1.<span>If the scientist does a blind study, were he or she does not know which item they are testing </span>
<span>2) Tool used. making sure whatever measurement the investigator is using should be valid and reliable. avoiding the possible results to become biased and unstable due to errors which should be avoided </span>
<span>3) Sampling method. obtain the samples which are appropriate and that would cover the entire participants studied- not a half but the entirely of what you want to study. entirely means as much as the possible sample covers. </span>
<span>4) Have some one else double check your findings. hope that helped</span>
The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.
A deuterium nucleus consists of one proton and one neutron. The quark composition of a deuterium nucleus is
A- 2 up quarks and one down quark
B- 2 up quarks and 4 down quarks
C- 3 up quarks and 3 down quarks
D -4 up quarks and 2 down quarks
The quark composition of a deuterium nucleus is 3 up quarks and 3 down quarks. Thus, option "C" is correct.
<h3>What is the composition of quark?</h3>
The quark composition of a deuterium nucleus is 3 up quarks and 3 down quarks. The overall charge of the deuterium nucleus is +1. Comparing the given overall charge to the chart of the Particles of the Standard Model, the overall charge can be determined from the combinations of the choices.
Thus, option "C" is correct.

Answer:
The correct answer will be option- to make exact copy of the DNA and pass on to the offspring
Explanation:
DNA replication is a complex process which produces the exact copy of the DNA which gets passed on to the generations. The process requires various enzymes and gains its energy from the ATP so is known as ATP dependent mechanism.
The process has to take place before the division of genetic material during cell division cycle so it takes place during S or synthesis phase of the interphase of the cell cycle.
Since DNA replication produces exact or replicated copies of the genome in organism therefore, to make an exact copy of the DNA and pass on to the offspring is the correct answer.
