Which of the following are abiotic factors that shape ecosystems? Group of answer choices

Why is this considered a nonscientific question? "What color is a great horned owl?"

madam [21]

Answer:

The question "What color is a great horned owl?" does not require the scientific method to be used for getting an answer hence, it is not a scientific question. This question does not require any hypothesis or any other method. It can easily be answered by just looking at the horned owl.

A scientific question has to be a question from which a hypothesis can be made. The hypothesis can be tested through experiments and observations. Results and conclusions from the experiments would result in answering that question.

If a deer eats grass, what percentage of energy will the deer acquire from the grass? 0. 1 percent 1 percent 10 percent 100 perc

Lemur [1.5K]

The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.

In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another.
The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.

<h3>What is the position of deer in the food chain?</h3>

The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.

Thus it is clear that 10 percent of energy will the deer acquire from the grass.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

These thin-walled vessels are the only ones through which exchanges are made between body cells and blood.

kvasek [131]

Answer:Capillaries

Explanation: Capillaries are tiny, thin walled vessels that form a network to take blood through the organs and other body tissues. The dense networks of capillaries present a large surface area, which allows materials to be exchanged between body cells and the blood rapidly.
