Answer:
The answer is D. Nucleus are only found in Eukaryotes.
Answer:
<em>X Free nitrogen is in the atmosphere
</em>
<em>Y Producers absorb nitrogen compounds through their roots.</em>
Explanation:
Nitrogen is present in the soil. The plants take up nitrogen along with other minerals as they draw water from the soil. Nitrogen enters the soil when decomposers feed on dead and decaying matter. They breakdown nitrogen and release it into the soil. The plants take this nitrogen from the soil.
The area labelled X shows that nitrogen is present in the air. Nitrogen is one of the abundant gases which is found in the Earth's atmosphere.
The most substantive climatic influence from volcanic eruptions arises from the generation of atmospheric haze. The huge eruption columns administer sulfur-rich gases and ash particles into the stratosphere and troposphere and these clouds can envelop the globe within the weeks of the volcanic activity.
The small ash components reduce the amount of sunlight reaching the Earth's surface and lower average global temperatures. The sulfurous gases add with water in the atmosphere to produce acidic aerosols, which also absorb incoming solar radiation and reflect it back into space.
Charles Darwin; he studied the different beak shapes/sizes of Galapagos finches and found that over time, they changed due to their needs for the food found around them (evolution).
Cancerous cells(in tumors) are in a phase of rapid mitosis(they don’t pass the whole G phase and just divide rapidly).
So mitosis inhibitors would inhibit this rapid division and the further growth of the tumor and progression of cancer in the patient.
