The answer bilaterally symmetrical. Bilateral symmetry means that an object is equally divided in half along its central axis.
set the fish in somewhere to rest it on and squeeze the liquid out of the fish, then put the liquid into a test tube and mix it with water, wait and then look at it.
Here is the correct flow chart: GENE > DNA > CHROMOSOMES > NUCLEUS.
The cell nucleus contain chromosomes which are made from long DNA molecules. A gene is a short section of a DNA which codes for a specific protein.
D. Learned behaviors do not directly affect natural selection because they are not inherited.
This is true because learned behaviors can be taught to the offspring but do not come within them the way instincts do.
Answer:
A) The two strands of a DNA molecule are parallel and complementary.
Explanation:
DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.
DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.
In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.
