Answer:

What can be deduced of cell that have densely packed mitochondria and the cristae are very closely together is that its function requires large amounts of energy.

Explanation:

Mitochondria are cellular organelles in charge of energy production. In these organelles occurs oxidative phosphorylation and electron transport chain, whose final product is ATP, an energy molecule.

A <u>cell with a large number of mitochondria, whose crests are very close together and tight, belongs to a tissue that has a lot of activity and its energy requirement is high</u>.

An example of cells with densely packed mitochondria are skeletal muscle and heart muscle.

-Dominant- [34]

Answer:

Ralph is looking at a vein (likely a muscular vein).

Explanation:

Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves.  This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.

Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.

mihalych1998 [28]

Answer:

Option-A

Explanation:

RhoA is a protein which belongs to the Rho GTPase family proteins and related Ras superfamily. The Rho A protein is involved in the cell division before the cytokinesis as they are involved in the formation of cytokinesis structures like the actin-myosin rings and the contractile ring formation.

In the given question, if the drug inhibits the activity of RhoA, therefore, cytokinesis will be affected and the cell will complete all the stages of Mitosis except cytokinesis. The cells will be mostly observed in the telophase as cytokinesis will take place after that.

Thus, Option-A is correct.
