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 %
Answer and Explanation:
Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth
. The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting
. Even though fewer offspring are produced through this method, their survival rate is higher.
Answer:
Excretion is the removal of material from one living thing, for example. Humans excrete tears, sweat, carbon dioxide etc.
Secretion is the movement of material from one point to another, for example. Humans secrete enzymes, hormones, saliva etc.
Basically in summary excretion is the removal of physical material and secretion is the movement of biological materials from one point to another.
I hope this was clear enough lol
