Answer:
A. Plants
Explanation:
Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.
The reasons why the wastewater reclamation plant will be implemented are the well-being of the environment, as well as making the water suitable for usage for the people. By installing the plant, the wastewater will be cleaned in most part. That will mean that the water can be returned to the nature without it causing damage to it and polluting it, but instead contributing to its well-being and proper functioning. Also, part of the water will be used for irrigation, as flushing water in the toilets, for doing laundry, which will result in preserving the freshwater reserves while still having a source of water for certain needs. The fact that the water will be cleaned, also means that the local water bodies will be safe to use for recreation, as they will not be polluted.
Answer:
the competition between organisms is direct.
Explanation:
An example is the aggression display between competing organisms. This applies to both intraspecific and interspecific competition. In intraspecific competition, the competing organisms are of the same species.
Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
