Answer:
A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.
Explanation:
Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.
Answer:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of matter are converted into neutrinos, solar radiation, and roughly 4 x 1027 Watts of energy
Explanation:
To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.
Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.
500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal
From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:
2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
Answer:
stimulates production of red blood cells is a correct answer.
Explanation:
function of the hormone erythropoietin: stimulates production of red blood cells
Erythropoietin hormone is produced by the kidney and its function is to promotes or support the formation of the red blood cells and to provide protection to the cells from the destruction.
Erythropoietin hormone stimulates the bone marrow to produce red blood cells and the function of the red blood cells is to transport oxygen to the body.
Answer:
Decrease
Explanation:
Acceleration is inversely proportional to the mass of an object.
Acceleration decrease as the mass of the object increase
If u use the formula F=ma to calculate, you will get
a=0.5m/s2 for the first situation (m=10kg) and a=0.25m/s2 for the second situation (m=20kg)
