Humans would not be able to breathe and sound would not be able to travel also there would not be any life
~in which there would be no plants because humans breathe out carbon dioxide and if there are no humans then plants won’t be able to consume carbon dioxide
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.
The statement is - True.
The Tasmanian tiger went extinct because of the extensive hunting by the new settlers. People were killing the Tasmanian tiger because they thought that it is the animal responsible for the killing of the livestock, but at the end it turned out that they made a huge mistake and that actually the feral dogs and the dingo were the ones responsible for that. The last Tasmanian tiger was a female and died in captivity under very bad conditions.
Even though people use the term Tasmanian tiger (because of the stripes) and Tasmanian wolf (because of the dog-like face), it is an animal that is not related with neither the cats nor the dogs, but instead it is a marsupial, the biggest marsupial carnivore in the recent history, and its real name is Thylacine.
According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.
<h3>What is Punnett Square?</h3>
Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.
The complete question is described in the image given below:
When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.
In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).
Therefore, the correct for this question is B.

Answer:
C. The cells that make them up each contain genetic information.
Explanation:
A and B are not the answer because prokaryotes are unicellular organisms while eukaryotes are multicellular organisms. D is not the answer because prokaryotes do not have a nucleus, leaving the DNA floating in the cytoplasm.
