Answer:

Rats have same physiology, similar organs and similar body plans just like humans.

Explanation:

Brown rats experience similar genetic diseases as humans because of same physiology, similar organs, similar body plans and also belongs to similar group of mammals. Due to these similar physiology, organs and body structure, the rats also experience similar genetic diseases just like humans. So that's why Scientists chose brown rats to study genetic diseases occur in humans.

How might you be able to tell the difference between mitotic and interphase cells?
Maslowich

Answer:

A visible chromosomal material in mitotic cells as opposed to the invisible chromatin material in Interphase cells

Explanation:

The cell cycle of a cell involves all activities that leads to its division. The cell cycle is majorly encompassed by the INTERPHASE and MITOTIC PHASE. These two phases are two distinct phases of the cell cycle.

The Interphase is the phase where the cell undergoes rest and preparation for the next round of division (mitosis). Hence, a cell at the Interphase stage is said to be an Interphase cell. On the other hand, the Mitotic phase is the phase where the actual division takes place i.e. both nuclear (mitosis) and cytoplasmic (cytokinesis) divisions. A cell at the mitotic phase is said to be a mitotic cell.

The major distinguishing factor between a cell at the Interphase stage and a cell at the mitotic stage is that the chromosome (nuclear material) becomes visible when the cell enters mitotic phase. This is due to the condensation that the Chromatin material, which is the found state of the nuclear material in Interphase, undergoes in Prophase of Mitosis (first stage of mitosis).

mixas84 [53]
For the first question, i think the correct answer is A. Normal cells undergo apoptosis while cancer cells don't. For the second question, The answer is option B.<span> </span><span>Cell division has two checkpoints namely, G1 checkpoint and spindle assembly checkpoint. The checkpoint which determines if division has properly occurred is the G1 checkpoint. At this point, is a damage in the DNA is detected or the has not reach the optimum size, the cell is stopped in G1 and is not allowed to proceed to further process.</span>

Which feature contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell?
shutvik [7]

Answer:

In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).
