Answer:
A. True
Explanation:
We continuously use drugs and antibiotics against the micro organisms. In the course of time, some microbes may develop resistance against these antibiotics by bringing changes or modifications in their structures. Those which become resistant, survive the selective pressure and hence selected by the nature. Hence developing drug resistance by microbes is also an example of natural selection.
Similarly herbicides and pesticides resistance developed in weeds and pests respectively after prolonged use of herbicide and pesticide is also an example of natural selection which supports the process of evolution.
Answer:The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.
A is volcanoes. They are formed by molten rock emerging through cracks or weaker areas in the crust of the Earth, the molten rock then cools into solid rock. This happens several times and the volcano gradually builds up in many layers, sometimes (like in the photo) this is enough for the volcano to break through the surface of the water e.g. Hawaiian Islands.
Answer:
it is expected to have shorter telomeres
Explanation:
with aging, telomeres activities reduce resulting in shortening, thus, since the nucleus was replaced with an older one, it is expected that the telomeres length will shorten.
Answer:
2 H202--> 2 H2 + 2 02
Explanation:
The reaction corresponds to the decomposition of hydrogen peroxide (hydrogen peroxide) resulting in oxygen and hydrogen products.
