Answer:
Dendrites.
Explanation:
Dendrites is the part of neuron which is affected by the substance Y which leads to the decrease of action potential because dendrites is the part that obtain information from other cells and carry that information to the cell body of neuron which transfer this information to the neighboring neurons. If the dendrites is damaged or adversely affected due to chemicals then it is unable to perform its function properly and its action potential will be greatly affected.
Answer;
-Fossil evidence
-Comparative anatomy
-Molecular clocks
Biological evidence of the age of the earth includes fossil evidence, comparative anatomy, and molecular clocks.
Explanation;
-Fossils are critical tools in science because they give us clues to the types of plants and animals that lived on Earth in the past.There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined.
-Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. However, it is also important evidence for evolution. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
-Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
Answer:
Cells. If you are talking about tissue like Kleenex, then easy, soft fabric.

Answer:
We only know it's there because we can see the effect of its gravity. Scientists study dark matter by looking at the effects it has on visible objects. Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. Computers play an important role in the search for dark matter information.
