The energy from sunlight comes in the form of photons, and this energy is used in the light dependent reactions of photosynthesis. The first function carried out by the photons in energizing electrons in the chlorophyll. The energized electron travels through the electron transport chain and subsequent steps are carried out to utilize this energy to form ATP.
Answer:
39.82 %
Explanation:
Proteins and carbohydrates provide 4 calories per gram. On the other hand, fats provide 9 calories.
We can first calculate the calories of protein + carbohydrates:
(30g + 4g) x 4 = 136 calories
And we must calculate the calories provided by fat:
10g x 9 = 90 calories
Now to get the percentage we must see how many calories the dessert has in total:
136 + 90 = 226 cal
This represents 100% of calories. And now we need to find out how much 90 calories are from the total.
226 cal -----> 100%
90 cal ------> X
(90 x 100) / 226 = 39.82 %
<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>
A patient with sickle cell crisis will most likely complain of severe pain.
A patient with sickle cell disease have an abnormal amino acid composition of hemoglobin, leading to a comformational change to insoluble proteins whenever the red blood cell is deoxygenated; this leads to a change in shape from biconcave to sickle shaped. In sickle cell crisis, the abnormal RBC clump together (easily, because of their shape) then obstruct small blood vessels in the extremities and other organs, causing severe pain.
