Answer:
The law of conservation of mass
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

The function of the respiratory system is to break down food.
RESPIRATORY SYSTEM:Respiratory system is one of the system of living organisms that consists of organs, which functions in exchange of gases in and out of cells. The major organ of the respiratory system is the lungs. However, respiration majorly deals the breakdown of food molecules in the cells. These breakdown of food molecules release energy in form of ATP, which is needed to perform cellular activities. Therefore, the function of the respiratory system is to break down food.Learn more about respiratory system: https://brainly.com/question/3305440?referrer=searchResults

Answer:
12!
Explanation:
Sex cells only carry half of what makes up the organism's DNA. This is so that when they find a mate, in this case- another tomato, their sex cells and their partner's sex cells will add up to the appropriate amount of chromosomes in the organism's DNA. In this case, 24.
How might this change affect the structure and function of the protein?
Answer:
Explanation:
Three-dimensional folding of a protein is due to interactions among the R groups of the amino acids. Cysteine has a sulfhydryl group, which may form a disulfide bridge with another part of the polypeptide chain. Valine has no sulfhydryl group and is nonpolar, which will affect how the polypeptide will fold.

How does the polarity property make hydrogen bonds between water molecules possible?
Answer:
The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. ... As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds.

Lipids are...
A. Protein molecules
B. Similar to water molecules
C. Polar molecules
D. Nonpolar molecules
Answer:
The answer you are looking for is D.
Explanation:
Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. (non- polar molecules)
Lipids are fat molecules and are hydrophobic (water repulsive) in nature. Thus, option D is correct.
What are Lipids?Lipids are important biomolecules and are widely distributed in biological systems. Lipids are organic macromolecules.
Lipids are insoluble in water (polar) and require non-polar solvents mainly hydrocarbons for dissolution like petroleum, ether etc. Thus, non-polar in nature.
Lipids include array of molecules like fats, wax, steroids, vitamins (fat-soluble; A,D, E and K), hormones, oils etc and have diversified functions.
Lipids form an integral part of the cell membrane. It also surrounds membranous structures. It protects the cellular membranes by creating an insulating layer.
Lipids are essential for storing and conserving energy in mammalian body. It helps in metabolism of glucose by converting extra glucose to glycogen in adipose tissues.
Lipids also act as transport molecules in the body. Many lipids function as chemical messengers.
Therefore, Lipids play a pivotal role in living system.
