The correct answer is option D. Having a Constant In Your Experiment.

The errors in the scientific experiments can occur due to many reasons. The main reason of any error in the scientific investigation is the experimental errors, which include the errors during the data collection and performing an experiment.

Having a constant in an experiment is not a source of error. Constant helps in study the effect of other variables, which are being tested.

exis [7]

Answer:

Do the organism's colls have nuclei?

Explanation:

Protists represent eukaryotic organisms whose cells contain a nucleus and organelles delimited by membranes, whereas Archaea and Bacteria are unicellular prokaryotic organisms that lack a cell nucleus, in which the genetic material (chromosome) is localized in a part of the cytoplasm named nucleoid. Eukaryotic organisms include protists, animals, plants, fungi, and most algae. Most protists are unicellular, although there are species that are multicellular.

How would relaxing the smooth muscles in arteries affect blood pressure ?
zloy xaker [14]
When you relax the smooth muscles in arteries, it affects the blood pressure quite a lot. If you're a up and running person, you're most likely not always relaxed. Although - if you manage to relax, it would cause your blood pressure to lower from a high rate, to a much lower rate. That's the main outcome of this.

What is the difference between the ""one gene-one protein"" and ""one gene-one polypeptide"" hypotheses?
mars1129 [50]

Answer:

"One gene-one protein" hypothesis states that one gene codes for one protein while the "one gene-one polypeptide" hypothesis states that one gene codes for one polypeptide chain of a protein having more than one type of polypeptide chains.

Explanation:

Beadle and Tatum proposed the one gene-one protein concept to explain the one-to-one correspondence between genes and proteins. Accordingly, one gene carries information to encode one protein. Since enzymes are proteins with catalytic power, a gene encodes the information to produce a single enzyme.

The "one gene-one protein" concept was later modified into the "one gene-one polypeptide" hypothesis. According to the "one gene-one polypeptide" hypothesis, one protein may have more than one polypeptide chain. One gene carries the genetic information to encode one polypeptide. Therefore, a protein with more than one type of polypeptide chains will be encoded by more than one gene.
