The answer here is THE LEAF IN FLASK B WILL NOT GET CARBON DIOXIDE TO MAKE GLUCOSE. In order to carry out photosynthesis, plant needs several ingredients. It needs chlorophyll, the green coloring pigment in plants, sunlight, water and carbon dioxide. To nurture growth, plant needs a favorable medium (usually good soil but there are also those that can grow attached to another plant and those called aerial plants) and nutrients. Carbon dioxide is one of the most abundant gases in the atmosphere. It plays an important role in both plant (photosynthesis) and animal (respiration) processes. In photosynthesis, green plants convert carbon dioxide and water into food compounds such as glucose and water. The oxygen released during photosynthesis is needed by animals, human also, for respiration. Potassium hydroxide, on the other hand, is an inorganic solid compound which absorbs carbon dioxide. During experiments, plants placed inside a solution with potassium hydroxide will test negative in starch test. Absence of starch is attributed to the absorption of carbon dioxide by potassium hydroxide. Photosynthesis did not happen because of the absence of one of its ingredients which is carbon dioxide,hence absence of one of the end products, starch.
I think metastasis is a secondary tumor in a different part of the body that arises from a cells from the primary tumor. Metastasis means the spread of cancer cells. Cancer cells may break away from a primary tumor and enter the bloodstream or lymphatic system and is then spread to other parts of the body.
Answer:
The correct answer is option D. the adaptive immune system.
Explanation:
The adaptive immune system is the immune system that takes place after the first exposure to a specific antigen either from vaccination or a pathogen. Adaptive responses are of two types: the cell-mediated and humoral immune response, the cell-mediated immune response occurs with the help of T cells, and where is humoral immune response is B cells and antibodies.
Vaccination targets the adaptive immune system as they produce antibodies against the pathogen provided by vaccination.
Thus, the correct answer is option D. the adaptive immune system.
