Explanation:
wolfs play a key role in keeping ecosystem healthy the Caracesess of their prey also help redistribute nutrients and provide food for other wildlife species like, grizzly bears and scavengers..
The substance that is predominately absorbed in rain forests would be carbon dioxide, I believe. As many tropical trees are present and will uptake CO2 to synthesize glucose or sugar as a product of photosynthesis.
The sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
<h3>What is diffusion?</h3>
Diffusion is the process by which substances move from region of high concentration to regions of low concentration.
Based on the chart, sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
This is because the ions are at higher concentration in the pond water.
During the process, the ions move through ion channels in and out of the plant cell from the pond water.

Answer:
Crossing over and random alignment are the events of meiosis-I that add new gene combinations to the gametes. Random fusion of male and female gametes is called random fertilization.
Explanation:
During the pachytene stage of meiosis-I, part of the chromatids of each of the homologous chromosomes of a bivalent is broken apart and exchanged. This exchange of the genetic material between the members of a bivalent is called crossing over. The recombinant chromatids formed by crossing over have new allele combinations that were otherwise not present in the parental chromatids.
During metaphase I, the homologous pairs are aligned at the cell's equator in a random manner. This means that either the paternal or maternal chromosome of a pair may face one or the other pole of the cell. The arrangement of chromosomes during metaphase-I determines whether the paternal or maternal chromosome of each pair would be distributed to one or the other pole of the cell. This random segregation creates new gene combinations in gametes.
All the gametes have equal chances of getting fused with a gamete from the opposite gender. This is called random fertilization and further adds variations.
Answer:
The correct answer is A water will diffuse from inside to outside of the cell
Explanation:
According to the given question a cell containing 5% salt solution is placed into a glass of water with 20% salt solution.That means the salt solution present in the glass is hypertonic to the salt solution present inside the cell.
As the cell is kept or placed in a hypertonic solution water will diffuse from inside to the outside of the cell.
