They need more nutrients/food than their bodies can absorb through the skin and they can eat more by actually consuming physically.
Answer:
Nitrogen can be transformed into a utilizable form like NO2 by the fixation process.
Explanation:
The conversion of nitrogen into various chemical forms is described through the Nitrogen cycle. The nitrogen of atmosphere is less usable. However, it can be made usable by various interactions of complex genes that allow nitrogen conversion by different organisms.
One such interactive process is of Fixation. In this method, nitrogen is modified into ammonia by symbiotic microorganism. They have the enzyme called nitrogenase which makes the bond of hydrogen with nitrogen to make ammonia.
D can be eliminated because the temperatures where changed in 3 ways, not two.
A is true, but doesn't apply to the actual experiment "design"
B we don't know for sure, it just looks like a cup/glass.
Best answer for you: C
C is true- it was tested with a single independent variable (one that does not change) on multiple trials (the different temperatures)
The question is incomplete as it does not have the options which has been provided in the attachment.
Answer:
Option-3 and 4
Explanation:
In the given question, the table of the different nitrogen bases of a different organism has been provided in which the number of bases has been mentioned.
In the table, the amount of thymine is almost similar or equal to the adenine while the number of guanines almost equal to the cytosine for a particular species. This data follows the Chargaff postulates which state that adenine bind thymine and cytosine bind guanine therefore the number of complementary bases will be equal.
Thus, Option-3 and 4 are correct.
