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

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

How is a dicotyledonous leaf adapted for maximum sunlight and carbon dioxide for photosynthesis? 20 Points if ya help meh out lo
jok3333 [9.3K]

Answer:

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
