Answer:
Biological evolution
Explanation:
<em>Biological evolution is defined as the formation of complex organisms from single ancestral type over a large time period. Evolution believes that all living organisms descended from a common ancestor but not without modification.</em>
There are several evidence to support the theory of evolution including morphological evidence, paleontological evidence, biochemical evidence, among others.
The similarity in the structure and components of DNA of all living organisms is one of the evidence pointing to the fact that living organisms might truly have been from a common ancestor. In addition, all living organisms tend to use ATP largely as their source of energy, giving further credence to evolution theory.
A. Shellfish will disappear first if an estuary was destroyed.
The Incubator made it possible to maintain a controlled environment for cell cultures because most modern incubators act as a petri dish but in a more controlled state.
Answer:
In explanation.
Explanation:
Gregor Mendel formulated his laws of heredity in 1860 before...
-The structure of DNA was known, the existence of chromosomes and genes were known and the mechanisms which create variation in offspring were known.
If your quiz is like this:
Question: Gregor Mendel formulated his laws of heredity in 1860 before ________.
A). The structure of DNA was known.
B). The existence of chromosomes and genes was known.
C). The mechanisms which create variation in offspring were known.
D). All of the choices above are correct.
E). An understanding of mitosis and meiosis was known.
The correct answer is the "D" because yes after Gregor Mendel formulated his laws of heredity in 1860 the structure of DNA was known, the existence of chromosomes and genes were known and the mechanisms which create variation in offspring were known. (Referring that A, B, and C are correct).
Hope this helps.
