There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer.
More hydrogen peroxide will be broken down in the summer…show more content…
Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.
Sulfuric acid - was used to stop the reaction with catalase and hydrogen peroxide. It denatured the enzyme (catalase) and halted the reaction so the amount of hydrogen peroxide decomposed could be measured.
Before performing part D of the experiment, why was it necessary to establish a baseline?
The baseline is a control and shows the amount of decomposed hydrogen peroxide in the initial sample.
You may have observed the reaction of naturally occurring catalase in tissue from either liver or potato. Design an experiment to determine if the amount of catalase varies from tissue to tissue (e.g. 200 g of the liver compared to 200 g of potato).
Put the 100 g of potato in 1 petri dish and 100 g of the liver in another petri dish. Then put equal amounts of hydrogen peroxide for an equal period of time in both dishes. Drain the dishes and titrate them with potassium permanganate simultaneously. The numbers can now be compared using the steps in the sample calculation above in the lab report. In order to compare perform a potassium permanganate titration on pure hydrogen peroxide.
Of the thousands of enzymes known, there is a family of enzymes called proteases that catalyze a reaction of breaking down proteins. What do you think would happen if you added a protease to your sample of catalase before proceeding with your experiment?

Explanation:
Mercury has greater cohesion than adhesion.
What is adhesion?The attraction between two distinct phases is known as adhesion. Adhesion cannot be explained by a single theory, however it is frequently split into two categories: mechanical interlocking and physical and chemical bonding. Adhesion often results from a mixture of the several mechanisms described below.
When two dissimilar phases only attach to one another mechanically, mechanical interlocking occurs. Typically, for the other material to penetrate, the surface needs to be a little bit rough. adhesion processes
For instance, a low viscosity glue that easily penetrates surface pores and fissures. After the adhesive has dried, this causes mechanical anchoring between the two components.

How did the drought lead to an increase in beak size in the medium ground finch population? the grants reasoned that
The drought resulted in an increase in beak size in the medium ground finch population because the birds with larger beaks were better adapted to consume the larger seeds during times of drought, while the birds with smaller beaks were not as efficient and died out.
During the drought on the Galapagos Island, the finches with larger beaks survived more than the ones with smaller beaks, resulting in a remarkable change in the finch population.
The Grants reasoned that the increased beak size is due to the adaptation of the birds to a drier environment.
In the Galapagos Islands, which are characterized by harsh environmental conditions, Charles Darwin was able to document the phenomenon of natural selection and evolution. The finches on the Galapagos Islands, in particular, have been studied by numerous researchers, including the Grants, who have studied the medium ground finch population.
The Grants found that droughts had a significant effect on beak size in this species. In times of drought, the availability of smaller seeds declines, resulting in a greater availability of larger seeds. The medium ground finches with larger beaks were able to consume the larger seeds more efficiently, allowing them to survive better in the drought conditions.
Thus, due to the shortage of food, the larger-beaked birds survived while the smaller-beaked birds died out.
As a result of natural selection, the beak size of the medium ground finch population increased over time, allowing it to better adapt to its environment.
Therefore, it can be concluded that drought led to an increase in beak size in the medium ground finch population, and the grants reasoned that this was due to the adaptation of the birds to a drier environment.
Answer: In conclusion, the drought resulted in an increase in beak size in the medium ground finch population because the birds with larger beaks were better adapted to consume the larger seeds during times of drought, while the birds with smaller beaks were not as efficient and died out.

which kind of vessel provides a bypass for a capillary bed?
Arterioles are the type of vessel that provides a bypass for a capillary bed. Arterioles are small arteries that can constrict or dilate to regulate blood flow.
When blood flow needs to be diverted away from a capillary bed, arterioles can constrict and direct blood to another area of the body.he metarterioles can serve either as thoroughfare channels to the venules, which bypass the capillary bed, or as conduits to supply the capillary bed. There are often cross-connections between the arterioles and venules as well as in the capillary network.The microcirculation is comprised of arterioles, capillaries, and venules. Arterioles range from 10 to 150 μm in diameter and regulate the distribution of blood flow to capillaries (0.5–1 μm). Small arterioles (metarterioles) can bypass the capillary beds, shunting flow directly into the small venules (10–40 μm).A capillary bed can consist of two types of vessels: true capillaries, which branch mainly from arterioles and provide exchange between cells and the circulation, and vascular shunts, short vessels that directly connect arterioles and venules at opposite ends of the bed, allowing for bypass.

how do i stop a flood or prevent one from happening like an invention
Measures might include using small barriers in ditches and fields, or notches cut into embankments, to divert the water into open land. Letting pools form outside the main channel of a river means the water is temporarily removed from the main flow - reducing the power of the floodwaters
what drives the flow of water to move from the ocean to the atmosphere?? is it
a. earth's gravity driving the flow of liquid water
b. heat energy
c. light energy
d. matter flowing into the ocean
e. earth's gravity driving the flow of matter and energy
Answer:
b. heat energy
Explanation:
Water, which is able to exist in three different states moves from one form to another. Water can move from the ocean to the atmosphere via a process called EVAPORATION. During the process of evaporation, the sun plays a major role by supplying the HEAT ENERGY required to change water from its liquid form in the ocean to its gaseous form in the atmosphere.
Water cycle of the earth helps ensure that water is not lost in any of its forms. Liquid water stored in the ocean gets evaporated as a result of heat energy into the atmosphere as water vapour.

let (gen,h) be a collision-resistant hash function. is (gen, h ) defined by hs(x) ≝ hs(hs(x)) necessarily collision resistant? justify your answer, show all the steps necessary.
Yes, if (gen, h) is a collision-resistant hash function, then (gen, hs) defined by hs(x) ≝ h(h(x)) is also necessarily collision-resistant.
Determining as collision-resistantTo justify this, consider the following:
1. Assume that hs(x) is not collision-resistant, which means there exist distinct values x1 and x2 such that hs(x1) = hs(x2).
2. Based on the definition of hs, we can rewrite the equation as h(h(x1)) = h(h(x2)).
3. If h is collision-resistant, then it's infeasible to find x1 ≠ x2 such that h(x1) = h(x2).
Since we have h(h(x1)) = h(h(x2)), the only way for this equality to hold is if h(x1) = h(x2).
4. However, this contradicts our assumption that h is collision-resistant because we assumed x1 ≠ x2.
Therefore, hs(x) must be collision-resistant as well.
So, if (gen, h) is a collision-resistant hash function, then (gen, hs) defined by hs(x) ≝ h(h(x)) is also necessarily collision-resistant.

How do you find the sequence of bases on a DNA strand?
Answer:
First of all, make sure that you indicate on the question itself the directionality of the sequence: which makes this (by convention) 5′ AGCTCAG 3′. We assume that any sequence written without the 5′ and 3′ designations is from the sense strand, and reads from 5′ on the left to 3′ on the right. Therefore, the complementary sequence, which is being asked for, must go from 3′ to 5′ as matched up (because it runs in the opposite direction). So, this is 3′ TCGAGTC 5′. It is true that we often write sequences without the formal directionality indicators, and if so, we do it from 5′ to 3′. However, if you put “CTGAGCT” as your answer, experience tells me that you have a very good chance of getting it marked wrong (unless your instructor is testing you all with a little tricky questioning).
