The sequence of bases on the other half of the DNA molecule would be CTAATGT from left to right, because each cytosine base pairs with a corresponding guanine base, and each adenine base pairs with a corresponding thymine base.
The appropriate answer is C. ANCESTRAL FINCH. The study of these birds on the Galapagos island led to Darwin proposing his theory of natural selection. Darwin collect and preserved samples of the finches he observed while on his travels.
He did not observe anything unique about the birds until after he returned home. He focused on the differences in the beaks of the birds. It is then that he started to work on his revolutionary theory.
B - Because an active cell can only work if it has a 3-Dimension structure.
Answer:
Abiotic components of an ecosystem are water, air, light, soil, and temperature.
Now think about how the availability of these things will affect what could live in a specific area.
Consider a desert ecosystem. Deserts are arid, receiving little rain (water) and have extreme temperatures (both cold and hot). Because of these conditions only certain plants and animals can live here. These plants and animals have adaptations that are specific to the environment. If you were to put an organism that does not belong in there, they would most likely die out.
Tidbit for you. The Atacama desert is one of the driest places in the world, located specifically in Chile. At one point, this place did not receive any rain for 500 years! Still plants and animals are able to live in this area. When it finally did rain, the sudden downpour caused a radical change in this ecosystem. You would think at first rain would be good, but no. Because the changes the rain brought was too drastic, it caused a devastating effect on the organisms that lived there because they were not adapted to rain.
Animals dont need to breed to survive for themselves, but they do need food, water and shelter
is that whats being asked? this is a bit confusing
