Paraphrase four safety practices you should always use when you begin scientific inquiry

vovikov84 [41]

Scientific inquiry is asking a question about the world and finding out an answer or explanation in order to develop explanations of natural phenomena in a continuing and creative process. It is very important to follow safety rules during every scientific inquiry:
1.Do not taste, touch, or smell substances unless directed to do so.
2.Wear safety glasses and other required safety equipment.
3. Keep the lab area, including table top and walkways, clear of unnecessary items.
4. Handle all equipment carefully and as directed.

predict if the sensory nerves in a persons foot are nonfunctional, would the person feel pain if the foot was severely burned

irina1246 [14]

Nerves are cells that can detect any type of pressure, movement, or anything of that nature. If we didn't have nerves, we couldn't feel pain. If the nerves in a foot are damaged, you wouldn't feel the pain of it being burned.

The border between the transparent edge of the cornea and the white of the fibrous sclera is the

evablogger [386]

The border between the transparent edge of the cornea and the white of the fibrous sclera is the limbus. The limbus contains clusters of limbal stem cells that help to maintain the corneal epithelium and to regulate corneal transparency and vision throughout life. The limbus also acts as a boundary that protects the conjunctiva and its blood vessels.

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.
