Answer:
The composition of the stars
Explanation:
Concordance = presence of the same trait.
Identical twins have a higher rate than fraternal because most of their DNA is identical, it’s identical because the zygote split into two so the babies shared an amniotic sack. (Zygote is fertilized egg) so the baby got duplicated meaning only one egg and sperm created two babies. Fraternal twins happen when two eggs are fertilized and grow in separate amniotic sacks. So two different babies, two different eggs and sperm.
Answer:
The correct answer is option c. "adaptive radiation".
Explanation:
The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.
