What are your answer choices?
Answer: Answer below
Explanation: pH is a measure of the acidity or alkalinity of a solution. What the pH scale measures is basically the concentration of hydrogen and hydroxyl atoms in a solution. So, the last option is the answer. Another thing to keep in mind is solutions with a pH under 7 are acidic, solutions with a pH of 7 are neutral, and solutions with a pH over 7 are alkaline or considered a base. I hope this helped! Good luck:)
Answer:
carbon dioxide + water → glucose + oxygen
Explanation:
Photosynthesis is the process that plants use to make food.
Think about what you need to grow a plant.
It needs <u>water</u> for sure.
Plants and humans both need air. Plants "breathe" in <u>carbon dioxide</u>, which is what we breathe out. (That's why people say to plant more trees, because they take in carbon dioxide.)
Plants use photosynthesis to make food. The food is called <u>glucose</u>, which is a form of sugar.
Plants "breathe" out <u>oxygen</u>, which is what we breathe in. (Remember trees give us oxygen.)
You might also see the equation as a formula:
CO₂ + H₂O → C₆H₁₂O₆ + O₂
Carbon (C) dioxide (O₂)
Water, or dihydrogen (H₂) monoxide (O)
glucose (C₆H₁₂O₆)
oxygen (O₂)
Sex hormones, since they are responsible for developing secondary sexual characteristics.
Answer;
-Antigen presenting cells
Explanation;
-Helper T cell and inflammatory T cell TCRs recognise epitopes displayed by MHC class II molecules on the surface of antigen-presenting immune cells, including: macrophages that engulf foreign particles such as bacteria; dendritic cells that present antigen to T cells; and B cells that produce antibodies.
-Antigen-present cells APCs engluf antigens, present fragments of antigens to be recognized by T cells
. Major types; dendritic cells in connective tissues and epidermis, macrophages in connective tissues and lymphoid organs &B cells.
