Answer:
Cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell - The DNA must be copied so there is a full set of DNA to pass on to each daughter cell.
1. <span> A. The algae directly feeds the large-mouth bass and wood duck. Consumers are the same thing as heterotrophs.
2. </span><span>The blue arrow points to an animal which gets all its energy from (i.e., eats) only other animals
3. </span><span>Primary consumers are the organisms which eat producers. So without the primary consumers eating the producers, the number of producers will probably increase.</span>
Answer:
Statements are missing. These are,
1-Consumers may reduce exposure to these by washing and peeling fruits and vegetables.
2-These may be used to increase weight gain and meat production in cattle.
3-These include organophosphates and sex pheromones.
4-Golden rice is yellow because it contains beta-carotene, which the plant can now manufacture because genes for certain enzymes were inserted in the rice genome.
5-Their use may be avoided in favor of integrated pest management (IPM).
6-Scientists inserted the Bt gene into corn to make it resistant to the corn borer.
7-These include recombinant bovine somatotropin (rbS

Answer:
E. that area of the membrane is in the absolutely refractory period.
Explanation:
Refractory period is a period during which neuron cell cannot be stimulated (depolarized). This is why the action potential can only travel in one direction from the neuron body towards axon.
Refractory period occurs because of the inactivation of voltage-gated sodium channels (while action potential is at its peak) which cannot be open for a certain period of time. and membrane cannot be depolarized.
Answer:
Cytokinesis in a plant cell: the cell plate forms down the middle of the cell, creating a new wall that partitions it in two. Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis.
Explanation:
