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.

What structures work in antagonistic pairs to move bones?

Olegator [25]

Answer

Option C - Skeletal Muscles

Explanation

Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.

Explain why competition between individual of the same species is more often more intense than competition between memories of d

puteri [66]

One big reason for this is because individuals of the same species often have to fight over shared resources (this means shared food and shared environment).

Because they fight over a limited amount of space and food, competition between individuals within one species can be present and very tough.

On the other hand, having members of different species also possibly means different territories and different food sources. A lion has no quarrel with dolphins, while it can have a lot of fights with lions from different prides (large group of lions).
