During an experiment, Harry enclosed two leaves of a plant in glass flasks labeled A and B. Flask A had water and carbon dioxide
Evgesh-ka [11]
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.

________ transmit pain that is sharp, nonchronic, and well localized. A. A-delta fibers B. B-delta fibers C. C-fibers D. D-fiber
nydimaria [60]

Answer;

A. A-delta fibers

A-delta fibers transmit pain that is sharp, nonchronic, and well localized.

Explanation;

-The information about touch and pain is transmitted to the spinal cord and brain by primary afferent axons - these are the nerve fibers connected to the different types of receptors in the skin, muscle and internal organs.

-The different nerve fiber groups are; A-alpha, A-beta, A-delta and C-nerve fibers.A-alpha, A-beta and A-delta nerve fibers are insulated with myelin. C-nerve fibers are unmyelinated.

-A-delta nerve fibers carry information related to pain and temperature. A-delta nerve fibers can conduct action potentials as fast as a sprinter in the Olympics.
