Biomes in the temperature zone have been changed the most by human activity.
We can define biomes as the community or group of animals and plants that are distributed or categorized on the basis of common characteristics of environment they are in, five<span> major types of biomes are aquatic, desert, forest, grassland, and tundra.</span>
They only vary only in their "Lipid Groups"
Hope this helped you!:)
Answer:
According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.
Explanation:
Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the <u>separation of the two daughter cells</u>, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.
In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.
Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.
In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.
The other options are not correct because:
- <u><em>Cell growth</em></u><em> occurs in G1 phase.</em>
- <u><em>Cell preparation</em></u><em> occurs in interphase.</em>
- <u><em>DNA replication</em></u><em> occurs in S phase.</em>
- <u><em>Mitosis</em></u><em> is represented in yellow, and involves 4 phases.</em>
Answer;
A bottleneck effect
Explanation;
When only a few individuals survive unfavorable times, thereby losing the majority of genotypes in the next generation, it is called a bottleneck effect.
It occurs when there is a disaster of some sort that reduces a population to a small handful, which rarely represents the actual genetic makeup of the initial population.
