The answer is absolute refractory period. The absolute refractory period defines the time of latency that happens after a nerve has been fired. Enduring 1-2 minutes throughout this stage the neuron cannot be roused no matter how tough the stimulus is. It is fundamentally renewing itself in order to be capable to fire again. The NA+ stations in the neuron are neutralized throughout the absolute refractory period and are not capable to react to any stimulus. Succeeding the absolute refractory period is the relative refractory period which is longer in extent and is when the neuron is capable to react to a stimulus but desires a stronger than normal stimulus in order to do so.
The plants will die due to lack of nutrient, causing the smaller animals who feed on plants to starve. The large animals who eat the smaller animals will die off as all there prey (the smaller animals) are dead. Google 'Food Chains' and 'Food Webs' for some in depth explanations.
The answer is C; it isn't performed by cancer cells. This statement is untrue. Cancer cells are indeed capable of reproduction by cell division... in fact, according to most evidence today they appear to be better at it than normal cells.
Hope this helps!

Plant cells have a cell wall, animal cells don't.
Plant cells have a large central vacuole and animal cells have more numerous, smaller vacuoles.
Plant cells have chloroplasts and animal cells do not.
Hope this helps ;)
Answer:
producers that make their own organic matter from inorganic molecules
Explanation:
Phosynthetic organisms are those that capture solar energy and can be used in the production of organic compounds. Through this process they are able to make their own food based on something as simple as sunlight, the organisms that are in this group are: higher plants, algae, some bacteria, which can convert carbon dioxide into organic compounds and of these compounds reduce them into carbohydrates.
The energy necessary for this process to occur, is generated through the light of the same sun, which promotes the activity of these organisms for the preparation of organic compounds and their carbohydrates, which are used by cells as a source of Energy.
It is important to note that most of the foods that are consumed throughout the day and the fossil fuel that is found in nature, are a product of this process called photosynthesis. Photosynthetic organisms are considered to be the largest primary producers within the same trophic chain itself, since among them are those that produce oxygen, which are green plants, algae and some bacteria. But there are also organisms that produce photosynthesis and do not produce oxygen, among these are purple sulfur bacteria and green sulfur bacteria.
