Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.
Endocrine signaling is hormone based signaling that travels through the blood stream. Many of the sensors and integrating sensors of the endocrine system are located in the brain. The brain barrier contributes to endocrine signalling, such that the brain barrier does not factor in with endocrine signalling. The answer is A
We know, only 10% of energy transferred from each trophic level. Plant can capture 1% energy from the sun. According 10% law only 10% energy transfer to next level. Thus if plant has 1%- trophic level 2 will have 0.1%; then third trophic level will have 0.01% and we human if we are on fourth level then we will have 0.001%.
Thus correct answer is 0.001%.
The nervous system consists of things like the spinal cord, brain, and all the nerves that connect the sensory organs. Basically, the nervous system helps different parts of the body communicate with each other; thus leading to control of the body.
