Explanation:
Many violent volcanoes spew a lot of pyroclasts and gases such as carbon dioxide and sulfur dioxide high into the atmosphere. The fine pyroclast would linger in the atmosphere for months and even years blocking out the sun. This would cause vegetation to die out and decrease. Photosynthetic organisms re usual producers and the entry point of energy from the sun into ecosystems. Their death would mean the collapse of ecosystems.
Settling pyroclast would also blanket vegetation in thick layers hence also denying them access to sunlight. There would be a definite drastic decline in population and communities and ecosystems, and even extinction akin to the extinction even to the dinosaurs during the meteorite strike.

Answer:
Most cells of adult mammals spend about 24 hours in interphase; this accounts for about 90%-96% of the total time involved in cell division. Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase
Answer:
Sickle cell anaemia is a generic disorder which affects the red blood cells. The red blood cells assumes a sickle shape and contains lesser amount of the protein hemoglobin. Hemoglobin helps in the necessary transport of oxygen to other parts of the body.
The sickle cell allele is known to be advantageous to mainly people who stay in developing/underdeveloped counties who malaria endemic . People with the sickle cell allele have a higher chance of survival against malaria than people without this allele.
In modern countries malaria isn’t prevalent there due to the lack of vectors, poverty and environmental conditions which tends to support the survival of the mosquito. This means the sickle cell allele isn’t advantageous in this region.
Explanation:
I think it's answer is sea star
The specialized parts are called lipid rafts, which is comprise
of hospholipase that are way too similar to each other and does not have
proteins which are linked with them. These are accountable for cell to cell
communication, gesturing, and acknowledgment.
