Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
Answer:
34 calories
Explanation:
One gram of carbohydrates provides total= 4 calories.
2 grams of carbohydrates would provide= 4 x 2 = 8 calories.
One gram of protein provides total= 4 calories.
2 grams of protein would provide= 4 x 2 = 8 calories.
One gram of fat provides total= 9 calories.
2 grams of carbohydrates would provide= 9 x 2 = 18 calories.
Total calories from food that gives two grams each of fat, carbohydrate, and protein= 8 + 8 + 18 = 34 calories.
Answer and Explanation:
The process of transmission of heat due to the movement of molecules in the fluid is called convection. Convection also takes place on a global scale. At the equator, warm and less dense air tends to flow and rise towards the poles. Then denser, cooler air sinks and flow back towards the poles. Due to the rotation of earth rising warm air from the poles does not make it all the mode towards the pole. The combination of the earth’s rotation and global convection makes a series of wind patterns known as convection cells. The earth's rotation also alters the airflow pathway, which causes the wind’s path to be curved as it travels between the equator and poles. In the southern hemisphere, winds turn to the left and move anticlockwise around a high-pressure centre, while in the northern hemisphere, winds turn to the right and move clockwise around a high-pressure centre. The twisting of air currents, due to the rotation of the earth is termed as Coriolis effect. Due to this effect, winds turn to the left in the southern hemisphere. In the northern hemisphere, winds turn to the right.
Answer:
Glycosidic Bonds
Explanation:
Glycosidic Bonds are a type of covelant bond that form between two or more 5 carbon sugar macro-molecules(like glucose). Hydrogen bonds are an attraction between hydrogen atoms, not a real sharing or trading of electrons, as seen with ionic and covelant bonds, while they are essestial to life in water, they generally do not have a strong effect in the building of macromolecules. Therefore, that is incorrect. Phosphodiester, ester, and peptide bonds all occur between different macro-molecules, none of which include glucose(5 carbon sugar). Therefore, the answer is #4.
No, not by choice but it is possible depending on genetic mutations that will happen due to large population of light colored moth.
