Answer: The role an organism plays in its community is its niche. I Know this is right cause I took this test last year in 11 grade.
Answer:
west to east
Explanation:
The weather system of New York moves in the west to east direction. It is driven by the jet stream which moves from west to east.
The jet stream is nothing but the normal trade winds that blows in and around the equator and move from west to east. While very strong wind forces start blowing from east to west due to the tropical trade winds
<span>mtDNA analysis is the best DNA technology to use. In DNA fingerprinting scientists run a gel electrophoresis of the subject's DNA in order to establish the banding patterns of the DNA fragments. People will always share half of their DNA with a parent. SO half of an individual's banding pattern will match half of their parent's DNA banding pattern. If someone is missing is found then scientists can compare the DNA fingerprint or banding patterns to see what the likelihood is of them being related.</span>
Answer: 170 calories.
Explanation:
The Viceroy caterpillars feeds on the green plants and trees for its survival. The total energy that is incorporated in the body of the caterpillar is used in cellular respiration, faces and rest amount of the energy left is used as biomass by the caterpillar each day.
The total energy is 1000 calories, 50% of this energy is 500 calories which is released out of the body through faces. Rest 33% of total energy( 330 calories) is used in cellular respiration.
The rest amount of energy that is available is 170 calories.
Answer
→ to lose sensation,
→ motor control
Explanation:
Anatomically the spinal cord is made up of two roots, the Dorsal roots or the posterior roots where motor or efferent neuron leaves the spinal cord to innervate the skeletal muscles, trunks and the Ventral root or anterior roots where the afferent or sensory neuron convey input signals to the spinal cord from the the receptors.
Polio virus usually destroyed the nucleus of motor neurons, in the ventral roots of the spinal cord. its inflamed these cells, leading to death, The death leads to consequent degeneration at the site of inflammation, and progressive spread of this to other segments of the nerve fibre. This is called Wallerian Degeneration. Thus mechanisms of generation and transmission of action potential in these motor neuron is inhibited.
Consequently, motor output signals by the efferent neuron leaving through the dorsal roots is disrupted, and blocked . Thus effectors-muscles of limbs,trunks, are no longer innervated and stimulated, by efferent responses from the spinal cord and the brain, thus leading to loss of sensation and motor control.
With muscles redundancy, from lack of stimulation, muscles cells begin to waste away(muscle atrophy), and not able to control by the victim.This is paralysis.
