Answer:
Stabilizing selection
Explanation:
The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.
During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.
In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.
Thus, Stabilizing selection is correct.
A.)Scientists look for fossils that could be common ancestors on the different
continents, showing that the common ancestor once existed on one or more
False.
Type A has A antigen and B antibody
Type B has B antigen and A antibody
Type AB (aka universal receiver) has both A and B antigen and NO antibodies
Type O (aka universal donor) has NO antigens and has A and B antibodies
Answer:
True
Explanation: These experiments were the first time DNA was accepted as anything other than a protein.
Answers:
Adenine = 21.5%
Thymine = 21.5%
Cytosine = 28.5%
Guanine = 28.5%
Explanation: they must all equal to 100%. Adenine pairs with thymine, so the their amount of bases needs to be equal. Same for Guanine and cytosine.
