1. Which of the following statements best describe the difference between angiosperms and gymnosperms?
GREYUIT [131]
1) C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination. This is the best answer, because the others had the two types reversed. Gymnos have "naked" seeded cones, whereas Angios have seeds protected by fruit. Therefore the Angios relies on animals to eat the fruit and to pollinate, whereas Gymnos relied on wind to pollinate the ground. Gymnos came first on Earth and Angios developed later.

2) C. Cuticle. This is a waxy coating helping to keep water in. The main water losses are via stomata.

3) C. Stomata

4) B. Nonvascular

5) B. Gravity

These answers were explained in the questions that I just answered before. So refer to those for explanations.

Which statements accurately describe soil? Check all that apply.
ahrayia [7]

Answer:

Soil condition directly affects crop growth.

Explanation:

Soil condition affects the crop growth directly. If a soil is in fertile condition then the growth of crop which is growing in such soil will be good but if the soil is infertile then the crop will not grow to its fullest. A fertile soil is the one which has optimum condition for growth of a crop like suitable pH, moisture retention capacity, good amount of nutrients & minerals like nitrogen, phosphorus, sodium, potassium, magnesium etc. If a soil is rich in all these constituents then the crop which is growing in this soil will be healthy. But, if a soil is infertile then the crop which is growing on that soil will be under stress and will not be able to grow completely.
