Name one channel (gated or nongated) through which chloride ions could pass into the cell.
SpyIntel [72]

<u>Passive chloride</u> and <u>GABA</u> are the channels through which chloride ions could pass into the cell.

<h3>What are chloride channels?</h3>

Ion channels are used by cells to regulate many cellular functions, from action potential conduction to water balance, which is sometimes achieved by using a single ion in the setting of different channels types.

Although ion channels are described as transmembrane proteins that have a “pore” which allows for the diffusion of specific ions across a concentration gradient, other channels involved in ion transport include antiporters (exchange), symporters (cotransport in the same direction) and pumps (use energy from hydrolysis of ATP).

Chloride channels are a remarkable example of this since they are involved in the control of transepithelial transport, membrane excitability, and the regulation of cell volume and intracellular and intraorganelle pH.

All of this is achievable by the use of the many different types of chloride channels, of which there are three major families: the voltage-gated chloride channels, the cystic fibrosis transmembrane conductance regulator (CFTR) and related channels, and the ligand-gated channels activated by gamma-aminobutyric acid (GABA) and glycine.

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
stiv31 [10]

Answer:

On the exterior of the cell.

Explanation:

The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.  

In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.  

After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.

How dose natural selection affect population by?
QveST [7]

Answer:

individuals that develop beneficial traits have a better chance of survival, and are then able to pass on their genes. Eventually, if enough of those genes are passed on, that gene will become more prominent within the population.
