The best way to increase validity of data in an experiment is by performing the experiment numerous times and obtaining measurements and data upon each run of the experiment.
Answer: 2. Each subunit represents a separate polypeptide chain, while one polypeptide chain may contain several domains.
Explanation: Each subunit constitutes of one polypeptide chain. A polypeptide chain has one particular gene coding for it. thus it simply implies that a protein must have one gene for each subunit.
Many proteins is made up of different protein domains. A particular domain may appear in a variety of different proteins.
domains are stable on there own, they can be exchanged via genetic engineering between one protein and another.
Answer:
"pumps blood against a greater resistance" that the answers. hope this helped
Understand latitude. latitude measures how a point is north or south of the equator. now understand longitude, longitude measures how far a point is easy or west of the prime meridian. understand how they appear on a map. now, i’m not the best at helping or explaining, so if this doesn’t help... then hopefully someone else answers for you.
A control group is going to be something that you don’t “experiment on or change. It is grown or watched under normal conditions. This way you have a medium to say how things are “supposed” to go.
The experimental group is going to be where you “experiment” and change the normal conditions to see what outcome will occur ( under different conditions then normal )
