Answer:
They are neither plants nor animals. They are organisms that are classified under the Kingdom Protista.
Explanation:
Answer:
Plasmolysis occurs when a <u>plant </u>cell is inmersed in a <u>3X salt solution</u>.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
- <em>Plamolysis does not occur in </em><u><em>animal cells</em></u><em>.
</em>
- <u><em>Pure water </em></u><em>does not produce plasmolysis.</em>
Answer:
In the light-dependent reactions, water molecules do not give up electrons easily so the hydrogen ions remain in the thylakoid compartment. The movement of the hydrogen ions back to the stroma is due to the gradient.
The hydrogen ions have energy as they flow down the gradient that takes place due to the chemiosmosis process, oxygen combines and flows or diffuse.
Answer:
The 2 processes that occur in meiosis to create genetic diversity are <em>crossing over and independent assortment.</em> <em>Crossing over is when exchange of DNA segments occurs between homologous chromosomes. Independent assortment is when homologous chromosomes assort independently into gametes. </em>
Explanation:
Meiosis can be described as a process of cell division through which four daughter cells are produced having half the number of chromosomes as the parent cell.
During this process, the phenomenon of crossing over and independent assortment occurs which allows for the genetic diversity which we see in organisms of a species.
During Prophase 1 of meiosis 1, homologous chromosomes exchange segment of DNA between them which leads to genetic diversity.
During Anaphase 1 of meiosis 1, homologous chromosomes move to each side of the cell and the chances of the gamete to receive any of the chromosome is random.
