What are “cones” in the eye and what do they do?
dusya [7]

Answer:

Cone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes (e.g. the human eye). They respond differently to light of different or color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light. Cones are mostly in the center of your retina. They help you see color and fine detail.

Study the diagram below. In which order does oxygen flow through the human circulatory system?
anyanavicka [17]
The order of flow of oxygen within the human body may be described simply. Oxygen first is inhaled through the nasal cavity and then passes through the trachea, through the bronchi and into the lungs. In the lungs, the oxygen is passed into the blood stream through the alveoli and then is carried to the heart. The heart pumps this oxygenated blood throughout the body, primarily to organs and muscle cells, where it is consumed in respiration and is converted to carbon dioxide and excreted.

Refer the the graph below showing the absorption spectrum of chlorophyll a. Explain what the graph is showing
Stella [2.4K]

Answer: The graph shows that chlorophyll a absorbs light principally around 420-450 nm and 650-680nm wavelengths

Explanation: Chlorophyll a is a pigment found in plants that traps light energy for use in photosynthesis. Chlorophyll a absorbs light mostly in the blue and orange-red wavelengths. This is shown in the graph, where the peaks are around the 400nm and 600nm wavelengths, corresponding to blue and red in visible light.

This absorption means the pigment is 'excited' by this light, sending into a higher state if energy which provides energy for the reactions of photosynthesis.
