A molecule is when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements.
Answer:
The correct answer would be A). They will all be blue.
Genotype of the parents are BB and bb.
As both are homozygous in nature so, each will produce only one type of gamete.
BB will produce gamete B and bb will produce b as its gamete.
The cross will results in the production of offspring each with genotype Bb.
We know that blue is a dominant trait and thus it will be expressed in heterozygous condition (Bb).
Hence, all offspring would be blue in color.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then <em>discovered</em>) to emerge is proof of such.
Answer:
b., c., e. are the answers.
Purines have double rings, whereas pyrimidines have single rings.
Answer:
separate DNA fragments according to their size.
Explanation:
Gel Electrophoresis of DNA demonstrates how DNA can be specifically cut into fragments by restriction enzymes and then can be separated by fragment size on an agarose gel.
