Myelin sheath. It is a layer of lipids produced by Schwaan cells around the axon of neurons. The sheath increased the rate of electric impulse transmission through the axon, several folds. This process is called saltatory conduction where impulse ostensibly hops from a node to another.
Answer:
The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.
Answer:
Transformation
the ability of a substance to change the genetic characteristics of an organism
The "control" step of intergrated pest management involves the use of pesticides to control pests and their damage.
<u>Explanation:</u>
IPM have four steps, which is a sequence of pest control method. When the thresholds for surveillance, detection and intervention suggest the need for pest control and prevention measures are no longer efficient or usable, then IPM (intergrated pest management) initiatives determine the appropriate management system for both efficacy and risk.
Efficient, less dangerous pest controls, involving highly concentrated chemicals like pheromones to hinder pest mating or mechanical control like trapping or weeding, are selected first. If more analysis, detection and intervention thresholds suggest that less dangerous controls do not operate, then alternative pest control approaches, like targeted pesticide spraying, will be implemented.
The left atria is responsible associated with the pumping of oxygenated blood from the pulmonary vein, whilst the right pumps deoxygenated blood from the vena cava.
