I believe the best answer is A.
People are more afraid in fossil fuels running out rather than the other reasons that don't really affect the people today. Hope it helped!!!
Answer:
64
Explanation:
Nitrogen combines directly with oxygen at very high temperatures to form nitrogen(ii) oxide. This is the reaction that occurs during lightning flashes. Atmospheric nitrogen and oxygen combines during the high temperatures obtained in lightning flashes to form nitrogen (ii) oxide.
Equation of the reaction is given below:
N(g) + O(g) ---> 2NO(g)
From the equation of the reaction, 1 mole of nitrogen gas combines with one mole of oxygen gas to produce 2 moles of nitrogen (ii) oxide.
Therefore, 2 moles of oxygen gas will react with 2 moles of nitrogen gas
Mass of oxygen gas that is 2 moles of the gas is obtained from the formula; mass = number of moles * molar mass
Molar mass of oxygen gas = 32.0 g/mol
Mass of 2 moles of oxygen gas = 2 * 32.0 = 56 g
Therefore, the mass of oxygen required in grams is 64
They are a great way to beat the summer heat, with much milder temperatures at higher elevations bc there is fresh air, and studies have shown that living in higher elevations can have positive health benefits, such as improved cardiovascular health, weight loss, and longevity of life.
Answer:
Non-coding DNA.
Explanation:
Inversion is a type of chromosomal abnormality in which the sequence of a segment of a chromosome is inverted or rotated at an angle of 180 degrees. This type of abnormality can change the reading frame of the gene and can cause mutations.
But if the genome sequence is non-coding that is not involved in the formation of protein synthesis than even if the reading frame is inverted will not affect the phenotype of the cell. Also, the non-coding sequences are removed by the splicing mechanisms.
Thus, Non-coding DNA is correct.
Answer:
This is an example of founder effect.
Explanation:
Founder effect may be illustrated as the loss of genetic variation in a novel small population originated from the original population. The concept was initially presented by Ernst Mayr. It can be seen that genetic diversity has got reduced in the population of iguana due to the result of the flood that has washed all the iguana without webbed feet into the sea.
The new population has got inclined from the small iguana population. Thus, the iguana population is regarded as an illustration of the founder effect.
