Answer:
Answer is C. Bacteria
Certain types of bacteria have a relationship with certain plants where they help convert nitrogen into a usable form.
Explanation:
Nitrogen is abundant in the atmosphere, but plants cannot use it because of the absence of a necessary enzyme, nitrogenase, which converts nitrogen into a usable form. So they form a symbiotic relationship (mutually-beneficial arrangement) with nitrogen fixing soil bacteria (rhizobia) which perform biological nitrogen fixation. Biological nitrogen fixation is a process in which the symbiotic nitrogen-fixing bacteria coverts atmospheric nitrogen into ammonia and organic derivatives that plants can use to synthesize proteins. This bacteria form nodules on the roots of plants like legumes in which nitrogen fixation takes place.
Both plants and bacteria benefit from this symbiotic relationship, as the plant obtains ammonia to synthesize proteins from nitrogen in the atmosphere while bacteria obtain carbon compounds from the plant produced through photosynthesis and a secure environment to grow. As the plant roots leave behind some of the usable form of nitrogen in the soil, this process also increase soil fertility.
Generally speaking, it would not affect the organism. For humans, we regularly replace our cells in our body, so even when our cells die, we are fine.
I think Its the option that says that one of the reactions absorbed more energy because in the diagram the activation energy is shown to be greater for the blue pathway.
Answer:
Option d. None of the above
Explanation:
- Genes do not blend together at the level of genotype. In fact, genotype is a one of its characteristic features.
- The function of gene is to carry the genetic information whereas its the amino acids that code for a protein.
- Genes do not form cluster of genes through mutation, it is formed by divergence gene duplication.
