Let us look at the what, why and how of studying extreme places like the deep earth and the deep space. Scientists need to figure out as to 'what' they want to look at such places, be it a new exotic creature or bio-genesis (birth of life). Unless there are several testable hypothesis constructed, such a study cannot begin. The 'why' aspect deals with the purpose of such research and expeditions. Is it of any use to the humans, or will it improve our current understanding of a phenomenon? The 'how' aspect deals with the technology and the economic assistance that can help in undertaking such a research. All these are the challenges that needed to be thoroughly considered to make such a research or expedition possible.

If a muscle fiber were to suddenly and permanently stop producing ATP the fiber would no longer be able to actively transport ca
Lyrx [107]

Answer:

A. Calcium would be transported to the sarcoplasmic reticulum therefore contractions would cease.

Explanation:

A muscle fibre will stop contraction immediately ATP is used up. Also, muscle contraction will end as soon as the information from the motor neuron stops. This repolarizes the sarcolemma and T-tubules, thereby closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are then pumped back into the sarcoplasmic reticulum, in order for tropomyosin to cover the binding sites on the actin strands again.

What is the primary function of carbohydrates attached to the exterior of cell membranes?
Alekssandra [29.7K]

Answer:

The correct option is : a. Identification of the cell

Explanation:

The cell membrane, also called plasma membrane, is a semi-permeable membrane surrounding the cytoplasm of the cell, that protects and separates the interior of the cells from the external environment.

The carbohydrate layer of the cell membrane is known as the glycocalyx. In eukaryotes, <u>the carbohydrates present on the surface of the cell membrane play a important role in the cell-cell recognition and share information.</u>
