Answer:

a. Fiber

Explanation:

The major nutrients required by humans in food are carbohydrates, proteins, fats, vitamins, and minerals. Our food also has dietary fibers and water. Dietary fibers or fibers are also known as roughage. Fibers are present mainly in plant products such as whole grains, pulses, fruits and vegetables. Fibers only add bulk and do not provide any nutrients to us. However, dietary fibers help the body get rid of undigested food.

The color distribution for a specific population of lizards is 170 blue, 50 turquoise, and 30 green. a. The allele for the color
Colt1911 [192]

Answer:

Frequency of BBBB genotype = 0.68

Frequency of BBBG genotype = 0.2

Frequency of BGBG genotype = 0.12

Explanation:

Genotype frequency = number of individuals of that genotype/ total number of individuals

In this population three types of individuals are present: blue, turquoise and green.

Frequency of BBBB genotype (blue) = 170/ ( 170 + 50 + 30)

= 170/250

= 0.68

Frequency of BBBG genotype (turquoise) = 50/250

= 0.2

Frequency of BGBG genotype (green) = 30/250

= 0.12

¿Cuál es la importancia de la fusión nuclear? What is the importance of nuclear fusion?
Rama09 [41]

Without it, there are no stars, including our own sun, and there wouldn’t be us talking about it.

It is used in particularly destructive bombs.

At a tiny scale, it can be used to produce neutrons, eg, a Farnsworth Fusor.

At a large scale, we have yet to figure out how to make controlled fusion work in a way that runs for a long time and generates collectible power we can use to feed the process. This has remained elusively 20 years out from the current state of affairs for 50 years.

If it was made to work, then it would probably be a good source of clean energy that would be safer than many of the non-renewable alternatives.

I don’t expect to live to see it happen.
