Answer: First, Third, Fourth and Fifth options are correct.
Explanation:
Synapse is the gap between neurons.
It carries information through electrical impulse or chemical impulses to the cell body.
It is the part of nervous system.
It allows information to travel either in electrical form or in chemical form.
It ensures that the information travels in only one direction.
It is not the part of neurons while it is the connection between separate neurons.
Hence, First, Third, Fourth and Fifth options are correct.
1. The problem: THE DECLINING OF CORAL COVER OF REEFS.

Explanation:
1.) In a chemical change, the molecules in the reactants interact to form new substances. In a physical change, like a state change or dissolving, no new substance is formed. Explain that another way to say that no atoms are created or destroyed in a chemical reaction is to say, “Mass is conserved.”
2.) Carbon Dioxide and Water Out: During combustion, the atoms in ethanol and oxygen are rearranged into carbon dioxide and water. The carbon dioxide and water leave the top of the flame.
Some key reasons for partially developed offspring:
• Genetic issues, parents sexual organs incorrectly formed, in turn malforming the offspring
• Pollution, parents consuming something they shouldn't have while the offspring was developing
• Breeding between relations; accidently mating with a brother or sister, in turn causing defects as many of the genes are the same
