Answer:
Symbiosis
Explanation:
Another category of interactions between organisms has to do with close, usually long-term interaction between different types of organisms. These interactions are called symbiosis
Answer:
Robinson explains how she uses layers in fossilized corals to understand what the environment was like overtime. By finding out what mainly makes up each layer and finding out roughly how old each layer is, she can begin to understand what the chemical composition and climate was like when the coral pieces were alive
Answer:
The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".
Explanation:
There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
Answer:
I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.
Explanation:
The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.
As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.
The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
