Answer:
D
Explanation:
Sample D will undergo the fastest rate when subjected to chemical weathering.
What is weathering?
- It is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Physical weathering is also known as mechanical weathering. It entails breaking rocks into smaller sized chunks.
- Chemical weathering is the decomposition of rocks by chemical action.
From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.
Reaction rates are affected by:
- Increase in surface area
- Increase in temperature
- Higher concentration
- Increase in pressure
The last cube has the highest surface area and will have the fastest rate of weathering.
1.Proteins. Proteins are found in the blood plasma and all over the body. The functions of protein include: repair and maintenance of body tissue, they are components of some hormones e.g. insulin, they make up enzymes, they make up transport molecules such as hemoglobin.
Lipids. These are used for energy storage and production. They provide energy for muscle and body processes.
Starch. Starch is converted into glucose for energy in the body.
Sugar . Sugar in the form of glucose is used by every cell in the body for energy.
Calcium. A mineral that is used by the body for building and keeping bones and teeth strong.
Chloride (NOT chlorine)ion. Acts as an electrolyte in the body.
Iron. Iron is an essential element of hemoglobin in the red blood cells .

Answer:
released into the environment and unusable. (Entropy)
Explanation:
Ozone is good when it is in the stratosphere but bad when in the troposphere (where the weather system occurs). When in the stratosphere it help absorbs UV light from sunlight before reaching earth surface. This prevents damage to the genetic material of living organisms.
When in the troposphere, it is considered a pollutant and causes irritation of the lungs when inhaled. It also affects vegetation by reducing crop growth and yield.
