Answer:

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.

Explanation:

The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.

Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.

During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.

balandron [24]

Divergent boundary.

This is the boundary between two tectonic plates move away from each other in opposite directions.

Explanation:

One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.

When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.

The ​ DNA molecule is very similar among all living things. The pairings are always the same and there are only six components t
Gala2k [10]

Answer:

The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.

Explanation:

DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.

The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.

What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.

The other options are not correct because:

  • <em>The sugar component of DNA is always the same, not different. </em>
  • <em>Organisms always use DNA in the same way. </em>
  • <em>The DNA molecule is always the same.</em>

Natali5045456 [20]

Answer:

(3) muscles in the injured arm will get smaller because thy are not being used.

Explanation:

Muscle atrophy is the process caused due to the lack of physical activity. The lack of mobility, as a results of disease or injury, can results in muscle wasting. Without regular movement an injured arm or leg will appear smaller but not shorter than an uninjured one.
