Answer: Draw a conclusion about your hypothesis

Explanation:

If the results match up, then the data supports the hypothesis and thus, the hypothesis itself SUPPORTS the idea that you're studying. Afterward, discuss the experiment with your peers.

Never say that a hypothesis has been proven, because you are not proving anything, it is support.

Which of the following structures is found in both eukaryotic and prokaryotic cells?

Morgarella [4.7K]

C can be taken out of the question as eukaryotic cells do not have a nucleus. A lysosome is is only in prokaryotic cells so B can be taken out of the question. The answer should be D.

What is the difference between an organisms habitats and niche ?

VladimirAG [237]

Organism's habitat (where a species live) can be described as all of the biotic and abiotic factors in the area where an organism lives.
b. Ecological niche (how species live) is composed of all of the physical, chemical, and biological factors that a species needs to survive, stay healthy and reproduce. The niche includes food, abiotic conditions, and behavior.

What type of pressure means the air around you is densely packed?.

uranmaximum [27]

In the atmosphere, the density of air particles decreases with height, with more gas particles remaining near the surface of Earth. When only taking into account humidity, dry air is more dense than moist air because of molecular weights of the gases.

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.
