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.

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.

What is the use of insulin in the body?
Answer:
The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy. Store excess glucose for energy. After you eat — when insulin levels are high — excess glucose is stored in the liver in the form of glycogen.
Explanation:
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.

What do you mean by cuticle?The cuticle is a layer of clear skin located along the bottom edge of your finger or toe. This area is known as the nail bed. The cuticle function is to protect new nails from bacteria when they grow out from the nail root.
A cuticle is a hydrophobic boundary layer on the outer surface of primary aerial organs. Its presence is a common feature of all vascular and some non-vascular plants.
The cuticle plays an important role in nail health. They provide protection for the tissue that grows new cells to build nails. As you know, your nails are constantly growing, that's why you have to keep them manicured.

When liquid turns into vapor
Explanation:
hope this helps <33
have a nice day
mark as brainliest plz? :)
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Temperature, surface area, wind speed, and humidity affect a liquid's evaporation rate.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

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.
