Ierofanga [76]

<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

 

<span>
</span><span>The aim of the pyramid is to recommend ideal  rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>

4. In a class experiment to determine information about free-fall acceleration, a watermelon and a pumpkin are each set to fall
bogdanovich [222]

A)

Answer: They will fall at the same time.

Explanation: This is a free fall equation. Free fall equations don't use other factors such as air resistance or wind.

B)

Answer: 15m

Explanation:

Given: Vi = 10m/s

           t = 1s

           a = 10m/s/s

The equation you need to use is d = Vit + 0.5at^2

d = Vi t + 0.5 a t^2

d = (10 m/s) (1 s) + 0.5 (10 m/s^2) (1 s)^2

d = (10 m) + 0.5 (10 m/s^2) (1 s)^2

d = (10 m) + (5 m/s^2) (1 s)^2

d = (10 m) + (5 m/s^2) (1 s^2)

d = (10 m) + (5 m)

d = 15 m

What the seven steps of the water cycle and define each step
Naddik [55]
The first step of the water cycle is evaporation. It is the process where the water at the surface turns into something we call water vapor. The second step is condensation. This is the process when the water vapor turns into ice/water droplets. The third step is sublimation. It is the process of when the ice directly converts into water vapor with out turning into liquid water. The forth step is precipitation. This is when the clouds pour down due to temperature or wind change. The fifth step is <span>transpiration. When the water sinks into the roots of the plant, the transpiration process is similar by when liquid water is turned into water vapor the the plant. The sixth step is runoff. This is when water runs over the surface of the earth. The final process is infiltration. This is if some of the water does not runoff into rivers, the water seeps into the ground and increases the level of ground water table.</span>
