Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules
Answer:
The answer is b)Betaproteobacteria and e)Gammaproteobacteria
Explanation:
Nitrification, which is defined as the microbial oxidation of ammonia to form a nitrate, plays an important role in the global nitrogen cycle. There are two different groups of bacteria that can oxidize ammonia, as a first step in the nitrogen cycle. These groups are known as the Beta-proteobacteria (genera <em>Nitrosomonas</em> and <em>Nitrosaspira</em>) and the Gamma-proteobacteria (genus <em>Nitrosococcus</em>).
Answer:
Their DNA is organized into chromosomes
Explanation:
The only possible answer from the options provided in the comments is that the DNA is organized into chromosomes. The other options are all false. Animal cells do not contain a cell wall, that is specific to plant cells and some bacteria. Animal cells do not have a single loop that contains all of their DNA, that is a feature of bacterial cells. Eukaryotic cells do have membrane bound nuclei, this is in contrast to prokaryotic cells.
However, eukaryotic DNA is organized into chromosomes
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is
