B.

Explanation:

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a △G of -20 kcal/mol. If you double the amount of enzyme in the reaction, what will be the △G for the new reaction?


A. +20 kcal/mol

B. -40 kcal/mol

C. -20 kcal/mol

D. -10 kcal/mol

Answers

Answer:

Option-C

Explanation:

Delta G (△G) refers to the overall energy released during a chemical reaction when equilibrium is reached i.e the rate of conversion of product into the substrate is equal to the rate of conversion of substrate into product. Thus, △G accounts for the equilibrium of the reaction.

In the given question, it has been mentioned that △G of a reaction is -20 kcal/mol then how will it change if the amount of enzyme is doubled.  

The △G is not affected by the enzyme concentration as the presence of enzyme affects the G (Gibbs free energy) and activation energy.

Therefore, △G will remain the same even if the amount of enzyme is doubled i.e -20 kcal/mol will be the correct value.

Thus, Option-C is the correct answer.

Describe the process of water moving in and out of the cell.

Answers

Answer:

Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

1. Describe how the rotation of Earth on its axis affects the tides. Be sure to include the evidence that supports your answer.

Answers

Answer/Explanation:

During low elevated tides, the Earth itself is pulled marginally toward the moon, making elevated tides on the contrary side of the planet. Earths pivot and the gravitational draw of the sun and moon make tides on our planet. As the sea swells toward the moon, an elevated tide is made.

But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

What is the energy source that allows photosynthesis to occur?

Answers

Answer:

[tex]\boxed {\boxed {\sf The \ sun }}[/tex]

Explanation:

Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".

This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.

This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

Is nature or nurture more important

Answers

Answer:

Yes

Explanation:

cus

it keeps us alive

The answer is completely subjective. I’ll assume you are talking about raising children simply because this vocabulary is often used in that case.

Nature can go from describing events out of our control, innate feelings, to describing the area we are raised in. Nature can go a long way with raising kids, in comes the theory’s of the “murder gene.” The aforementioned gene is a theory on the “murderous” behaviors in children sociopaths, or psychopaths. This theory exists because of some unexplainable behaviors the children have that were not taught, like hurting animals and lack of empathy.

In a more lose interpretation of Nature it can mean the area children are raised in. Like the different between a trailer park and a mansion. But generally Nature refers to innate, uncontrollable, behaviors.


On the other hand Nurture refers to the actual raising of the child. Referring back to the “murder gene” the question is if you could reverse the effects of the gene in children based on how you raise them. Nurture is also an argument for how kind you should be to your child as they are growing.

Personally I think Nurture is more important, but in all actuality a good balance is best.

Color blindness is a X-linked recessive trait. A couple want to predict whether it would be possible for their child to be color blind. The female is an unaffected carrier and the male is red/green color blind. What percentage of offspring would be color blind? ​

Answers

Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.

Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.

The male is XY and colour blind, so genotype cY

Male offspring can be cY or CY so p|colourblind = 50%

Female offspring can be Cc or cc so, again p= 50%

If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind

When I came out of my room, I saw Chris heading to the garage with Dad. While Mom was packing some clothes in a backpack, she told me to finish my breakfast quickly. That's when I realized what was happeningwe were supposed to go to the amusement park today. I couldnt wait to go on the Dark Tunnel ride first thing because every guy in my class had already gone on it.The park was a two-hour drive from our home, and it was already crowded when we got there. I headed straight for the Dark Tunnel, but it had the longest line of all. Chris said that we should save it for last, when the crowd would thin out. Try as I might, there was no convincing him otherwise. He was my big brother after all.I almost forgot about the Dark Tunnel because we soon entered the big pool with a machine that created artificial waves. Then there was the Cliffhanger, which Mom didn't allow me to go on, but it was priceless to see Chris's face when he got off the ride. Time was running out on the day, and I was thinking about the Dark Tunnel again. With the park almost closing, we went back to the ride just in time.
