Answer:
The right answer is c. commensalistic
Explanation:
Commensalism is a type of relationship between two individuals in which one of the individuals becomes benefitted from the other individual and the other individual is not harmed and even not get benefitted from the counterpart.
So, in this case, the bacteria that were living in the spider's gut are benefitted because they got space and environment to live and the spider is not harmed and benefitted because there is no negative effect of presence and absence of bacteria on spider's health which was proved by antibiotic treatment.
Therefore commensalistic relationship might be occurring between spider and the bacteria. So the correct answer is c.
In vertebrates, motor neurons release acetylcholine (ACh), a small molecule neurotransmitter, which diffuses across the synaptic cleft and binds to nicotinic acetylcholine receptors (nAChRs) on the cell membrane of the muscle fiber, also known as the sarcolemma.
Answer:
No
Explanation:
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
Answer:
<u>Folding and faulting-</u> The process in which the layers of the Earth are displaced or moved into a different position due to some forces acted upon them, as there are different reasons due to which the folding and faulting occurs.
- The forces are so power full that they can bring the sediments of ocean to level or elevation above the sea level and can have a destructive effects for the living being. As there are various causes for folding and faulting of these layers,some of these forces are given below;
Explanation:
<u>Geological events causing the folding and faulting-</u>
<u>Tectonic Plates movement-</u> The parts of the Earth layer are always sliding over each other, and when they do they produce huge seismic waves. Which then causes the earthquakes, the folding and faulting of these layers.
<u>Volcanic eruptions : </u>It happens rarely as the number of gases and lava from inside the Earth, down from the crust move upward and erupts, producing dust in the atmosphere.
The other two geological causes are;
- <u>Intrusive igneous activity,</u>
- <u>subduction.</u>
- <u></u>
