<span>All natural disasters affect the ecosystem. They affect lands, forests, and coasts and cause death to people, plants and animal species, the spread of invasive species, and loss of habitat. In the short term, they cause climate change but over time, there are some types of natural disasters that increase biodiversity in the long run. Examples of these are earthquakes, landslides, volcanic eruptions, and wildfires. They play an important role in rejuvenating the ecosystem that they once destroyed.</span>
In this question, let us cite one specific example:
<span>1. </span><span>Volcanic eruption. The eruption has an immediate negative effect on surrounding, but through primary succession, the forest begins re-colonization almost immediately. Many plants, insects, and animal species arrive from adjacent places to take up residence. These life forms are adapted to survive in the severe conditions following volcanic eruption causing a new and more diverse forest ecosystem that will last a 150 year period.</span>
The sperm start travels in the seminiferous tubules of the testes where spermatozoa are born, and then transport to the epididymis which sperm passes to the vas deferens and it ended at the utero-tubal junction where egg fertilizes in the fallopian tubes.
Answer:
The correct answer is D. involves proteins in plasma membranes.
Explanation:
Animal cells have several types of proteins embedded in their cell membrane. These proteins play an important role in the transport of molecules, cell recognition, and cell communication.
Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.
These proteins are important for proper growth and development of the cell. Therefore the correct answer is D. involves proteins in plasma membranes.
Answer:
Explanation: The first Australopithecus fossil was found in a lime quarry at Tuang, it was found by Raymond Dart in November 1924.
Answer:
The answer is given below.
Explanation:
Rescorla explain this finding by stating that the tone experienced by the group of rats just before each of 20 shocks was a reliable predictor of the shock for the first group.
The psychologist Robert Rescorla stated in his famous classical conditioning experiment that 2 stimuli does not produce the same level and kind of conditioning. Conditioning works in a better way, if the conditioned stimulus will act as a reliable signal that projects the appearance of an unconditioned stimulus.
