Answer:

Your answer would be a autosomal dominant disorder.

____________________________________________________

Definition:

Autosomal Dominant Disorder:

A disorder in which could pass a disease from generations and on. In other words, future generations "inherit" the disease

____________________________________________________

Explanation:

The reason why "autosomal dominant disorder" is the correct answer because when a disease has been going on for many generations, this would be known as an autosomal dominant disorder, or ADD. What this means is that a person could have a mutant gene in them, also having a normal gene that is paired with  autosomal chromosomes. These diseases are inherited from a off spring that could take the disease and pass it on to their off springs, which would go on for generations due to the fact that it is a "dominant" trait. This is similar to the autosomal recessive disorder, but the autosomal recessive disorder needs two mutant genes in them, meaning that there is a less likely chance of getting the disease passed on to the off spring. The autosomal dominant disorder only needs one mutant gene in order to be effective during the inheritance for a offspring.

STatiana [176]

Answer:

The given blanks can be filled with white pulp and red pulp.

Explanation:

In the lymphatic system, the spleen is considered as the largest organ. It is situated in the upper left part of the abdominal cavity, the main function of the spleen is to filter blood containing the destructed cells, pathogens like viruses and bacteria, and cellular debris.  

The spleen generates and develops the mature immune cells, which possess the tendency of finding and eliminating the pathogens. The white pulp of the spleen comprises the immune cells, that is, the B and T lymphocytes, which help in fighting against the pathogens.  

On the other hand, the red pulp of the spleen comprises connective tissue called the cords of Billroth, and various splenic sinusoids, which are filled with blood, providing it a red appearance. Its main function is to filter the blood containing microbes, pathogens, and worn-out or the defective RBCs.
