Explanation:
Carbon dioxide is a type of colorless gas that is present in the atmosphere in a very trace amount. This gas plays an important role in the process of photosynthesis that occurs in green plants. There are many sources that increase the percentage of carbon dioxide in the atmosphere that has an adverse effect on nature and causes global warming. Car, trucks and many other machines are responsible for the production of carbon dioxide gases directly or indirectly.
Answer:
The correct option is B. The offspring will inherit neither the genotype nor the phenotype change.
Explanation:
Any changes which occur in the DNA sequence of a person are termed as mutations.
Mutations will only be transferred to offsprings if the mutated gene or sequence gets incorporated into the genome of the mutated person.
In the above scenario, the mutation is just changing the person's phenotype and it has not been incorporated in the genotype of the affected person. Hence, the offsprings will not inherit the mutation, nether in their genotype nor the phenotype.
Answer:
Although the question is incomplete, missing options are
- In 1997, they reduced their water consumption.
- In 1996, they planted more trees to curb water pollution.
- In 1994, they used only bottled water for drinking purpose.
- In 1995, they complained about foul odor and taste in water.
Correct option: <em><u>In 1996, they planted more trees to curb water pollution.
</u></em>
Explanation:
Among given options, a clear trend of nitrate level can be seen. <u>Initially, the nitrate level increased in water in first two years (1994 and 1995) and then it decreased significantly</u>.
From the conditions given in the question, the most probable answer is B the plantation effect (<u>phytoremediation</u>). During phytoremediation, <u>plants take up nutrients including nitrate</u> from the water via roots. This nitrogen is then used for the growth and development of plant body mass (e.g. amino acids). As more plants were growing in later years, higher reduction of nitrate was seen. Resultantly, in 1997, the concentration of nitrate was dropped to 7.3 mg/L.
The other options are not correct due to following reasons.
A. There is no information on water consumption in the question
C. There is no information on people's behavior on drinking water lifestyle.
D. Nitrate in the water cannot be smelled or tasted.
