The correct answer is B: The cells will have 2n chromosomes and be diploid.
Diploid cell have two of each chromosome, one from each parent. When diploid cell undergoes mitosis, the result is two identical diploid cells (when haploid cell undergoes mitosis the result is haploid cell). This means that during the mitosis, cells reproduce genetically identical copies of themselves.
The answer would be C.
Nonpolar molecules cannot form hydrogen bonds that polar molecules can. Interactions between nonpolar molecules are very weak thus D is wrong. And water can climb up inside plants and has adhesion and cohesion because of it’s strong hydrogen bonds.
<span>Excess carbohydrates in Animals are stored as fats. It mainly gets stored in the skeletal muscles and liver in the form of glycogen. Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy. </span>
Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
