Amoebiasis can be present with no, mild, or severe symptoms. Symptoms may include abdominal pain, diarrhea, or bloody diarrhea.
Answer: False
The variations in expression depends on how genes code for proteins
that would specify whether it will be dominant or recessive allele. Within a population, there may be a number of
alleles for a given gene and these differences
can cause variations in the protein that is produced. The change in protein
expression affect traits due to the variations in protein activity or
expression that produce different phenotypes.
<span>Moreover, individuals that have copies of
different alleles are known as heterozygous
and individuals that have two copies of the same
allele are referred to a homozygous. The expression patterns observed in
inheritance will depend on whether the allele is found on an autosomal
chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>
Answer:
(d). B-cells.
Explanation:
Adaptive immunity can be described as immunity which develops in response to exposure to a pathogen (or foreign molecule). throughout the life. It is divided into two types, humoral immunity and cell-mediated immunity.
Humoral immunity is mediated by B cells that secrete antibodies against particular antigens. These antibodies recognize and neutralize the antigens and activate cell-mediated immunity, which is mediated by T cells.
Thus, the correct answer is option (d).
