Answer:
The correct answer is - a, and b.
Explanation:
Plasticity is the ability of the change in the brain during course of life span. It is a remarkable ability to recovery after the surgery or removal of the part of the brain or injury to the brain.
The neurogenesis is the ability to the regeneration of the nervous system cell, it can occur in the adulthood as well however it takes approximately six week time.
Thus, the correct answer is - a, and b.
Answer: did you figure it out?
Explanation:
Answer:
Reinforcement
Explanation:
Reinforcement can be referred to as anything that can be used to increase, enhance or strengthen a desirable behavior in a person or an organism. Reinforcement is of two types, they include positive reinforcement and negative reinforcement. Positive reinforcement has to do with adding a reward in order to enhance a desirable behavior, while negative reinforcement has to do with removing an undesirable thing in order to strengthen a desirable behavior.
From the question asked, because the presence of insects after moving the decaying logs increased the frequency at which the bears moved the decaying logs, the finding of the insects is, therefore, a reinforcement. The finding of the enhanced or strengthened the desirable behavior.
Answer:
The correct answers to the question are:
- The concentration of solute bathing the inner side of the plant cell membrane should be high.
- The concentration of solute bathing the outer side of the plant cell membrane should be low.
Explanation:
- Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
- This happens when the cell takes up water from its environment and stores it in the vacuoles.
- Water enters to the inside of the cell by the process of Osmosis.
- Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
- In any region, the concentration of solute and and concentration of solvent bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
- In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
- Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.
