Answer:
Option C is correct. The flow chart best shows the relationship between the cell structures is:
DNA → gene → chromosome → nucleus
Explanation:
DNA can be described as the material of inheritance.
A gene can be described as the basic unit of inheritance. It is made up of segments of DNA.
Chromosomes can be described as thread-like structures which are made up of different genes.
The nucleus is the site where chromosomes are placed. The nucleus is found in every eukaryotic organism.
Hence, the correct order for these cell structures is illustrated in option C.
Answer:
Cancer is related to the cell cycle bc, cancer cells mutate. Cancer is unchecked cell growth. Mutations in genes can cause cancer by making cell division rates go up faster or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor

Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
a proton located in the atom is the nucleus
