Answer:
B
Explanation:
Cytokinesis, which is the division of a cell's cytoplasmic content, is the final step of cell division. After which the genetic material of a cell duplicates, they move towards opposite directions in the cell. The cytoplasm of the original cell halves itself equally for the two resulting cells. Though both animal cells and plant cells go through cytokinesis, they undergo it differently due to the presence of cell wall in addition to the cell membrane in plant cells.
In plant cells, cytokinesis mainly involves the formation of a CELL PLATE at the equator of the parent cell that will soon divide into two. The cell plate, which is the future doubled cell wall that will become separated into two cells, divides the cytoplasm.
In animal cells, cytokinesis occurs in a more complex manner. A fissure called CLEAVAGE FURROW develops by the formation and contraction of the CONTRACTILE RING, which is present beneath the parental's cell membrane and made up of actin filaments. The created furrow grows deeper (as the actin ring contracts) between the two resulting cells until they meet the membrane and pinch off (inwardly), separating from one another. Hence, resulting in two separate daughter cells.
Answer:
Excessive synthetic fertilizer that washes into ponds may be the reason for which algae become so abundant.
Explanation:
Algal blooms that feed on fertilizers can deplete oxygen in water, thereby producing inhospitable ponds. In this regard, it has been shown that the runoff of fertilizers from farms (which are rich in nitrogenous matter) may cause algae to become abundant in coastal environments, depleting oxygen in the water and killing the living organisms that inhabit these areas.
