Answer:

d) Neither accurate or precise

Explanation:

Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

The wording of this is confusing. I think it’s A and B and I’m hesitant say that it’s also C but only if you know the mutation and the gene.

Also for A you would only know a partial sequence of the gene.

kogti [31]

Answer:

MARS

Explanation:

Mars represents the 4th planet of the solar system, being next to the earth. It is comprised of a hard and solid surface and the average surface temperature of Mars is extremely cold, which is roughly about -60°C. The atmosphere of Mars is very thin, which is dominantly comprised of CO₂ gas (almost 95%), along with some molecular Nitrogen (3%) as well as there is the presence of Argon (2%). In addition to this, it is also composed of dust clouds within its atmosphere. There is the absence of a magnetic field in Mars, due to which the solar wind highly affects the atmosphere of Mars.

Andre45 [30]

Intelligence is most likely to be the criteria for random mating in humans.

Explanation:

If random mating is taking place on the conditions that no evolution is taking place the genetic pool will be maintained through generations.

Random mating will be based on intelligence in humans because this is the trait which gets exhibited only when showcased otherwise remains hidden while other characters like personality, appearance and athleticism are phenotypically expressed character.

Random mating is not under the influence of genotype. Intelligence is a trait which needs to be more in human as random mating takes genotype frequency in consideration.
