The correct answer is option A , C and D

The earths material is recycled and this can be visualized from the different chain cycles such as nitrogen cycle, carbon cycle , sulphur cycle, water cycle etc. These basic components which constitute all the matter existing on earth are continuously recycled and reused. Likewise the energy obtained from sun is neither created nor destroyed; it is only converted from one form of energy to the other form. Such as heat energy obtained from sun is converted into kinetic energy when it converts water into water vapor.

With regard to the process of neural transmission, a refractory period refers to a time interval in which:

frutty [35]

<h3><u>Answer;</u></h3>

d. a neuron recharges before it can fire again.

<h3><u>Explanation;</u></h3>

<em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
<em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.

Cells are categorized as either prokaryotic or eukaryotic. classify the characteristics below as being unique to prokaryotic cel

dezoksy [38]

Prokaryotic cells: lack membrane-bound organelles, relatively small - typically less than 10 μm in size.

Both cell types: use ribosomes to synthesize proteins, contain DNA.

Eukaryotic cells: complete copy of DNA stored in multiple chromosomes.

In particular, prokaryotic cells have no nucleus and no membrane-bound organelles, therefore their ribosomes float freely intracellularly. On the other hand, eukaryotic cells have nucleus and membrane-bound organelles. Also, their DNA is bound to proteins and stored in the form of chromosomes in the nucleus.
