The structures help both plant and animal cells meet the challenges of life is nucleus and cell membrane. Thus, option B is correct.
Nucleus is the main cell organelle and the main function of the nucleus is to control and coordinate all the function of the cell. Nucleus is known as the brain of the cell and it has been present in the center of the cell. The color of the nucleus is black in color.The main function of the cell membrane has to keep away the toxic material out of the cell.
Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. Nucleus is known as the brain of the cell and it has been present in the center of the cell. The color of the nucleus is black in color.The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane that contain the channels as well as receptors that give the permission to only selective permeable membrane to enter into the cell.
Therefore, The structures help both plant and animal cells meet the challenges of life is nucleus and cell membrane. Thus, option B is correct.

B. conducts electricity
C. attracted to a magnet
D. high melting point
Answer: The correct answer option (A).
Explanation:
Chemical properties are the properties which are observed in a chemical reaction like change in arrangement in atoms or change in identity of the substance.
Metals reacts with acid to form salts and hydrogen gas. In which chemical composition of pure metal changes during the chemical reaction. So, yes it is a chemical property of metals.
Whereas conducting electricity, property to get attracted by magnet and high melting point doesn't changes the arrangement of an atoms which means they are not chemical properties of metals but are physical properties of metal.
Hence, the correct answer option (A).
answer is react to acid

Answer: Grow ; Disappear.
Explanation:
The organism that best suits in the environment is likely to grow and reproduce and its population in the environment increases.
Over the time the characters that are favored more survive and the characters that does not allows the organism to survive in harsh conditions are not favored.
These organism die and over the time the traits disappear from the population.
