I believe the answer is:
The "spontaneous firing rate" of a neuron refers to <span>its rate of producing action potentials even when it is not stimulated.</span>
Explanation:
Water enters the atmosphere through three processes: evaporation, transpiration, and sublimation.
Your undertone is neutral since it is a mixed of cool and warm undertones. Cool undertone appears to be blue or purple in light while warm undertones appear green or olive in natural light. Knowing the right undertone will help you to know what the right foundation you'll choose.
For women, the possibility of pregnancy begins in the ovaries. A woman is born with 1 to 2 million eggs, more than a lifetime's supply. The eggs begin dying off almost immediately and she never produces more. The average egg lives only about 24 hours, so it has to be fertilized soon for pregnancy to happen. If it doesn't get fertilized on time, it either dissolves or is absorbed by the body. When an egg is fertilized, its own genetic material and the genetic material of the sperm that got to the egg first combine to create a new cell that starts dividing rapidly. A woman isn't actually pregnant until that new bundle of cells (called the embryo) travels down the fallopian tube and attaches to the wall of the woman's uterus. The average pregnancy lasts for 38 weeks from the date you conceive (called conception). However, doctors usually date your pregnancy from the first day of the woman's last menstrual period. Using this method, a pregnancy is said to last 40 weeks, or 280 days.
Answer:
C. Disruptive Selection
Explanation:
Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.
The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.
The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.
Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
