<u>Answer:</u>
Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.
Option: (B)
<u>Explanation:</u>
- Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.
- When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.
- Amino acid is building block for DNA which tends to the generation of organism.
- Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.
<span>The hypothesis has to survive all attacks on it and continue to provide the best known explanation of the known data.
In the scientific method, there are several steps towards the creation of a hypothesis and eventually a theory.
1. Gather data.
2. Construct a hypothesis that explains the data. This hypothesis should be capable of being disproved and should be capable of making predictions.
3. Gather more data. DO NOT cherry pick only that data which supports the hypothesis . If data is uncovered that contradicts the hypothesis , revise or replace the hypothesis.
4. After the hypothesis has survived all attacks on it and is the best known explanation of the data, then it becomes a theory.
5. Note, data collection continues after the hypothesis became a theory and if new data is discovered that is in conflict with the theory, then the theory is modified, or discarded in favor of a new hypothesis or theory.</span>
Answer:
Yes or no
Explanation:
If the disease is genetic then the answer is yes because identical twins have the same genes.
If the disease is viral or bacterial than the answer is no because identical twins are growing in a different environment and facing different bacteria and viruses. So if one is sick it's not compulsory that the second one is also sick it purely depends on the environmental conditions.
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
<span>The nurse's priority is to assess the patient, including vital signs. If the nurse detects that the labor is progressing, she should notify the physician. She should also determine whether the patient is due for pain medication and determine what she is able to give at that time period.</span>
