Which description best fits the activity of a cell during interphase?
question 11 options:

the cell carries on metabolism.

the cell differentiates to have a new function.

the cell splits in two.

the cell splits in two but with half the normal number of chromosomes.

The correct option is A) The cell carries on metabolism.

Explanation:

Interphase can be described as the phase of cell cycle in which the cell spends most of its time. In this phase, the cell carries out its normal metabolic functions and prepares it self for division. The phase of interphase is divided into three parts which are the Gap 1, Synthesis, and Gap 2. Hence, the correct option is A.

Other options, like option C, is not correct because the cell splits into two during cytokinesis.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
