The cells formed at the end of the process contain the same number of chromosomes as the original cells.
The statements is true of the process shown below is that the cells formed at the end of the process only have half of the chromosomes as the original cells. Thus, option A is correct.
Where the formation of cell takes place?The cells formed at the end of the process are identical to the original cells. The cells formed at the end of the process do not contain any of the genetic material from the original cells. When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.
Option two of the question states that the cell cycle will proceed uncontrollably, this is not the case for the error at hand. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment.
The stop or delay in the cell cycle is what normally takes place in these situations. This stoppage is done by the spindle checkpoint, which prevents duplicate chromosomes from separating.
Therefore, The statements is true of the process shown below is that the cells formed at the end of the process only have half of the chromosomes as the original cells. Thus, option A is correct.

15 index ofreaction 21820 and the angle of medence is as degres what's the angle of reaction
16 degrees
32 degrees
48 degrees
64 degrees
Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
The angle of refraction is 32.0 degrees
Refractive index and Shell's lawSnell’s Law describes how a ray of light will change direction as it passes from one medium into another, or as it is reflected from the interface between two media.
Snell's law states that:
n1 * Sinθi = n2 * Sinθrwhere;
nA is refractive index of media Aθi is the angel of incidence in media 1n2 is the refractive index of media 2θr is the angle of refraction in media 2Using the formula above
1.5 * sin 45 = 2.0 * sin r
sinr = 1.5 × sin 45/2
r = 32.0 degrees
Therefore, the angle of refraction is 32.0 degrees

Describe the general structure of the monomers
Answer:
The monomer is an amino acid, and I will describe it below. :)
Explanation:
Rubisco is an enzyme found in plants, and its job is to fix carbon. Since we know it is an enzyme, we also know it is a protein since pretty much all enzymes are proteins. The monomer of proteins is the amino acid.
The structure of an amino acid looks like this (see the picture). On one side we have a basic amino group, on the other side we have an acidic carboxyl group. The combination of the amino group and acid group gives us the name amino acid. Also notice that there is the R group. Each amino acid has the same basic structure (with the amino group and carboxyl group), but the unique R group is what gives the particular amino acid its unique characteristics. There are about 20 different kinds of R groups which is why there are 20 different types of amino acids.
So, having a non-polar R group would allow it to interact with a hydrophobic amino acid in another Rubisco molecule.
Monomers are the basic unit of polymers. They are composed of carbon, oxygen, and hydrogen atoms, joint by covalent bonds. There are different monomers which vary in structure, such as nucleotides and amino acids.
-------------------------------------------------------------------
Monomers are the basic unit of polymers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer.
There are many types of monomeric molecules. To name a few, we can mention
Monomer Polymer
Monosaccharide ⇒ CarbohydratesFatty acid ⇒ LipidsAmino acid ⇒ ProteinsNucleotide ⇒ Nucleic acids
Monomers are organic molecules of reduced molecular mass. They are basic units relatively simple, with a defined structure.
Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.
For instance,
Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.Amino acids are monomers composed of a central carbon, one hydrogen atom, one carboxyl group, one amine group, and one R group. The composition of the R group is what makes them different from each other.Every monomer has a free H atom and a hydroxyl group (-OH) in the extremes. When two monomers get together, the H atom and the -OH join to form a water molecule, which is released. The result is a polymer of two monomers and H₂O.

Researchers are studying lichens growing on trees in a forest ecosystem. At the beginning of the study, the researchers identified twelve lichen species in the forest. Later, a forest fire happened in the study area. The researchers returned to the area and found only six lichen species. What inference is best supported from the researchers observations?
Answer:
Certain lichen species are better adapted to survive forest fires than others.
We can conclude that Initial area of the forest was suitable for lichens whereas the later area was not suitable for lichens.
What are lichens?Lichens do not have vascular tissue like xylem and phloem to carry nutrients and water throughout their thalli like a plant does, nor do they have a waxy coating like plants do on their leaves.
The structure of the lichen incorporates everything in its surroundings. Lichens obtain their water and nutrients from the air and rain that fall on them. A lichen's basic structure is made up of layers of fungus and algae.
If there is already a green algal layer present, cyanobacteria can be found in a layer beneath the upper cortex or in microscopic pockets on top of the upper cortex. The lichen will be dark green, brown, or black in color thanks to cyanobacteria.
Therefore, We can conclude that Initial area of the forest was suitable for lichens whereas the later area was not suitable for lichens.

The situation that most likely involves the hormone gibberellin is A. The development of new seedlings.
Gibberellins are plant hormones that stimulate several processes, including shoot elongation, seed germination, and fruit and flower maturation. Specifically, gibberellins break dormancy in seeds, which is typically a state of inhibited growth and development.
These hormones do so by activating the transcription of genes encoding for enzymes like amylase which break down stored starches in the seed into simpler sugars necessary for the growth of the seedling. Moreover, gibberellins promote the cell elongation of young roots during the germination process.
When water is available, it activates gibberellins, leading to seed germination; conversely, the absence of water leads to increased abscisic acid which inhibits gibberellins and thus prevents germination.
