Answer:
All of these environmental disturbances use such energy present within the ecosystem to survive and reproduce. In order to conserve the health of the environment, the best thing that can be done is finding ways to reuse the energy as much as we can such as recycling cardboards or tin cans. Other ways would be to lower use of carbon emitting cars and have more conservation awareness.
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
Explanation:
Answer:
92.
Explanation:
92 chromatids are visible for humans at prophase stage because the replication of 46 chromosomes occur. When the replication of chromosomes occur, each chromosome is converted into two chromatids so when 46 chromosomes replication occur then it changed into 92 chromatids. So we can say that there is 92 chromatids in humans in the prophase stage of mitosis.
I'm pretty sure that each level decreases the amount of energy by a factor of 1/10 so for primary consumers there would be 100 units of energy.
In humans, the "male gamete determines the sex of an offspring because it may contribute either an X or a Y chromosome"
<u>Answer:</u> Option C
<u>Explanation:</u>
Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
