Answer:

Microfilaments, Intermediate filaments and microtubules

Explanation:

Three distinct elements make up the cytoskeleton in eukaryotic cells are:

1. Microfilaments or actin filaments which are composed of actin proteins. The functions of those filaments are: muscle contraction (myosin heads move “walk” on actin filaments), the movement of the cell, intracellular transport, maintaince of the cell shape..

2. Intermediate filaments which can be made of vimentins, keratin, lamin, desmin… Their functions are: the maintenance of cell shape, anchoring organelles, structural components of the nuclear lamina, cell-cell and cell-matrix junctions…

3. Microtubules are filaments polymers of alpha and beta tubulin. Their roles are in intracellular transport (associated with motor protein dyneins and kinesins), formation of the axoneme of cilia and flagella, formation of the mitotic spindle.

Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags

olga2289 [7]

Answer:

See the answer below

Explanation:

From the illustration of the experiment, the question that Carson can best answer is that<em> "Do bananas develop more brown spots if they are kept in bags with holes compared to bags without holes?"</em>

The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.

<u>Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes. </u>

A client on the psychiatric unit sits alone most of the day. the nurse approaches the client. as the nurse gets approximately 3

puteri [66]

Since the client is throwing tantrums and outburst, it is best to calm the client but taking an action of having to talk to him or her or try to get closer to him or her will likely provoke him or her into doing what he or she is currently doing. It is best for the nurse to calm the client by having to tell him or her that the nurse will leave and will be back as soon as he or she calms down.

Answer:

Advantage

Explanation:

It all comes down to a process called gene regulation. This is how our genes are turned off and on, for minor things like hair color and vital functions like protection from cancer. Within our bodies, we house trillions of cells, all busily going about doing their jobs while we enjoy our days
