteration in the DNA sequence and this change -mutation- will pass to the following generations spreading in the population.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in

the laboratory

Which statement best provides evidence that the substance is a mutagen?

  1. The cells die within hours of being exposed to the chemical.
  2. The cells grow more quickly than those that were not exposed to the chemical.
  3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
  4. The cells continue to divide at the same rate as before they were exposed to the chemical.
