Answer:
In Darwinian terms, the fittest individuals of a species are those that attracts the most mates and leave the greatest number of reproductive descendants.
Explanation:
Darwin's evolutionary theory have mentioned "Survival of the fittest'' that described the mechanism of natural selection.
The survival of fittest means the maximum rate of reproductive success.
Those individuals that leaves maximum copies of it's offspring which are actively successful in reproduction and transmit it's features to the next generation are fittest individuals.
Charles Darwin mentioned this on his book'' Origin of species'' in 1868
Survival of fittest is the alternative form of natural selection.
Survival of fittest ensures the chance to improve phenotypic characters.
D, Energy decreases from bottom to top because some is used at each level for life processes.
Answer:
The sodium channel have refractory period.
Explanation:
Action potential are generated at axon hillock of neuron and travel across the neuron in response to stimuli. For the the generation of action potential the steps are stimulus, depolarization, repolarization, hyperpolarization and resting state.
So the first step for action potential after stimulus is depolarization. Depolarization requires the opening of sodium channels to make the inside of neuronal membrane positive. These sodium channels have refractory period. They cannot open immediately after activation. So the sodium channels of one direction in neuron (upstream) become refractory and it is convenent to open the sodium channels of other direction (downstream) of neuron. That why action potential is transmitted in one direction.
It is like the gunpowder placed at a line the fire cannot go back in burnt gun powder direction.
Endomysium (connective tissue that surrounds each muscle fiber (cell))
Answer:
D. RNA sequence is incorrect.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.
This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).
