Answer:
the answer is D. Sea ice forming
Explanation:
When ocean water freezes into ice, the salts stay behind in the liquid water. This increases the water’s salinity, making it denser. The cold, dense water sinks, forming a deep-ocean density current.
Answer:
Its below in the explanation
Explanation:
1.RNA polymerase unzips the DNA molecule.
2.Free RNA nucleotides pair with the complementary DNA nucleotides on one strand of DNA.
3.The mRNA molecule breaks away as the DNA strands rejoin.
Vertebrates:
1) They've got a backbone/spine.
2) Are probably more complex organisms: fish, amphibians, reptiles, birds, mammals (in that order.)
3) Movement is based on an internal skeleton.
4) Wide range of sizes and shapes.
5) K-selected population
Invertebrates:
1) No backbone.
2) Less complex: sponges, worms, mollusks (e.g. snails) , crustaceans (e.i. crabs.) Insects.
3) Movement is not based on an internal skeleton, or some don't move at all.
4) Must be small in size to fulfill their needs for air and nutrients because systems are simpler.
5) R-selected population
The correct answer is a series of distinctive anatomical traits that contrast with archaic traits from earlier hominins.
The study of human evolution focuses on the events which led to the development of the human species <em>Homo sapiens</em> as we know it now. The group of hominins includes the modern humans, extinct human species and our immediate ancestors. Earlier hominins possessed some characteristics which are distinctive from the modern humans.
