Answer:
Absence of a nucleus
Explanation:
In eukaryotic cells, DNA is typically harvested and saved in the nucleus, though prokaryotic cells lack a nucleus, so the DNA merely floats in the cytoplasm instead.
Answer:
Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons. </u>
Explanation:
Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.
The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.
Answer:
The mindset is the most important trait to pass on to your children.
Due to the <u>mutation </u>accumulation, the <u>binary fission</u> in bacterial population will decrease due to in ability to divide (Due to inactive replicating enzymes). In the similar way, the <u>generation time</u> will also decrease.
Binary Fission- Binary fission, also known as asexual body division into two new bodies, When an organism divides into two halves (cytokinesis) by binary fission, it doubles its genetic material, or DNA, with each new creature acquiring one copy of the latter.
Generation Time- The amount of time it takes for a colony of bacteria to double in size is known as the generation time. The generation period for various bacteria ranges from a few minutes to many hours. Bacteria multiply by geometric progression because of binary fission.
