The three major issues that cut across psychology are stability versus change, rationality versus irrationality and nature-nurture issue.
Stability versus change deals with the issue of whether human beings change as they grow older or they remain essentially the same.
Rational versus irrationality illustrates the disparity between a human's mind ability to perceive and interpret correctly or incorrectly.
Nature - nurture issue centered on the relative contribution of genetic inheritance and environmental factors to human development.
Answer:
Lateral inhibition.
Explanation:
Lateral inhibition may be defined as the ability of an excited neuron to reduce or decrease the activity of ts side by or neighbor's neuron. The sensory [perception is increased during lateral inhibition.
The stronger response is detected at the surface edge rather than on the cell's middle surface. The excited neurons move in the lateral direction and decreases the activity of the middle or neighbor neurons.
Thus, the answer is lateral inhibition.
Answer:
False
Explanation:
Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg. They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.
The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.
Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.
