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.
It allows scientists to avoid the effects of light pollution
I think it’s all of the above..
Answer: Below
Explanation:
Alligators play an important role in maintaining ecosystem balance. Sitting at the top of the food chain, alligators are top predators and help keep other animal populations in balance. By digging holes and leaving trails throughout marshes, they create habitats for fish and marine invertebrates
The phagocytotic barrier, which is a part of innate immunity best describes the above scenario.
Answer: Option C
<u>Explanation:</u>
The largest organ of the body is the skin, similarly the skin also an immune barrier to the body. If there is any damage in the skin , its pH gets compromised and there it calls in for a microbial attack.
When there is a cut in the skin and bacteria enter the body, the immune system responds. First, macrophages approach the area of the cut. Next, the macrophages surround any bacterial cells and engulf them, the Phagocytosis barrier which is the part of the innate immunity
