The invading microbe or pathogen is called an antigen. It is regarded as a threat by the immune system and is capable of evoking an immune response. Antigens are proteins that are found on the surface of the pathogen.
Which cells allow antigen entry?T and B cells differ in one basic way: whereas T cells bind antigens that have been outlined and embedded in MHC molecules by APCs, B cells function as APCs that bind entire antigens that have not been processed.
Thus, the surface, invading microbe or pathogen is called an antigen. It is regarded as a threat by the immune system and is capable of evoking an immune response.

The leading cause of limited water supplies is _______. a. low precipitation b. overuse c. limiting use d. government please select the best answer from the choices provided a b c d
The leading cause of limited water supplies is low precipitation. Anything will not be limited until a huge production has been created. Hence, overuse, limiting use, and government are not responsible for the cause of limited water supply.
What do you mean by Precipitation?Precipitation may be defined as any sort of water that originates in the Earth's atmosphere and then falls onto the surface of the Earth. It includes snow, rain, hail, dew, etc.
Precipitation is considered the major component of the water cycle that mediates the transport of water movement across the planet. If it declines, the supply of water gets limited.
Therefore, the leading cause of limited water supplies is low precipitation.

Why is the presence of clay particles important in soil?.
Answer:
Tiny particles (humus and clay) are very important for holding plant nutrients in the soil. Clay and humus particles have a negative surface charge. Cations are positively charged. Because opposites attract, the clay and humus hold cations, and prevent them from being leached out of the soil by water movement.

What happens to macromolecules from food during digestion?
What atoms make up sugar molecules, amino acids, and fatty acids?
What do you notice about the atoms that make up these molecules?
How are these atoms used to make new molecules? What types of molecules are
made?
Where does the energy come from to produce these new molecules?
If there is not enough carbohydrate intake, how does the body form glucose?
If there is a glucose shortage, how does the body produce energy?
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.
