It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.

The substance used to separate the proteins from the dna
Genrish500 [490]

DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.

<h3>What is centrifugation?</h3>

Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.

It is the frequently applied techniques in the molecular biology laboratory.

The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.

Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for suppor
omeli [17]

Answer:

<u>A. red blood cells containing malaria</u>

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>

What do crops of the green revolution need in order to produce higher yields?
Airida [17]

Answer:

These crops where improved  with technology, production of high-yielding variety, and improve farm practices. All these ensured  the crops of green revolution had increase yield.

Explanation:

Through  genetic engineering, high-yielding variety of cereals e.g wheat, maize, rice, were genetically engineered so that certain features which enhanced increased productivity were selected for.

Use of fertilization, the adoption of mechanization,good cropping and farming system are other factors which enhanced yield of these crops. Specifically, these crops were modified to enhance their Nitrogen uptake, which promotes rapid growths.
