Answer:
Ca has 20 protons, so neutral it would have 20 electrons, but according to the charge, 2 electrons have been lost.
Explanation:
Answer:
Anabolic.
Explanation:
The metabolic reactions of the body are important to maintain the physiology and homeostasis of the body. Two main types of reaction in the body are catabolic reactions and anabolic reactions.
The anabolic reaction is the reactions that are involved in the formation of the large molecules from the simpler substances. The anabolic reactions are involved in the growth and repair process as complex protein and factors are required that can only be obtained by the anabolic reactions.
Thus, the correct answer is option (3).
The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.
Answer:
Nucleic acids
Explanation:
Nucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA.
Answer: <span>B) Plant trees along canals and roadways on their property to filter runoff and prevent soil erosion
--------
The roots of trees help prevent the soil from being easily eroded by holding the soil in place and taking up the water. The other choices, A, C, and D would cause further erosion by removing objects that would stop the rain or by aiding erosion due to gravity.
