Answer:
Recombinant DNA is technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory. Then they remove a loop of bacterial DNA known as a plasmid and insert the human insulin gene into the plasmid. Researchers return the plasmid to the bacteria and put the “recombinant” bacteria in large fermentation tanks. There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria and purify the substance for use as a medicine for people.

achondroplastic dwarfism involves a spontaneous genetic mutation resulting in chondrocytes that fail to multiply and enlarge at epiphyseal plates. considering this information, why do flat bones develop normally in a person with achondroplasia?
In achondroplasia, the frame has trouble turning cartilage into bone, particularly in the long bones of the arms and legs. This outcome in shortened bones, brief stature, and other different physical characteristics.
In achondroplasia, this protein starts offevolved to characteristic abnormally, slowing down the growth of bone inside the cartilage of the growth plate. This leads to shorter bones, abnormally-shaped bones, and shorter stature; a person top in human beings with achondroplasia is between 42 and 56 inches.
Dwarfism (skeletal dysplasia) impacts bone growth in your body. The most common bones that dwarfism influences are the long bones inside the arms and legs, however, it is able to have an effect on different bones together with the bones to your legs and arms as well as your stomach and head.
Achondroplasia is a bone increase sickness that causes disproportionate dwarfism. Dwarfism is defined as a situation of quick stature as a person. people with achondroplasia are brief in stature with a normal-sized torso and brief limbs. it's the most common form of disproportionate dwarfism.

If you sum all the fractions of atoms, how many atoms are actually inside a simple cubic unit cell?
If we take the sum of all the fractions of atoms, then 1 atom is present inside a simple cubic unit cell.
In a simple cubic unit cell, there is only one atom located at the corners of the cube. When we take the sum all the fractions of atoms, we consider that each corner atom contributes 1/8th of an atom to the unit cell since it is shared among eight adjacent unit cells.
Therefore, if we add up the fractions,
we get 1/8th + 1/8th + 1/8th + 1/8th + 1/8th + 1/8th + 1/8th + 1/8th = 1 atom.

10. In a few sentences, summarize how
a gun works from the point it is loaded
to the point that the bullet is fired.
A gun works by using the energy generated by the combustion of gunpowder to propel a bullet out of the barrel and toward the target.
Here is the process in more detail:
Loading: The gun is loaded by inserting ammunition into the magazine, which is typically located in the handle of the gun. Some guns may also be loaded one round at a time, directly into the chamber.Chambering: Once the gun is loaded, the first round is moved from the magazine into the chamber, which is part of the barrel where the bullet is positioned.Cocking: The gun is then cocked, which involves pulling back the hammer or striker to create tension in the firing mechanism.Aiming: The shooter aims the gun at the target by lining up the sights on the gun with the target.Firing: The shooter pulls the trigger, which releases the hammer or striker, causing it to strike the primer on the round in the chamber. The primer ignites the gunpowder in the round, creating a high-pressure explosion that pushes the bullet out of the chamber and down the barrel toward the target.Ejection: After the bullet has been fired, the spent casing is ejected from the chamber and the next round is automatically moved into the chamber, ready to be fired again.Know more about guns here: brainly.com/question/10955354

Some. produces variable traits depending on environmental conditions
Answer:
Some genes produces variable traits depending on environmental conditions
Explanation:
The interaction between some genes and environments confers on individuals different degrees of susceptibility in the appearance of a certain characteristic or in the expression of some variable traits. The trait appears in individuals who have reached a certain threshold, thus the variability in phenotypic expression could be related to the greater or lesser number of predisposing genes in each individual. The differential expression of genes depending on the environment is called the reaction norm, and it refers to genes that can be expressed in a different way in different individuals, depending on the environment in which those individuals develop. The norm of reaction is the set of pathways that a genotype can follow, in all favorable and unfavorable environments, until giving rise to the various possible phenotypes.
