Answer:
(d) The parasite is transferred inside the body of a healthy person along with the mosquito bite.
The answer is :
B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell.
The DNA has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.
Explanation:
The nucleus is a membrane-enclosed organelle located in most eukaryotic cells. The nucleus is the largest organelle in the cell and includes most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it proceeds up just a small portion of the cell's overall DNA content. Inside its fully enclosed nuclear membrane, it contains the preponderance of the cell's hereditary material. This material is designed as DNA molecules, along with a family of proteins, to form chromosomes.
Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
Uh, can you be more specific? Theory and belief of what?
