Answer:
The incorrect answers are: The moon does not have water and the moon does not have oxygen. Cross them both out.
Explanation:
Answer: Amino acids; peptide
Explanation:
20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.
There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
Answer: Option D.
Explanation:
The process of bone thickening starts with the formation of a template of the hyaline cartilage diaphysis from chondrocytes. Due to developmental signals the bone matrix begins to calcify. This calcification allows the prevention of nutrition diffusion into bone matrix and opens the cavities in diaphysis cartilage. Blood vessels enters into the cavities and osteoblasts and osteoclasts modifies calcified cartilage matrix into spongy bone. Osteoclasts allows the break down of spongy bone and forms a medullary cavity in diaphysis. Irregular connective tissue forms a periosteum (covers compact bone) around the bones and allows the attachment of bone to tissues, tendons, and ligaments. The bone then continues to grow and get thick.
Hence, the correct option is D.

In order to answer your question, you have to look at the equation of photosynthesis, which is one of the basics of biology.
Carbon Dioxide + water = glucose + oxygen
Written as a scientific equation, it would be
Therefore, the products of the photosynthesis chemical reaction would be Glucose and Oxygen. Eliminate A, C, D, and the answer should be B
