Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
The molecule produced by light reactions in plants and used by some bacteria for cellular respiration is oxygen. Photosynthesis occurs only in the light, whereas cellular respiration occurs in both the light and the dark. Complex organic molecules release energy during cellular respiration, but they store energy during photosynthesis.
The majority of autotrophs, or organisms that do not rely on external food sources, obtain the majority of their energy from light reactions. These organisms are known as photoautotrophs. When light is present, chemical reactions known as "light reactions" occur. Photosynthesis is the plant-based light-induced reaction.
This is the process of converting light energy into chemical energy. The sun's light energy is converted into the compounds ATP and NADPH during this process (nicotinamide adenine dinucleotide phosphate).

Answer:
Ecosystem diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Biodiversity is important because it clears out our water, changes out climate, and provides us with food.
Explanation:
Well mainly the survival of almost all living organism directly or indirectly depends upon the food made by the plants, with out this it will lead to the death of humans + animals
