Answer:
B
Explanation:
Warm because land gains heat faster than water when heated by the sun. The heated land then transfers the heat to the atmosphere. The air mass is dry becasue a continent is mainly land and very little water (unlike oceans). There is, therefore, very little moisture in the continental tropical air mass.
Answer:
a,the ability to go from a single cell to multicellular organism
<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The other
type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted horizontally
parallel to the ground. It is constantly aligned with the wind using a
yaw-adjustment mechanism. This mechanism moves the entire rotor left or right
in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. </span>
Answer:
The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).
Explanation:
Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.
Here, Anna consumed 7 grams of fat (in salmon)
, 36 grams of carbohydrates (in sweet potatoes and asparagus) and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.
Therefore, total calories in 7 grams of fat is 
kilocalories.
Total calories in 36 grams of carbohydrates is 
kilocalories.
Total calories in 27 grams of protein is 
kilocalories.
Therefore, the total calories Anna consumed for dinner is 
kilocalories i.e., 
kcal.
The calories that came from proteins is 
calories i.e., 
kcal.
