Answer:
Assimilation
Explanation:
Plant roots absorb ammonium ions and nitrate ions in the process of assimilation to use these ions to make molecules like <em>DNA, amino acids, and proteins</em>.
Animals cannot absorb these ions directly; hence they need to consume these plants for the nutrient supplies.
IT IS NOT POSSIBLE to produce malleable cast iron in pieces having large cross sectional dimension. This is because, iron has a very rapid cooling rate and it will not be possible to achieve this rate at different cross sectional areas in a sheet of iron.
Answer:
True
Explanation:
The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.
Answer:
The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.
Explanation:
During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.
