Answer:
a radio uses the reflections of a coil of wire placed in a permanent magnetic field.
The chromosome must be duplicated before mitosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. This process first requires the parent call to duplicate all of its genetic material. This ensures that the daughters cells are genetically identical to the parent cell and also the other daughter cell.
This is important because mitosis is used in many cases in living things such as growth, repair, and more. This ensures us for example not suddenly changed to another organism or another characteristic.
Answer:
wouldnt that lead to a variation of the trait?
Explanation:
DNA is a double helix. It is composed of sugar, phosphates, and four different bases: A, T, G, and C. As cells grow, DNA is uncoiled and used to make proteins, but sometimes DNA is different between two bees (or humans) and then different proteins are made. These changes in the order of the A, T, G, C bases can be mutations or natural variations.
Substitution: This is usually just one base that has changed in the sequence.
Addition (insertion): One (or more) base added to the sequence. The surrounding sequence is the same after the insertion ends.
Deletion: One (or more) base is removed. The surrounding sequence is the same after the deletion.
