Answer:
Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Explanation: I hope this is right?
Answer:
Abiotic- non-living thing. ex: wind,water,soil,sun, atmosphere, temperature
biotic- living components of an ecosystem ex: animals, plants, bacteria, fungus
Energy is passed between organisms through the food chain. it first starts with the producers which get eaten by the primary consumers. than the secondary consumers eat them.
Explanation:
If there were no secondary consumers, there would be an increased population ofprimary consumers. Since primary consumers are herbivores, they would be eating plant life (producers) at a much higher rate.
Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves.
Answer:
Cells grown in culture tend to adhere to each other, through adhesins, so they are able to communicate with each other. They form gap junctions that allow the cytoplasm of the cells to exchange some molecules such as cyclic-AMP associated molecules in this case.
Therefore even though the FSH binds to the receptors on the ovarian follicle cells only (since these are the cells that bear the receptors for the hormone on their surface), the pathway and associated molecules for secondary messengers can diffuse across the across the gap junction into other cells, including those of the cardiac cells, hence inducing some contraction in these cells, as they respond to the secondary messengers.
