Answer:
Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships.
Explanation:
Basically it is a hypothesis from before hypothesis actually were called hypothesis
Answer:
B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.
Explanation:
According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.
Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.
Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.
The correct option is B.
Answer:
Basically, together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
Explanation:
There are two different genotypes of brown labs and three different genotypes of yellow labs (eeBB, eeBb, and eebb) (Eebb and EEbb).
Let's examine genotypes, a different table now: As a result, a brown or yellow lab couple can have both brown labs and black or yellow labs.In actuality, neither brown nor chocolate dogs are permitted. Only yellow puppies can ever be born to a yellow lab couple. Even stranger, two brown labs can have yellow or brown puppies, whereas two black labs can have yellow or black puppies. Only yellow labs are capable of independently producing several shades of colour.
