A cell that has just completed anaphase is 22.5 hours old.
What changes occur in the anaphase stage of the cell cycle?The fourth stage of mitosis is known as anaphase.Divides the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells. The sister chromatids, or replicated chromosomes, are positioned along the equatorial plane of the cell before anaphase starts. The sister chromatids are made up of two identical DNA copies linked at the centromere.Each pair of chromosomes divides into two identical, independent chromosomes during anaphase. The mitotic spindle is a structure that separates the chromosomes. A chromosome is attached to one end of the mitotic spindle's many lengthy proteins, known as microtubules, and a cell pole is attached to the other. At their centromeres, the sister chromatids split simultaneously. The spindle subsequently drags the split chromosomes to the cell's opposite poles.To learn more about the anaphase stage of the cell cycle, refer to https://brainly.com/question/13766396?referrer=searchResults

Why were the giant tortoises of the Galapagos Islands considered the better
evidence for evolution for each of the islands in which they were located?
Answer: Galapagos tortoises are actually not of the same species most of them are sub-species of a larger older cousin though they are all classified as the species Galapagos tortoises but are not the same a lot of the sub-species have adapted to be able to live on specified island because not every island in the Galapagos is the same.

An electron present in the innermost orbital shell of an atom if absorbed energy and is kicked out in to
the outer higher-energy shell. What can happen?
Select one:
O a. the electron will come back down to the lower energy shell but will not release any type of energy (heat/light)
Ob. the electron will always remain in the higher energy shell to release radioactivity
Oc. the electron will always remain in the higher energy shell forever to release heat and light energy
Od. the electron will come back down to the lower energy shell and make the atom behave as an isotope
Oe. the electron can come back down to the lower energy shell releasing heat and light energy seen as bioluminescence
Answer: When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
Explanation:
hopes this helps
The electron can come back down to the lower energy shell releasing heat and light energy seen as bioluminescence.
According to the Bohr theory, atoms absorb energy and move from a lower to a higher energy level. The energy absorbed during this transition is equal to the difference in energy between the two levels.
This innermost shell is called the ground state of the atom while the higher energy level is called the excited state. Since atoms are unstable in the excited state, the atom quickly returns to the ground state, emitting energy in the form of heat and light in the process.

Why don't plant cells undergo cytolysis?
Answer:
Cytolysis does not occur under normal conditions in plant cells because plant cells have a strong cell wall that contains the osmotic pressure, or turgor pressure, that would otherwise cause cytolysis to occur.
Explanation:
:)
Answer:
Plants have a natural defense mechanism against cytolysis because they contain a tough cell wall. When a plant cell is placed in a hypotonic environment and water rushes in, the cell wall exerts an opposing pressure on the cell membrane, preventing it from expanding or rupturing. i hope this helps

Polysaccharides, nucleic acids, proteins, and lipids are
that are synthesized from a small collection of basic precursors.
O A
macromolecules
OB.
monomers
Ос
enzymes
Oo
ions
Answer:
Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The interactions between the various components of a cell and its water content is key to biological chemistry.
Sodium, potassium, magnesium, calcium, phosphate, and chloride, are among the chief inorganic ions of a cell, and represent not more than 1% of the cell mass. But the organic molecules are the really novel components of a cell. Most such organic compounds belong to one of the following molecule classes:
Carbohydrates
Lipids
Nucleic acids
Proteins
Within individual cells, there exist thousands of different types of macromolecules, or organic compounds. These will be different, even among the cells of the same person. The variations are more extensive among different people. Macromolecules - proteins, nucleic acids, and polysaccharides - are formed by the polymerization of hundreds of their low-molecular-weight precursors - amino acids, nucleotides, and simple sugars.
The diversity among macromolecules evolves from the vast potential to form different combinations of the 50 or so common monomers which make up a macromolecule. These macromolecules may constitute up to 90% of a cell’s dry weight. It is possible to comprehend the basic chemistry of a cell’s makeup by understanding the functions and structures of the four major types of organic compounds, or macromolecules.
Carbohydrates
Carbohydrates are the basic building materials and nutrients of the body. Simple sugars and polysaccharides compose this group. Glucose is an example of a simple sugar that is an important cellular nutrient. Decomposition of the simple sugars by chemical reaction generates cellular energy as well as initiating the synthesis of other constituents of a cell. The polysaccharides, or complex carbohydrates, represent the form that sugar takes when it is stored. Polysaccharides are the structural components of a cell. Moreover, polysaccharides and other sugars may function as markers for certain cellular recognition processes, including the intracellular movement of proteins.
Lipids
Lipids are hydrophobic molecules. They are a highly efficient form of energy storage, and are major constituents of the cell membrane. They are important in cell signaling, function as the starting point for various biosynthetic processes such as the synthesis of estrogen and testosterone. Some lipids are able to convey signals from cell surface receptors to targets in the same or other cells. Phospholipids contain two fatty acids joined to a polar head group. Besides the phospholipids, cells have glycolipids and cholesterol.
Nucleic acids
Nucleic acids store and transmit hereditary data. DNA and RNA represent the informational molecules of a cell. DNA plays a crucial role as the genetic material of humans and many other species. RNA takes part in various cellular activities. Messenger RNA (mRNA) transports information from DNA to the ribosomes, where they are involved in synthesizing proteins. In addition, ribosomal RNA and transfer RNA are involved in protein synthesis. Other RNA molecules process and move both proteins and RNA. RNA can also catalyze chemical reactions, such as those involving the synthesis of proteins and the processing of RNA.
Proteins
Proteins play an important role in most of the tasks that an organism performs. Proteins carry out the work of a cell, directed by the genetic information carried by the nucleic acids. A cell holds many thousands of proteins, which function as a cell’s structural elements, storing and transporting small molecules, transmitting data among cells, and defending the body against the onset of infections. But proteins also function as enzymes that accelerate most chemical reactions. In this manner, proteins guide most cellular activities.
Explanation:
are the new strands identical to the original segment of DNA?
Answer:
DNA creates "daughters" by using the parental strands of DNA as a template or guide.made in the 5' to 3' direction. Each newly synthesized strand of DNA (daughter strand) is made by the addition of a nucleotide that is complementary to the parent strand of DNA.
