Answer:
Anaphase
Explanation:
Cohesin is a protein that holds sisters chromatids together. Anaphase begins with the cleavage of that protein, enabling centromeres to split, and the movement of sister chromatides (new daughter chromosomes) toward the poles.
During the anaphase, microtubules that are not attached to chromosomes elongate and push apart. This elongation makes the cell longer and separates the poles.
The correct answer is option A, that is, only DNA comprises nucleotides.
Nucleotides refer to the organic molecules, which function as the monomer units for producing the nucleic acid polymer DNA. Nucleotides are the building elements of nucleic acids. They are comprised of three subunit molecules, that is, a five-carbon sugar, a nitrogenous base, and at least one phosphate group.
<span>factor is a variable
I would say its false, you can test 1 factor at a time</span>
Answer:
Heterotrophs are the organisms which cannot prepare their food on their own like autotrophs instead are dependent on other mode to obtain the organic substances from the environment. This method is common in animal and fungi groups.
Although both fungi and animals are heterotrophs their mode of heterotrophic is different as fungi obtain organic substance b secreting many digestive enzymes which digests the complex biomolecules and the fungi obtain the organic substances whereas the animals swallow or ingest the material and then digests it.
Answer:
Explanation:
Biodiversity varies with a change in altitude or latitude. The diversity increases as we move from high to low altitudes (i.e., from poles to equator). ... There is a decrease in species diversity from lower to higher altitudes on a mountain.
