American apple cells contain an enzyme that turns the tissues brown when an apple is peeled and left for a time. Boiled apple does not go brown. Explain why the boiled apple behaves differently.
Answer:
I think I got it from recipetips.com
When cooking apples it is not as much of a concern because once they are cooked, the browning will stop. When fresh apples are peeled or cut open, the apple's cells are exposed and react with the oxygen in the air. The reaction that occurs, which is called oxidation, is what turns the apple brown.
Explanation:
Enzymes are proteins. As such they are very specific. When the apple is boiled, the enzyme becomes denatured and as such doesn't turn the apple brown.

during which stage of meiosis does the diploid parent cell become four separate haploid cells?
Answer:
To summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.

the tensor fascia latae is involved in hip __________.
Answer:
Abductor Muscle.
Explanation:
The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

Collagen has: Group of answer choices pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable). rings of glycine, which can stabilize helices and proline residues at every third position (because only proline residues can fit inside of the super-helical cable). rings of proline and glycine residues at every second position. pyrrolidine rings, which can push off and destabilize the helix and glycine residues at every second position (because only glycine residues can fit inside of the super-helical cable).
Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).
Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.
Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.
Hence, collagen typically makes up about 30% of the proteins contained within the human body.
Additionally, collagen comprises the following specific amino-acids:
Hydroxyproline.Glycine.Arginine.Proline.Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.
Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

usain bolt, a world champion sprinter, can run a 10-meter split in 0.82 seconds. say you obtain a quadriceps muscle sample from usain bolt and compare it to one from a 25-year-old male long-distance runner. what differences do you expect to observe between those two muscle samples? select all that apply.
A quadriceps muscle sample from Usain Bolt and compared it to one from a 25-year-old male long-distance runner, and it is seen that there are more fast-twitch fibers and red and white muscle fibers of larger cross-sectional area in Usain Bolt's leg muscles.
What is the distinction between fast-twitch and slow-twitch muscles?Athletes who run fast, such as sprinters, have more fast-twitch muscle, which is called "white muscle," as they need more energy for a short period of time, and as a result, the muscles anaerobically respire. The slow twitch muscle, called "red muscle," is more commonly seen in the long distance runner, such as in the marathon, and these runners need a continuous supply of energy for a long time, so aerobically the muscle respires.
Hence, a quadriceps muscle sample from Usain Bolt was compared to one from a 25-year-old male long-distance runner, and it was seen that there are more fast-twitch muscle fibers and red and white muscle fibers with a larger cross-sectional area in Usain Bolt's leg muscles.

What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.
