The answer is c)movement of material within earth’s core
Answer:
(A) speciation.
Explanation:
Shrinking of water bodies and development of deserts since the Pleistocene ice age produced new vacant niches that could be inhabited by organisms such as fishes. Production of new isolated streams, ponds, and springs allowed the fishes to occupy these new water bodies. Accumulation of genetic variations to become adapted to their new habitat resulted in the evolution of several new species of fishes with many different genetic traits. This represents speciation due to geographical isolation.
Answer:
Simpe dominant- recsive
Explanation:
"Some people with hitchhiker’s thumb may have acquired two recessive copies, or alleles, of the gene that determines thumb straightness"
Explanation:
Mutations change an organism's DNA and affect how it looks, how it behaves, and its physiology. A change in an organism's DNA can cause changes in all aspects of its life.
Mutations are essential to evolution; they are the raw material of genetic variation.
Answer:
1. equilibrium
2. natural
3. Negative feedback
4. associated processes
5. Continental drift
6. Feedback loops slow the progression of climate change because the positive and negative feedback loops counteract each other. When the weather systems are getting too strong through positive feedback loops, they start to weaken through negative feedback loops.
