C. needed in small amounts.

Minerals are also needed for the body although this should be taken in a very controlled amounts only.
Minerals and vitamins combined form the micro-nutrients of the body.
With micronutrients, only relatively little amount of nutrients is required to improve health. They are usually in milligram and microgram amounts and are enough to sustain to the metabolism and growth supplication. On the other hand, macronutrients are those that need large portions and quantities such as carbohydrates, fats and proteins. We need more of these to be converted to energy for movement and muscle growth.

The pull of the moon on Earth's tidal bulge is causing _____.

Answers

Answer:

High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Explanation:

hope this helps you :)

Answer:

oceans to bulge

Explanation:

The moon appears full when the Earth is between the moon and the sun. In both cases, the gravitational pull of the sun is "added" to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are a little higher and low tides are a little lower than average.

Environmentalists are monitoring an area of tropical forest. They made the following graph to predict the effect of deforestation on this area over the next 20 years.What would a graph of oxygen production look like for this forested area?

A. A line that is leveling out

B. A line that is decreasing

C. A line that is slowly rising

D. A line that is increasing

Answers

The correct answer is option B

By seeing the graph we can easily say that we see a graph that is decreasing. We can predict that in the next 20 years the number of trees will be be reduced in number.

Due to decrease in the number of trees, the oxygen concentration will also decrease. The production of oxygen will decrease for sure as trees are main source of production of oxygen in the rainforest.

B. a line that is decreasing.
if tress are disappearing then oxygen levels would decrease as well since trees give us oxygen and we give them carbon dioxide.
