Answer:

reduction in potential medicines

reduced food supply

Explanation:

The direct consequences of a decrease in angiosperm's biodiversity is a reduction in potential medicines and food supply.

Angiosperm biodiversity (the flowering plants) act as a source of food to several living organisms, including human. This is evident in the practice of farming by humans. Different categories of consumers in the ecosystem depends largely on flowering plants for their food either directly or indirectly.

They also serve as a source of medicine. For example, chloroquine which use to be the major drug against the treatment of malaria was extracted from a flowering plant known as <em>Chinchona pubescens.</em>

<em>Several species of flowering plants remains in the wild whose usefulness are yet to be researched. They represent a source of future food and medicine for man and animals.</em>

<em>Hence, if the diversity of flowering plants is reduced, it is going to have direct consequence of reduction in potential foods and medicine.</em>

A constant used in an equation for gravity is 0.0000000000667. What is theis represented as a number in proper scientific notati
xxTIMURxx [149]

The correct answer is - C) 667 x 10-13.

The constant that is used in the equation for gravity, or rather gravitational pull, is 0.0000000000667. This same number, in proper scientific notation goes in the shape of 667 x 10-13.

The reason for that is very simple. Any number multiplied with 10-13 will give the exact same number, but as the last part of 13 decimal number. The -13 part dictates the number of decimals. So in the case of 0.0000000000667, the last part 667 is the number that is multiplied, but because the multiplying is in minus, the number goes on the back of the number. Since it has three numbers in it, ten zeros are added in front of it, in order to get the 13 decimals.
