I believe they cannot start with big trees and bushes because the there is not enough nutrients in the soil, so instead pioneer species pave the way for primary succession.
Answer:
the fact that rod functioning predominates during dark adaptation, therefore poor acuity
Explanation:
- Rods and cones are the photoreceptor cells present in the eye that perform the function of converting the light received into signals that stimulate the biological processes.
- Out of the rods and cones, the rods are more sensitive and they are so sensitive that they can be activated even under low light conditions.
- However the cones can be stimulated only under bright light conditions, but the visual acuity is higher for the cones as compared to the rods.
- <em>Therefore under conditions of dim light, the rods are activated and hence it results in a poor visual acuity and a person experiences difficulty in reading. </em>
According to the CDC, tooth decay
affects more than one-fourth of U.S. children aged 2 to 5.Tooth decay is the
damage of the structure of the tooth which is caused by acids that are produced
when sugar is being broken down by plaque bacteria in the mouth. Tooth decay is the primary cause of tooth loss in children in the United
States.
Answer:A
Explanation:
The mass of an electron is equal to the mass of a neutron
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
