marta [7]

Answer:

The parents are of genotype heterozygous dominant and homozygous recessive. Supposing the dominant allele is N and the recessive allele is n, one of the parents will be Nn while the other nn. The phenotypic (based on visible characteristics) ratio will be 1:1 for dom/rec and rec/rec

What can you learn about a sample from an sds-page analysis?
puteri [66]

Option <u>(c.) the purity of the protein</u>, will be the right one.

Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.

After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.

It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.

Emily wanted to see what battery lasted the longest. She put each battery into a clock and recorded the time that the clock stop
ryzh [129]

<u>Answer:</u>

<em>A constant is something whose value cannot be changed and is used for comparison purpose. </em>

<u>Explanation:</u>

The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.

However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.

How does social distancing address the density dependent aspect of this disease?
9966 [12]

Answer:

Because your not close enough to get the virus if you have a mask, but if you don’t wear a mask, social distance is irrelevant because the sneeze or cough travels more that 100 feet and then your caught with the virus.

Question 12
Citrus2011 [14]

Answer:

Increasing the surface area of a solid has no effect on the speed of dissolving. Hence, the correct answer is option B.

Explanation:

The increasing of surface area has no effect on the speed of dissolving at as it is irrelevant with the dissolving speed with the solvent. The dissolving effect air speed can be altered with the temperature and with the volume but is increasing of surface area has no relevance on the dissolving speed.

If the temperature is raised above the room temperature it helps in dissolving speed and dissolving quantity. The increase of surface area can we done by various ways such as expanding through mechanical method, etc.
