Answer: A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.
In the process of photosynthesis the plants in the presence of sunlight, water and carbon dioxide produces a carbohydrates as food and oxygen is liberated into the atmosphere. The process of photosynthesis takes place in day and plants avail oxygen from the roots and leaves for respiration. The food produced is broken down into carbon dioxide and water with the release of energy in the presence of oxygen during cellular respiration. Plants produce oxygen as a byproduct of photosynthesis and use oxygen for cellular respiration.
On the basis of the above information, A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration is the correct statement that describes the relationship between plants and oxygen.
Answer:
Apoptosis is a multi-step, multi-pathway cell-death programme that is inherent in every cell of the body. In cancer, the apoptosis cell-division ratio is altered. Cancer treatment by chemotherapy and irradiation kills target cells primarily by inducing apoptosis.

Explanation:
It should be noted that protein consist of amino acids. There are hundred of amino acids that are contained in protein. Examples of protein include fish, meat, eggs, nuts etc.
The amino acid sequence that can be found in the protein determines the primary structure of protein. The functions of protein include building and repair of body tissues, it also helps in maintain a proper potential of hydrogen (PH) for the body. Lastly, protein is also essential for growth as they help in cell and tissue growth.
Enzymes are catalysts that are responsible for speeding the chemical reaction rate in the body cells. Enzymes help in digestion.
Hemoglobin, is a protein that contains iron that can be found in the blood of animals. The function of the haemoglobin is to help in transferring oxygen to the tissues from the lungs.
The physical appearance of an organism is its phenotype which is determined by genotype and the environment. A phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior, and products of behavior. Genotypes on the other hand are the set of genes in our DNA which is responsible for a particular trait.
