Answer:
The probability will be 25% (1/4)
Explanation:
Schilder's syndrome is a degenerative and progressive lethal disease caused by the demyelination of nerve cells in the brain and spinal cord. Since it is a lethal recessive autosomal disease, both the father and the mother have a single copy of the mutant allele, thereby the probability of obtaining a lethal combination will be:
SN X SN >>
1/2 x 1/2 = 1/4 = 25%
where N and S are normal and lethal alleles, respectivelyvely
The correct option are as follows:
cholera is a bacterial infection of the small intestine.
vaccination provides protection against cholera.
the cholera vaccine is made up of a weakened form of the bacteria that causes cholera.
the vaccine will stimulate production and elicit an immune response.
- If the infection occurs again, the body will produce an even greater attack on the bacteria because of acquired immunity.
- By injecting a heat-killed, weakened organism or its component (antigen) into the body, vaccination aids in the development of immunity. Memory cells and antibodies are produced as a result.
- Memory cells aid in the development of immunological memory, which helps the immune system to respond to microorganisms that the body has previously encountered with greater strength and efficiency during a secondary immune response.
- Memory B cells and memory T cells aid in the development of immunological memory.

The ATP is then used throughout the cell and through the body for all of its needs. Carbon atom starts out in photosynthesis as part of a carbon dioxide molecule. Carbon dioxide is broken down into oxygen and carbon.
