Answer:
c. Increasing temperature above the optimal value slows the reaction rate
Explanation:
Enzyme activity is affected by factors, such as temperature, pH, and concentration.
The rate of an enzyme-catalysed reaction increases as the temperature increases. However, increasing the temperature above the optimal value slows the reaction rate because the enzyme becomes denatured and can no longer function.
Thus, the correct option is "C"
c. Increasing temperature above the optimal value slows the reaction rate
Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix
J. The offspring inherits traits from the parents

Answer:
The correct answer is B-typically grow slower than in pure culture
Explanation:
In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.
In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.
So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
