A lab technician is preparing agar medium. The medium requires 21 grams (g) of
docker41 [41]

Answer:

21.81grams

Explanation:

According to the question, an agar medium requires the following ingredients: 21 grams (g) of

agar, 500 mg of dextrose, 3 dg of sodium, and 1 cg of potassium per 1,000 milliliters (mL) of distilled water.

Hence, the dry ingredient contain 21grams (g) of agar, 500milligrams (mg) of dextrose, 3decigrams (dg) of Sodium, and 1centigrams (cg) of pottasium.

We need to convert all units (not in grams (g)) to grams.

1grams = 1000milligrams

500 milligrams = 500/1000

= 0.500grams.

1grams = 10decigrams

3decigrams = 3/10

= 0.3grams

1grams = 100centigrams

1centigrams = 1/100

= 0.01 grams

Therefore, we have 21g, 0.500g, 0.3g, and 0.01g

The total dry weight of the ingredients will be:

21 + 0.500 + 0.3 + 0.01

= 21.81grams

What is soil erosion? What are the effects of soil erosion? How can we prevent soil erosion? ​
Gnoma [55]

Answer:

you can prevent it by mulching, maintaining a healthy, perennial plant cover, planting a cover crop, or placing stones and woodchips. Soil erosion is displacement of the upper layer of soil. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
