Answer:

A. When the animal dies, it decays and the nutrients from its body go back into the earth where they are absorbed by plants.

Explanation:

The plants as the animals need nutrients to be able to survive and they get them from the solar energy but also from the soil. The plants absorb nutrients that they found in the soil through their roots and they can come from rocky material in the surface and from the decomposition of dead plants and animals. So, according to this, the answer is that plants get nutrients from animals because when the animal dies, it decays and the nutrients from its body go back into the earth where they are absorbed by plants.

How does the concept of polarity relate to bond formation and molecular shape?
Ket [755]

Answer: heyyyooo

The bond polarity for each bond in a BH3 molecule is polar, due to the difference in electronegativities of the B and H atom. The molecular shape is trigonal planar, and the molecule is non-polar - because due to the symmetry of the molecule, the polarities cancel out.

Convert 7.50 mol of Li₂O to grams
Natali5045456 [20]

Answer:

223.5 g

Explanation:

The formula between the number of moles, mass and Mr can be used to convert moles to grams.

<em>Number of moles = mass ÷ Mr</em>

So, mass = number of moles × Mr

  Mr of Li₂O = (6.9 × 2) + 16 = 29.8

∴ Mass = 7.5 × 29.8 = <u>223.5 g</u>

During which two minute time period is the temperature of the water changing fastest? Select one: a. 0-2 minutes b. 2-4 minutes
olga_2 [115]

Answer:

b. 2-4

Explanation:

Look at the slope of the line, between 0-2 and 4-6 the slope is only 10, but between 2-4 the slope is 20, so that's when the temperature is changing the fastest. In the same time it took for the water to increase by 20 degrees between 0-2 and 4-6, the temperature of the water increased by 40 degrees between 2-4 so that's when the change is the fastest.
