Ou need to measure three things: 1. a quantity of water 2. the length of a leaf 3. the mass of a small stone which unit of metric measurement will you use for each one?

1.

2. m

3. kg

Explanation:

As we know that there are seven fundamental SI units which are used to fine derived units. These are as follows:

1). Mass - Kilogram

2). Length - meter

3). Time - Seconds

4). Electric Current - Ampere

5). Amount of substance - Moles

6). Intensity of light - Candela

7). Temperature - Kelvin

The metric system uses three main units for measuring:

length in meters (m)

mass in kilograms (kg)

volume in cubic meters

Thus a quantity of water is measured in units of volume , the length of a leaf is measured in units of length meter (m) and the mass of a small stone in kilogram (kg).

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
