Answer:
Vision
Explanation:
Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.
Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative in response to the stimuli.
Thus, the correct answer is option (d).
Answer:
The correct answer is - option A. short and less complex.
Explanation:
A food web is a network of many food chains. The food chain is one pathway that describes the path of the animals finds food, it is linear representation. Food web shows all the plants and animals in connection with each other in the food web.
In the Arctic, biodiversity is comparatively low with fewer species of flora and very less number of fauna that include caribou, hare, musk ox pika, and insects are the primary consumers.
Secondary consumer eats herbivores and these organisms are normally are top trophic levels in arctic include fish and polar bear. So the consumers, primary consumer and predators or secondary consumers form a short and less complex.
Thus, the correct answer is - option A. short and less complex.
A. They impede fish migration and spawning
<span>Nitrogen and phosphorous are the most prevalent aquatic pollution and contribute heavily to the excessive growth of algae in aquatic environments called algae blooms. The nitrogen from the fertilizers is found in molecules called nitrates which are compounds of both oxygen and nitrogen. Phosphorous helps algae to absorb carbon dioxide. So when the phosphorous levels are high the algae absorbs more carbon dioxide, which allows for faster photosynthesis and faster glucose production which leads to faster growth. Although algae need both nitrogen and phosphorous to grow, when the levels are too high the algae grows faster than the ecosystem can sustain leading to oxygen deprivation for the other aquatic organisms.</span>
