Answer:
this mean the certain number of organisms an ecosystem can hold without being overrun and potentially destroyed.
Four times as much genetic material is present in a cell during prophase I compared to a cell that has competed meiosis II. Prophase I is a phase in the first stage of meiosis (meiosis I). During this phase, chromosomes become visible. cross-over occurs, the nucleolus disappears, the meiotic spindle forms and the nuclear envelope disappears. The genetic materials in prophase I divides into two at the end of meiosis I forming tow daughter cells, which then divides again into two at the end of meiosis II forming four daughter cells.
Answer:
Answer is C
Explanation:
Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. These molecules pass across membranes via the action of specific transmembrane proteins, which act as transporters.
