AP Science Practice Question
A particular enzyme has an optimal temperature of 37°C and begins to denature at 45°C. During
denaturation, entropy increases (the protein loses much of its organization). The protein also
increases its energy content (energy must be absorbed from the surroundings to break the
numerous weak bonds that reinforce the native conformation). Thus, for denaturation, AS and
AH are both positive. Using the free-energy equation (AG = AH - TAS), explain why
denaturation becomes spontaneous at a certain temperature.

Answers

Answer 1

Denaturation becomes spontaneous at a particular temperature when TΔS >  ΔH therefore ΔG becomes negative.

An enzyme is a biological catalyst that promotes various reactions in the body. Enzymes are proteins. There is an optimum temperature within which proteins functions effectively. Beyond this limit, the ability of the protein to function effectively is greatly hampered.

The free energy equation is ΔG =  ΔH - TΔS. Since the energy absorbed increases, the entropy increases and the temperature increases, it follows that a point comes when TΔS >  ΔH therefore ΔG becomes negative and denaturation becomes spontaneous at a certain temperature.

Describe the behavior of the chromosomes in then second division of meiosis.​

Answers

Answer:

The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine, and then separate at anaphase I. At anaphase II, sister chromatids separate. However, studies of small chromosomes in maize derived from a variety of sources typically have failure of sister chromatid cohesion at anaphase I. This failure occurs whether there is pairing of two copies of a minichromosome or not. These characteristics have implications for managing the transmission of the first generation artificial chromosomes in plants. Procedures to address these issues of minichromosomes are discussed.

Normal chromosomes enter into meiosis following DNA replication. The homologous pairs find each other in the process of synapsis. Recombination exchanges parts of the homologs involving two of the four chromatids present. Then in anaphase I, each member of the pair segregates to opposite poles and into the two cells resulting from meiosis I. In contrast to mitosis, the sister chromatids of each homolog remain attached to each other. At meiosis II the sisters now separate to opposite poles. The consequence of this sequence of events is that segregation of genetic markers on the two members of the pairs of homologs enter into different gametes that will eventually be formed after meiosis. However, small chromosomes as observed in maize do not follow these rules. In this review, we describe the information known about these minichromosomes and what they inform us about meiotic processes. Also, the behavior of small chromosomes impacts how engineered minichromosomes will behave and so information about them is important for practical applications as well.

A recent diet trend has made snack cakes far less popular than they once were. As such, demand for snack cakes is expected to
fall. As demand falls, (1 point)
o producers make lower profits, and some will exit the market
O consumers face lower prices, and are encouraged to consume more
O consumers face higher prices, and are encouraged to consume less
O producers make higher profits, and more will enter the market

Answers

The answer is: A - producers make lower profits, and some will exit the market.

Explanation:

When you aren’t making money from a product you’re selling, you’re not going to want to sell it anymore. Instead you’re going to want to sell what the market has more of a demand for.

I hope this was right :)

Producers make lower profits, and some will exit the market. The correct option is A.

Thus, Reduced demand for snack cakes will probably result in decreased profitability for producers, and some may even decide to leave the market.

This decline in demand could affect the profitability of snack cake producers by resulting in lower sales and revenues.

In addition, prices may drop as a result of the decline in demand to entice customers to purchase more of the falling snack cakes.

Thus, Producers make lower profits, and some will exit the market. The correct option is A.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
a scientific theory? Do you think it should be a scientific law? Explain your response.


Answers

Explanation:

OK, first of all, let me explain to you, what is a scientific theory...

A scientific theory is an explanation and demonstration of an aspect that exists in the natural world or universe that has been verified by the scientific way through repeated testing of the experiment with accepted protocols of observation, measurements and evaluation of results.

A scientific law is generated in the same procedure as above, but it can predict a wide range of natural phenomena.

Ex-: you are throwing a basketball from the top of a dam to the river. according to physics on earth, it should fall down. it's a law. no matter where you are, that basketball touches down the ground if there's any gravitational force.

But cell theory cannot be assumed to be common throughout the entire universe. Because we may find some other form of life that has some other plans. viruses are not obeying this theory.

*In a nutshell, a law is stable from its' origin. most of the time, it won't change. but theories will change with updating facts of science.

Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.

Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.

Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.

- If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be?

Answers

Answer:

If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.

Explanation:

If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

What is a Hypertonic solution?

A hypertonic solution may be defined as a type of solution that significantly has lower osmotic pressure than another solution to which it is compared. If the surrounding solution has a higher solute concentration compared to inside the cell, it represents a hypertonic solution.

According to the context of this question, if a 0.9 % salt solution is isotonic to an animal cell, then anything greater than 0.9% would be hypertonic. So, all the options except for 1.0% are lesser than or equal to 0.9%.

Therefore, if a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.
