what are restriction fragment length polymorphisms?
Answer:
difference in homologous DNA sequences
Explanation:
Restriction Fragment Length Polymorphism (RFLP)is a difference in homologous DNA sequences that can be detected by the presence of fragments of different lengths after digestion of the DNA samples in question with specific restriction endonucleases.

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.
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.

according to the induced fit hypothesis of enzyme catalysis, _____.
Answer:
the binding of the substrate changes the shape of the enzyme's active site
Explanation:
According to the induced fit hypothesis of enzyme catalysis, the shape of the active site of an enzyme changes in response to the binding of a substrate molecule.
What is induced fit hypothesis of enzyme catalysis?The active site, which is the region of the enzyme that interacts with the substrate, adjusts its shape to fit the substrate more snugly. This change in shape enhances the formation of the enzyme-substrate complex, leading to more efficient catalysis and faster reaction rates.
The induced fit hypothesis suggests that the active site is not a rigid structure, but rather, is flexible and dynamic, adapting to the substrate to optimize the reaction.

Suppose you remove the rabbits, grasshoppers, birds, and mice ( the herbivores) from a food web that also includes grass, mushrooms, lizards, and hawks. Which organisms would be affected and how?
If you remove the herbivores from a food web that also includes grass, mushrooms, lizards, and hawks, the organisms that would be affect are lizards, and hawks.
A food web shows all the possible feeding relationships in an ecosystem. Recall that there is an interconnection between organisms which involves exchange of matter and energy through feeding relationships.
In the food web, the grass is the producer, the herbivores are the primary consumers and the carnivores are the secondary consumers. These secondary consumers eat the primary consumers.
Lizards eat grasshoppers and hawks eat birds. When these are removed from the food web, the Lizard and Hawk are most affected because they will starve owing to lack of prey.

The descriptions below explain two ways that water is used by plants on a sunny day.
I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.
Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?
A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.
C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.
D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

A plant cell is placed in a salt solution, and the following observation is recorded:
A normal plant cell is on the left. The plant cell wall is visible, and the internal structure fills the cell up to the cell wall. In the middle is an arrow pointing from left to right. On the right is a plant cell. This plant cell has a cell wall the same size as the first plant cell, but the internal structures are shrunken in comparison to the first cell.
Which answer choice describes the most likely concentration of the solution?
Hypertonic
Hypotonic
Isotonic
Osmotic
Answer:
Explanation:
a simple way to look it it is:
Hypertonic would be when the insides are shrunk (arrows point out)
Hypotonic when its full (Arrows point in)
Isotonic is at balance (arrows point out and in)
osmotic: the passage of a liquid through a membrane from a less concentrated solution to a more concentrated one (equal concentrations)

Why does water have a strong surface tension and why is this important?
The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding. ... Formed bonds are called hydrogen bonds which lead to strong cohesive forces between the water molecules and high surface tension of water.
Why is it important?The surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into spherical shapes. Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets.
