Answer:
Here is the full question:
(A) If a closed container contains a mouse as well as enough food, water, and oxygen for the mouse to live for 3 weeks,
How much will the container weigh 1 and 2 weeks later after the mouse has eaten, drunk and exercised (respiration is CO2 emission), and why?
(B) If the mouse was in a wire cage and only the weights of the mouse, food, and water were considered, would you come to the same answer as in (A) and why?
Explanation:
(A) The mouse will weigh the same. This is because solids, liquid, and gases cannot escape the closed container. All of the life processes involving reactions conserve the atoms involved. Some of those atoms will appear in the form of gases, some as solids, and others as liquids but all will be retained in the closed container.
(B) In a wire cage, gases can escape. This means that the weight will not be the same after 1 and 2 weeks. The weight would be less than the original weight of the mouse, it's food, and it's water.
It's erosion. Hope it helps
The best answer is B.
DNA is sometimes referred to as the blue print of the cell's information because it is the store house in which all genetic information necessary for the cell's survival and reproduction is kept.
Without DNA, there cannot be any continuation of life and no new generation of organisms. All living cells and organisms are essentially made up of protein in different forms. Apart from water, proteins are the most abundant molecules in the cell and body where they serves as the major structural component and are essential for growth and maintenance. Information for all these proteins is found in DNA. Without DNA, there can be no protein hence no life.
