When a glacier melts, the ocean level rises therefore causing flooding and creating alien environments for those species that either live near the glaciers or on them.
Answer:
Replication, transcription, translation (it’s the central dogma of biology)
Answer:
'Gametes are formed through a process of cell division called meiosis. This two-step division process produces four haploid daughter cells. Haploid cells contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote.'

The question lacks options, the options are:
A. understand the viewpoint of other people.
B. realize that the term heavy describes an object one way and the term big describes it another way
C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
The answer is C
Explanation:
Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.
However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.
He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.
Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.
Answer:
Complementary base pairing
Explanation:
DNA probes are the single stranded stretches of nucleotides that are complementary to the original strand. DNA probes are used in various molecular technologies like polymerase chain reaction and DNA finger printing.
DNA probes can only hybridize with the specific complementary base pairs. Hence, complementary base pairing determines the specificity of DNA probe.
Thus, the correct answer is option (D).
