Answer:
Explanation:
. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.
2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.
3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.
4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.
A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.
5.Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

But DNA is actually in the Nucleic Acid but you might not be learning that yet good luck hun <3
Answer:
my guess is C- to breathe...but the respiratory system also gets rid of waste, but mainly to help a person breathe
Explanation:
hope this helps
Answer:
The closer together different genetic sequences are in the same chromosome the smaller is the chance of crossing-over/recombination among them
Explanation:
Genetic linkage refers to genetic sequences which are located on the same chromosome, and thereby they are usually inherited together during meiosis. On the other hand, crossing over (also known as recombination) refers to the exchange of chromosome fragments between non-sister chromatids during meiosis. In consequence, the closer together two genetic sequences are on the same chromosome, the lesser will be the chance they will be separated by crossing-over.
