Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth
Answer:
The correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Explanation:
As they added sweet grape juice mixture the amount of sugar increased in the content and it is seen that more than 6 % of sugar decreases the rate of fermentation and alcohol concentration also decreases and a moderate amount of glucose concentration in the anaerobic environment increases the fermentation results in more alcohol production.
High sugar concentration decreases fermentation but increases cellular respiration in the yeast, as a result, it uses more sugar for its growth and produce CO₂ and H₂O so alcohol is not the by-product of cellular respiration. Therefore the correct answer is d. high sugar concentrations stimulate cellular respiration, and alcohol is not a by-product of cellular respiration.
Answer:
The missing of Taq DNA polymerase will affect the DNA synthesis or polymerization step.
Explanation:
Taq DNA polymerase is also known as termostable DNA polymerase because it is able to exert its catalytic activity at high temperature.
Taq DNA polymerase is used for the 3rd step of polymerase chain reaction which deals with the joining of nucleotides by phosphodiester bond formation.
The missing or lack of Taq DNA polymerase will affect the DNA synthesis step of PCR.
Answer:
When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.
Answer:
C. Some marsupial mole rats had a natural immunity to the virus.
Explanation:
According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation
