Unicellular organisms excrete waste by a contractile vacuole. A vacuole is membrane-enveloped organelle in a cell that is found in lots of microorganism. It expands, filling with water then contracts, removing all of its contents to the exterior of the cell.
The rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.
<h3>What do you mean by Evolution?</h3>
Evolution may be defined as the process of growth and development or the theory that organisms have evolved and developed from past organisms.
Biome changes occur due to the fact of evolution. Both evolution and biome changes synergistically move forward to support organisms' life in a much better way.
Therefore, the rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

#SPJ1
The answer is A) That the seed eating species would disappear, because the seeds would disappear followed by the finches that ate those seeds and the other finches that eat other food like insects would thrive.
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>
