Which phrase describes transmutation?(1 point) the conversion of protons to neutrons through nuclear changes the conversion of one substance to another through chemical changes the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes
Answer:
B
Explanation:
PLEASE MARK AS BRAINLIEST!!!!!Transmutation is conversion of an atom of one element into different element through nuclear changes.
Transmutation consists of the conversion of stable nuclei into other nuclei if they are bombarded by fast particles.
Specifically, an atom can be transmuted by making particles or atoms collide with it at high speed, that is, to accelerate a particle is to increase its speed by some mechanism that imparts energy to it.
Thus, the transmutation of an element requires that there be a change within its nucleus, and in particular in the number of protons.
The neutrons or protons must have enough energy to overcome the nuclear forces that prevent their passage or exit from the nucleus of the atom to be transmuted.
Therefore, we can conclude that transmutation is conversion of an atom of one element into different element through nuclear changes.

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.
If the measures of two angles of a triangle are 91 and 11°, what is the measure of the third angle?
HERR
The measure of the third angle isº. (Simplify your answer.)
Answer:
If I understood your question in the right way, 78°
Explanation:
Cuz, the sum of all 3 internal angles of a triangle is 180°.
180°=91°+11°+x
180°-(91°+11°)=x
78°=x

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.

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.

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)

Answer:
What is B- delivered to the store, prepared and served to the Guest.
Explanation:
The HACCP system begins when the food is delivered to the store and served to the guest.
How HACCP system works?HACCP : hazard analysis critical control point.
It is a management system that addresses food safety through analysis and control of biological, physical and chemical hazard.
There is a working flow of HACCP that ensures food safety begins from raw material production, procurement, handling, to manufacturing, distribution and consumption of the finished food product.
Hence, it can be said that HACCP system begins when food is delivered to the store and served to the guest that is consumption of the final product.

true or false? a haploid organism has one pair of homologous chromosomes.
Answer:
False
Explanation:
A haploid has one SET of homologous chromosomes
It is false that a haploid organism has one pair of homologous chromosomes.
What are haploid organisms?When an organism's cells only have one set of chromosomes, the organism is said to be haploid.
All organisms that reproduce are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.
Male ants, bees, and wasps are haploid organisms because they develop from unfertilized haploid eggs, whereas females (workers and queens) are diploid, making their system haplodiploid. The majority of animals are diploid.
The term "diploid" describes how many complete sets of chromosomes there are in each cell of an organism: diploid cells have two entire sets.
On the other hand, haploid organisms only have one complete set of chromosomes. Throughout meiosis and sporadically in mitosis, chromosome sets can change.
Thus, the given statement is false.

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.
