According to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.
<h3>What is Relative dating?</h3>
It consists of ordering fossils or events in a proper formation sequence from the oldest to the most modern, it tends to be used as a method for making chronologies, the ordering of events, fossils or rocks.
Since it does not give an exact or approximate date, they can only give us a fairly long period of time, or in their case a temporal ordering of the fossils.
Therefore, we can conclude that according to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

Answer:
D
Explanation:
because Weight is heavy something is and mass is how heavy
This is an example of <u>recessive epistasis</u>.
Here the presence of recessive allele ee at one locus inhibits the phenotypic effect of genes at the B locus.
As it is mentioned in the question above the ee__ genotype develops into a yellow lab.
Dominant B gene can produce the black coat color phenotype only when a dominant allele E is also present.
If the genotype is B_ee, then yellow coat color would be produced.
Therefore the recessive allele e in homozygous ee form masks the effect of the dominant B allele.
Recessive epistasis is the phenomenon in which the expression of one gene pair is depending on some other gene pair. In different words, one gene must be grown to become one for any other gene to be expressed.

Answer:
The correct answer will be option A.
Explanation:
Humans in history have always tried to organize the diversity of organism based on a number of characters like ecological functions, habit, habitat and others based on the similarities and dissimilarities.
The traditional way of classification has classified the organisms based on the morphological characters but the modern concept of a classification approach to classify the organism based on their evolutionary relationship as a grouping in this way not only organizes the animals but also conveys the information about the understanding of their evolution and evolutionary history.
Thus, option A is the correct answer.
Answer:
Biodiversity conservation
Explanation:
<em>Biodiversity conservation means the protection of different species of organisms present around the world due to their potentials to be a source of drug, food, industrial materials or other important human use.</em>
Several important species that could have been a source of food or other important materials have gone extinct either naturally or due to direct/indirect human actions.
Assuming rosy periwinkle has gone extinct, there is no way its extract would have been discovered to be a good treatment for cancer.
<em>Hence, biodiversity conservation or preservation are efforts put in place to preserve organisms that will serve as our future heritage.</em>
