In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
Answer:
Which of the following is an advantage of an in vitro experiment?
Variables and environmental conditions are controlled.
Explanation:
An advantage of in-vitro experiment is that the variables and environmental conditions are controlled because in-vitro experiment is performed outside a living organism with the environment in control
Answer:
Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.
Explanation:
The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.
Both of these have opposite actions on the functions that they maintain.
The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.
The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.
Thus, the comparison of these nervous systems is mention above.

Answer:
A. Nuclear reactors increase thermal pollution
Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
