Correct option is A)
There are electrical and concentration gradients in neurons that induce the sodium ions to enter the cell. The resting potential is maintained because the channels for sodium ions are closed. The membrane remains impermeable to sodium ions in the rest state. The membrane is more permeable to potassium passage. The potassium ions leak through the membrane at a greater rate than sodium enters. There is loss of positively charged ions from the inner part of the cell membrane. The inner part of the membrane carries a relatively more negative charge than the outer part of the cell membrane.
Thus, the correct answer is option A.
Because the have hollow bones, feathers, wings, beaks, and they lay eggs
This is what is commonly know as 'peat'. Peat is found in peatlands, bogs, mires and moors, and is an accumulation of partially decayed vegetation or organic matter. The decay is slowed down by a lack of oxygen due to waterlogged conditions. These areas are very important carbon sinks as the CO2 released by the decaying matter is trapped within the peat. It requires thousands of years for peatland to develop. Peatlands are very important as they provide a record of past vegetation and climate within the preserved plant remains.
Answer:
A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.
Explanation:
Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.
Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.
When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.
Answer:
A. peripheral
Explanation:
Peripheral route to persuasion: In psychology, the term "peripheral route to persuasion" is described as one of the two different types of persuasion method and generally occurs when a specific listener or person thinks or decides to get agree with the given message or information dependent on any other cues apart from the strength or quality of any idea or argument related to the given message.
Example: An individual decided to buy something because the outside appearance fantasizes him or her.
In the question above, the given statement signifies the "peripheral route to persuasion".
