Anastasy [175]

Answer:HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

Do either of your diseases in part A have the same pattern of inheritance as the model colorblindness mutation you made?How do y
Alborosie

Answer:

Autosomal dominant pattern.

Explanation:

If the pattern of inheritance is same in the disease just like the model of colorblindness mutation so we can say that the disease has autosomal dominant pattern because the colorblindness mutation also occur due to the autosomal dominant pattern. Sometimes the disease is also inherited from their parents through genetically. So both diseases and the model colorblindness mutation are considered same if both have the same pattern of inheritance.

Prophase I
The chromosomes condense, and the nuclear envelope breaks down & crossing-over occurs.

Metaphase I
Pairs of homologous chromosomes move to the equator of the cell.

Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.


Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.

Prophase II
A new spidle forms around the chromosomes.

Metaphase II
Chromosomes line up at the equator.

Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.

Telophase II and Cytokinesis
A nuclear envelope forms around each set of chromosomes & the cytoplasm divides.

How do contractile vacuoles help amoebas maintain homeostasis?
givi [52]
Single celled organisms such as amoebas, especially those that live in fresh water, continually gain water from their surrounding environment by osmosis. This water is pumped into a contractile vacuole which fills with fluid and periodically fuses with the cell membrane, releasing its contents to the exterior. Thus the amount of water actively transported out of the cell is equal to the amount of water entering the cell due to osmosis and there are no variations in the tonicity of the cell. This is homeostasis at a simple level. Without the contractile vacuole, the amoeba would continue to absorb water until its cytoplasmic contents were diluted to such an extent that metabolism no longer occurred and it would die.
