2 answers:

7 0

The answer is to control the crossing of the traits.

The idea of preventing plants from self-pollinating is to control the crossing of the traits. If plants were self-pollinating, he could not know if the traits are inherited from the same plant or from the other. By preventing this, he could cross parents with known phenotype and that way learn about crossing process and inheriting process.

Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin

marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

a teen, her required adequate intake (RAI)= 1300 mg/ day
an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium= $\frac{270}{1300} * 100=$ = 20.8 ≈ 21%

=0.21

21% of her daily calcium needs is in a cup of cooked collard greens.

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
