List two types of measurements that you would need to make during the experiment

Biology

Two types of measurement that would be needed to make during experiments are:

i. Instrument measurement – while carrying out an experiment, we need to write the data shown on the instrument in order to infer the results. Even the data in points should be noted.

ii. Measurement of error - no instrument is perfect. Therefore, before starting an experiment we need to measure the error of the instrument. Calculating the error would help in getting approximately correct answer.

An atom that has fewer neutrons than protons and more electrons than protons is a(n) <br> ion.
Elden [556K]

The right answer is Negative (anion).

Anion is an ion that, having gained one or more electron (s), carries one or more negative electric charge (s), (since the number of negative charge (electrons) is greater than the number of charges positive (protons)): for example, the Cl- chloride ion is the chlorine atom that has gained an electron. Conversely, a cation contains fewer electrons than protons.

It is so called because during an electrolysis, this ion is attracted by the positive electrode called anode, in the same way that the poles of opposite charges of the magnets attract.

) You treat some cells with a proteolytic enzyme that is too large to penetrate the cell membrane (Set 1). Another group of cell
Advocard [28]

Answer:

Proten W

Explanation:

SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).

When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).

Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.

What would earth’s surface look like if earth did not have an atmosphere?
Dvinal [7]
Earth would basically look like the Moon; minus the craters, of course. This is because with no atmosphere to hold all of the Oxygen near the surface, all life would die off fairly quickly.
