Answer:C

Explanation:

Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.

It has a value of -50 and -75mV.

Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)

In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .

These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.

The movements of these ions across the membranes generated electrical potential difference for action potential.

Triss [41]

The formation of macromolecules from triose phosphate is likely anabolic and would be coupled to ATP -> ADP.

Anabolic is a group of metabolic pathways that builds compounds out of smaller building blocks. These reactions, which are often referred to as endergonic processes, demand energy. Catabolism is the breakdown component of metabolism, whereas anabolism is the building component. Typically, anabolism and biosynthesis go hand in hand. Anabolism can be seen in the growth of muscle mass and the mineralization and development of bones. Proteins are broken down into amino acids during catabolic events, as are glycogen and triglycerides into glucose and fatty acids, respectively. Fundamentally, catabolism entails disassembling complex molecules to produce energy that may be utilised by the organism. By building larger, more complex molecules from smaller, simpler ones, anabolism is the exact reverse of catabolism. The body typically stores them for later use.

Protein supplies approximately __________ percent of a human's typical energy needs.

andreyandreev [35.5K]

A human needs approximately 2-5 percent of protein for the typical energy needed daily. Protein is one of the most important building blocks in the body. It helps the bones, muscles, skin, blood, and cartilage. A humans nails and hair are made of protein. The protein your body uses also repairs tissues and build new ones.

Stells [14]

A person does have basic human rights and one is the freedom of expression. Though this is the case, we should understand that our right to freely express ourselves (from political to religious views), it does not necessarily give us the right to impede another person’s. A play with words can easily hurt or even harass other people, and in return may be a form of human right violation.

Schach [20]

Answer:

Zooplankton

Explanation:

The correct answer here would be the zooplankton. (see the attached image)

<em>Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem. </em>

<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
