Which phrase describes how a range of folded mountains forms?
OA. The movement of two tectonic plates as they slide past each other
B. The movement of magma from the mantle up into the crust
C. The slow, continuous divergence of two tectonic plates
OD. The slow, continuous convergence of two tectonic plates
The movement of two tectonic plates as they slide past each other is the phrase that describes how a range of folded mountains forms.
Fold mountains are created when two or more tectonic plates on Earth are forced to collide, most frequently at locations known as continental collision zones and convergent plate borders. At these interacting, compressing boundaries, rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges.
Fold mountains are the result of a process called orogeny. After millions of years of orogenic action, a fold mountain forms.
In the leading edge of the crust's growth at a compression zone, tectonic activity results in crustal compression. As a result, the bulk of fold mountains is found at or very close to the borders of continental plates.

Answer: The slow, continuous convergence of two tectonic plates
Explanation: I took the quiz and this was the correct answer, but I'll still break it down so you can understand it.
A Folded Mountain Form is "A mountain range formed by the folding of rock due to compression." This means that the correct answer has to be one that includes the tectonic plates colliding with each other. This limits the answer to either C or D.
Divergence is related to Tension instead of Compression, which already makes D a false answer but I'll keep explaining. Convergence is related to Compression instead of Tension, therefore making C the correct answer.

If the water potential of a dialysis bag is -4.0 and the pressure potential was -2.0 and the
solute is sucrose, what was the concentration of the sucrose solution? The temperature
of the room is 37 C. Round to the thousands place (3 decimal places) and don't put the
unit.
The concentration of the sucrose solution is 0.077 moles/L
What is concentration?The amount of a substance, like a salt, that is in a particular amount of tissue or liquid, such as blood. A substance gets more concentrated when less water is present. For example, the salt in urine may become higher in concentration when a person doesn`t drink enough water.
The formula for water potential is Ψ = ΨS + ΨP. The osmotic potential is directly proportional to the solute concentration. As the concentration of a solute in a solution increases, the osmotic potential of water in that solution decreases.
Ψ = ΨS + ΨP
ΨS = Ψ - ΨP
Where, ΨS = Solute potential
ΨP = Pressure potential (-2.0)
Ψ = Water potential (-4.0)
Now, substitute the values:
ΨS = -4.0 - (-2.0)
ΨS = -4.0 + 2.0
ΨS = -2.0
For, solute concentration:
ΨS = -iCRT
ΨS = Solute potential (-2.0)
i = 1
C = Concentration of the sucrose
R = 8.314 × 10⁻² bar L/mol k
T = 37°C or 310.15 K
Now, substitute the values:
-2.0 = 1 × C × 8.314 × 10⁻² × 310.15
C = 0.077 moles/L

A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?
An index fossil will be more useful in dating the rock than ancient relative because carbon dating can be performed using the fossil which will give more accurate details rather than the relative dating performed using ancient relative.
Index fossil is any preserved remains of the plant or animal that is particularly useful for the dating purposes. It is useful for determining the geological periods. Most of the rocks that contain the index fossil are found in marine environment.
Carbon dating is the process of determining the age of ancient objects or fossils. In this the amount of radioactive carbon is measured as the rest forms of carbons stop being absorbed but radioactive carbon continues to decay even after an organism dies.

What is the primary function of the pigment molecules in a light-harvesting complex?.
Light-harvesting complex pigments absorb light and transfer energy to a special pair of chlorophyll a molecules in the reaction centre.
Where are the pigment molecules ?A pigment is a broad term for any molecule that absorbs light and has a distinct colour. Plants contain a variety of pigments, which give rise to the various colours we see. Flowers and fruits are obviously rich in organic molecules that absorb light. Pigments can also be found in the leaves, stems, and roots.
Pigment molecules are frequently organic molecules with "highly conjugated rings" that allow electrons to "bounce" around when "excited." Many other pigments contain transition metals, which transfer electrons between molecules.
Anthocyanins, flavanoids, flavines, quinones, and cytochromes are examples of pigment molecules. None of these, however, should be considered photosynthetic pigments. Photosynthetic pigments are the only pigments that can absorb sunlight energy and transfer it to the photosynthetic apparatus.

Gene thearpy has been used to treat cystic fibrosis. Cystic fibrosis is caused by a ___ in a single gene.
Cystic fibrosis has been treated with gene therapy—a mutation in just one gene results in cystic fibrosis. A parent who carries the CF gene may pass it on to their offspring. After having a kid with CF, parents have a 1 in 4 chance of having another child with the condition.
Cystic fibrosis is brought on by mutations, or mistakes, in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which either prevents the production of any CFTR protein or causes it to be malformed and unable to carry out its essential cellular role. The CF transmembrane conductance regulator (CFTR) gene is mutated, resulting in CF. On 70% of CF chromosomes, a three-nucleotide deletion (delta F508) that results in the lack of a phenylalanine residue in the CFTR gene's tenth exon has been identified.
Thus, we can conclude that a single gene mutation causes cystic fibrosis.

Suppose an individual had a mutation that decreased the enzymatic activity of phosphodiesterase in rod cells. What would be the effect of this mutation on the rod cells?.
The effect of this mutation on the rod cells would be ''A smaller hyperpolarization of the rod would occur''.
How do you explain hyperpolarization ?A cell's membrane potential changes during hyperpolarization to become more negatively charged. It is a depolarization's opposite. By requiring more stimuli to raise the membrane potential to the action potential threshold, it prevents action potentials.K+ (a cation) outflow through K+ channels or Cl- (an anion) inflow through Cl- channels are frequent causes of hyperpolarization. On the other hand, hyperpolarization is inhibited by the inflow of cations, such as Na+ through Na+ channels or Ca2+ through Ca2+ channels. Inhibition of Na+ or Ca2+ currents will also cause hyperpolarization in cells that have those currents at rest.

A catalyst is a substance used to increase the rate of a chemical reaction. Two catalysts are tested to see which will most effectively increase the rate of hydrogen peroxide decomposition. Hydrogen peroxide decomposes into water and oxygen. HYPOTHESIS: Catalyst A will increase the rate of reaction faster than Catalyst B.
what is the independant varible
In the reaction where test is performed to see which catalyst decomposes hydrogen peroxide faster, the independent variable will be both the catalysts.
Catalysts are the chemical that enhance the rate of any chemical reaction. These catalysts work upon reactant or substrate, cause some conformational change and then increase the rate of reaction to many folds. Catalysts themselves do not get changed or reduced in the reaction.
Independent variable in any hypothesis or research is the variable which itself is not affected in the reaction. However, its concentration decides the result of the reaction. Any slight change in independent variable can completely alter the result.

Micelles have been probed as drug delivery carriers for decades. Their use can potentially result in high drug accumulation at the target site through the enhanced permeability and retention effect. Nevertheless, the absence of stability of micelles in the physiological environment limits their effectiveness as a drug carrier.
