Answer:
Option D.
Explanation:
The above answer given is incorrect. Nucleotides consist of a phosphate group attached to a pentose sugar, with 5 carbons, (deoxyribose sugar in the case of DNA) and the pentose sugar is also attached to a nitrogenous base. DNA is incorrect as nucleotides are the building block of DNA hence DNA is NOT a component of nucleotides.
Answer:
The color of the surfaces because an object with a black surface will absorb and reradiate energy faster and at a higher concentration than the same object with a lighter colored surface.
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:
the shape
Explanation:
If it’s round it would be animal and if it’s square-like it would be plant cell. Hope this helps!
