Answer:
Option B, Barr graph
Explanation:
A bar graph is used for comparing several items all together based on any certain parameter.
Here, the lead content is the comparison parameter while the six sample of contaminated water wells acts as different items being compared.
A line graph is good to show a continous varying data set, while a circle graph is good to represent the component constitution of any major substance and a data table is best to represent a data set with multiple attributes.
Hence, option B is correct
Answer:
Explanation:
Yes, for a couple of reasons.
1. Carbon connects easily with other carbons.
2. Carbon forms chemical that can change and connect with other carbons even in biology or especially in Biology. If you take a brown seen and plant it where it can get water and soil nutrients, to will come up as a green plant. Think about the chemistry that goes into that. Not only that, but there are mechanisms that tell the upper part of the plant that the roots can't supply any more growth. Isn't that something? All made from Carbon.
3. The human body is a mass of Carbon based chemicals and all cells there can have different functions. Amazing isn't it? I'm a fan of the diversity of our planet and its growth.
Mathematically the it would be D
but scientifically since eventually food and resources will start becoming scarce it would be A then as the ecosystem recovers it goes back to D <span />
Answer: A
Explanation:
Exponential growth simply means a rapid increase in size and a constant growing rate
