Answer:
The correct answer is - 2.107 x 10^24 mango seeds.
Explanation:
Given:-
number of moles of mango seeds = 3.50 mol
Solution:-
1 mol of mango seeds = 6.02 x 10^23 mango seeds
6.02 x 10^23 is Avagadro numbers
1 mole is the number of particles contained in a substance
. The number of moles can also be calculated by dividing the mass by the molar mass of the element or molecule of the substance with the Avogadro's number.
Therefore,
3.50 mol of mango seeds = 3.50 x 6.02 x 10^23 mango seeds
3.50 mol of mango seeds = 21.07 x 10^23 mango seeds
3.50 mol of mango seeds = 2.107 x 10^24 mango seeds
A and C since they have a charge
500 because of the 10% rule when moving up in food chains, for example; patch of grass-200J rabbit eats some of it but doesn’t eat all - 150J the rabbit runs around for a bit and loses energy, the fox doesn’t eat all of the rabbit - 50J ( just a rough example may not be completely right but the concept of the rule is there and the energy).
<span>When
a plant opens and closes its stomata, it is maintaining its respiration and
helps the Earth’s breathable atmosphere. Stomata (stoma) by dictionary
definition is a small opening on a plants’ epidermis (mostly on leaves) with
which gas exchange happens, carbon dioxide in, oxygen out.</span>
Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
