They transfer energy parallel to the wave
A
Most scientists rejected Wegener's theory because he could not explain the force that pushes or pulls the continents.
The provided question is incomplete as the image is not given, however the correct image is attached.
Answer:
The correct answer is - embryo.
Explanation:
Angiosperms form embryos by the fertilization of pollen and ovule which are haploid structure and form diploid in the structure. It is also known as the seed embryo.
It is the structure that contain early life form of the plant which is root, leaves and stem.In this image pointer is showing the diploid or 2n structure which is embryo of the plant.
Thus, the correct answer is - embryo.
Answer:
D. How deep the lake is
Explanation:
The benthic zone is the zone that is at the bottom of the lakes. This means that the characteristics of this zone and weather photosynthesis will be a possibility depend on the depth of the lake. If the lake is deep, then the photosynthesis will not be possible in this zone as the sunlight will not be able to reach it, thus this zone will be very poor in organisms. On the other hand, if the lake is shallow and the water is clear, then the sunlight will be able to reach the benthic zone, thus providing the conditions for the process of photosynthesis, and it will be very rich in organisms.
Answer:
The answer is Norepinephrine.
Explanation:
Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.
Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.
I hope this answer helps.
