Answer:
A neuron's nucleus is located in its CELL BODY
A nerve impulse moves toward a neuron's cell body along AXON
Explanation:
A neuron consists of three major parts: cell body, dendrite and the axon.
1) The cell body consists of the nucleus and cytoplasm
2) Dendrites are short cytoplasmic filaments which conduct impulses towards the cell body
3) Axon is made up of a single, long fibre which transmits impulses away from the cell body
Answer:
The correct answer is option e, that is, unpaired loop.
Explanation:
For base pairing to take place, the duplicated or the deleted region will not possess any kind of complementary region. Thus, it produces an unpaired loop. The formation of the inversion loop takes place at the time of paracentric and pericentric inversion. A high-level packaging composition produced by chromatin is known as a solenoid. A bead on string structure produced by enveloping DNA around the core of histone proteins is termed a nucleosome.
Answer:
Explanation: Natural selection is a cause of evolution. So over time, organisms can start to evolve due to artificial selection. Natural selection, sometimes referred to as "survival of the fittest," is a mechanism for the evolution of a population to become better adapted for survival in a specific environment. This means that organisms with traits that are best suited for the environment will pass these traits to their offspring.
