Well, plants have a vascular system whereas animals have a circulatory system. They both utilize tube structures that transport water and nutrients to the cells and different parts of the organism. Plants have xylem and phloem and animals have veins and arteries. An animal's circulatory system is driven by a pump, via the heart. A plant's vascular system is driven simply by gravity and the many useful properties of water. Plants have water-based solutions within their vascular systems and animals have mainly white and red blood cells within their circulatory systems.

Anything in the environment that can cause a mutation is called as a mutagen.
Environmental mutagens include:
radiations, chemical, infectious agents, extreme heat.
The environment we live in has a real impact on whether we experience genetic mutations. The quality of water we drink and the air we breathe can actually effect the integrity of our DNA. Our bodies are designed to correct any mistakes, but dangers from the environment can increase our chances of ending up with a mutation.
A. movement of air into and out of the lungs
Answer:
They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent.
