goldenfox [79]

Answer:

c. Tubulin

Explanation:

Tubulin protein is polymerized to form the cylindrical structures of microtubules. Microtubules form the spindle apparatus during cell division. The spindle microtubules become attached to the kinetochores of chromosomes and mediate the alignment of chromosomes at the equator of cells during metaphase. The shortening of spindle microtubules is responsible for the movement of sister chromatids during anaphase. The same event also moves the homologous chromosomes during anaphase-I.

Any failure in the formation of the spindle apparatus would not allow the proper separation of chromosomes. Therefore, the cell with abnormal chromosome separation might have a faulty or no tubulin.

Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

The food we eat
The environment we expose the cell to
The substances that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.

Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

What precautions need to be taken in order to euthanize mice by carbon dioxide inhalation while ensuring the least amount of str

Mekhanik [1.2K]

Be using a flow rate that moves 30% to 70% more volume through the cage or chamber each minute precautions need to be taken.

Inhale- To breathe in is to inhale. In contrast to "exhale," which is to breathe out, it is the reverse. Through our lips and nostrils, we take air into our lungs when we inhale, and breathe out again.

Lungs- The two spongy, pinkish-gray organs in our chest are our lungs. Air enters our lungs during inhalation, and oxygen from that air travels to our blood during breathing. Additionally, a waste gas called carbon dioxide travels from the blood to the lungs where it is expelled.
