Answer:
Three Domains of Life
The scheme most often used currently divides all living organisms into five kingdoms: Monera (bacteria), Protista, Fungi, Plantae, and Animalia.
Explanation:
if it's a thunderstorm, that means there's lightning, not necessarily a tornado. You're thinking of a tornado. Lightning may strike trees, water, and tall objects, so it's best to stay away from them. The answer is C
Answer:
The team would have to replace the nucleus.
Explanation:
Prokaryotic cells, such as the Mycoplasma capricolum cell used in the experiment do not contain either membrane bound organelles or a defined nucleus. Prokaryotic DNA floats around freely in the cytoplasm in a region called the nucleoid.
The genetic material of eukaryotic cells is protected by a membrane bound nucleus. Therefore, in order to replace an animal cell's DNA, the whole nucleus has to be removed.
Example:
In the process of cloning, the oocyte (egg cell) that receives the nucleus (from somatic cell) of the desired species or individual has to be enucleated i.e. its own nucleus has to be removed. This process is called somatic cell nuclear transfer.
The correct answer is C. Here's why:
Choice A is illogical. A single experiment does not confirm a theory as true. Multiple successful trials are needed for one to even consider a hypothesis to be accepted as a theory.
Choice B is wrong. If a scientist finds a new way to test a hypothesis, experimental methods do change. Note that when there are additional ways to test a hypothesis, a scientist should test it with additional methods.
Choice D is incorrect. If someone finds a way to test a new hypothesis, it would not be made into law since there is more information regarding the theory. This means that it would remain a theory until one can prove that it can't be tested using different methods.
Explanation:
The new research carried out by NASA on mars suggets that many of the Mars' ancient channel have been carved by flowing water, were actually formed by melt water beneath glacial ice sheets. The rocks looked familiar to the rocks found on Earth in these water channels. Moreover, conglomerate rock was found near the base of the channel on Mars.
