Part A: Explain how Enzyme A acts as a catalyst in the reaction Be sure to include energy and time in your response.






Part B: Conditions around an enzyme change and affect the shape of the enzyme’s active site. Predict how this would affect the enzyme’s ability to catalyze (speed-up) the reaction.

Answers

Answer:

A) Enzymes and chemical catalysts both affect the rate but not the equilibrium constant of a chemical reaction. Reactions proceed downhill energetically, in accord with the Second Law of Thermodynamics. Catalysts merely reduce the time that a thermodynamically favored reaction requires to reach equilibrium. Remember that the Second Law of Thermodynamics tells whether a reaction can occur but not how fast it occurs.

. Compare: Compare the human and animal samples (human and mouse skin; human and worm neurons; human and fly muscle; human and frog blood). A. In general, are there any major differences that you can see? Explain.

Answers

Answer:

The epidermis which is the outermost layer of the skin vary when comparison is made between a human and animal skin.

Human skin has a thicker epidermis while Animals have a thinner epidermis.

The difference between human and insect muscles is that insect have mainly striated muscles which are primarily made of sarcomeres while animals have both the smooth and striated muscles.

The blood is different in humans and frog as humans red blood cells don’t have a nucleus while that of frogs have a nucleus in the red blood cells.

Human beings have very specific differences from other animals, due to their physical and biological constitution.

Based on this, we can answer the above question as follows:

Human skin and mouse skin are different in that human skin has seven layers, while mouse skin has between 10 to 20 layers.A worm has 302 neurons, while a human being has about 86 billion neurons.The fly has muscles adapted to flight, which allows these muscles to be rigid, resistant, and striated. On the other hand, human muscles are less rigid, are not adapted to flight, and can be smooth or striated.Human blood goes through a double circulation type and is of the complete type, while the frog's circulation is of the incomplete type, as it allows the mixture rich in oxygen with the blood rich in carbon dioxide.

Erik remembered that his
science teacher had told him that an explosion in space could not really be heard. Why
is this so?

Answers

Because space is a vacuum, gases released into space expand very quickly, and as they expand their density decreases.

a. The rotational period matches the orbital period

b. it rotates perfectly allowing us to see all sides

c. the moon is locked in its orbit and cannot get any closer or further from us

d. the moon never rises or sets in the sky​

Answers

Answer: A. The rotational period matches the orbital period.

Explanation: Tidal locking results in the moon rotating about its axis in the same time it takes to orbit Earth. So the moon is tidally locked in to the Earth ,because  it takes the exact same amount of time as it takes to orbit the Earth Which is why we only see one side of the moon.

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then drew hemolymph samples from the mussels. The results are presented below. Is the researchers' hypothesis supported by the data? Explain.

Answers

The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.

Answer: YES, SUPPORTED

Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.

These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.

In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).

Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide.
