The structure of DNA is called a "double helix" which is simply a twisted ladder. Or, twisted staircase.
DNA is made up of a double helix. To put it another way, it is a spiral-shaped, double-stranded molecule. Deoxyribose sugars alternate with phosphates to create the molecule's exterior, or the rails of the stairway. The "backbone" of the molecule is another name for this area.The double helix, which resembles a twisted ladder, is the shape of DNA. Sugar and phosphate molecules alternately make up the sides of the ladder. It is deoxyribose, the sugar. The ladder's rungs are made up of pairings of the four different nitrogen bases.A lengthy polymer is created when the phosphates and sugars of nearby nucleotides connect. They demonstrated how the twisted uprights of the DNA ladder are made up of alternating deoxyribose and phosphate molecules. The complementary pairings of nitrogen bases that make up the ladder's rungs are A always paired with T and G always paired with C.DNA Replication Deoxyribonucleic acid, also known as DNA, resembles a long, spiralling ladder. It only has carbon, hydrogen, oxygen, nitrogen, and phosphorus as its main atom types. The sides of the DNA ladder, or the sugar-phosphate backbone, are made up of combinations of these atoms.To know more about double helix check the below link:

which statement is true?a. a virion contains dna and rnab. viruses are acellular c. viruses replicate outside of the cell d. most viruses are visualized with a light microscopee. none of the above
Viruses are acellular organism, they are exception to cell theory.
A virus is an infectious microbe made up of a protein-coated segment of nucleic acid (either DNA or RNA). A virus can't replicate by itself; it needs to infect cells in order to use the host cell's components to make copies of itself.
For instance, COVID-19, Ebola, and HIV are all viruses, as are the common cold and the flu. Even minor viral infections in healthy people can become quite serious for those with compromised immune systems.
Viruses "hijack" your body's healthy, living cells. You get sick because they utilize these cells as a means of reproduction and growth before ultimately destroying the host cell.
Hence, virus are non cellular particles need living system to reproduce.

Jason put an apple on top of an ice pack in his lunch bag. By lunchtime the temperature of his apple had decreased. What happened to the molecules in the apple when the temperature of the apple decreased?.
When the temperature of the apple decreased, the thermal energy molecules in the apple are reduced.
Thermal energy is energy produced when there is an increase in temperature. Due to the increase in temperature, the molecules and atoms will move faster. Heat energy arises from the movement of particles. Thermal energy can be sourced from solar thermal energy, geothermal energy, fire heat energy, electrical heat energy, and heat energy from abrasions of two objects. The nature of thermal energy is that it can move from objects with a higher temperature to objects with a lower temperature.
Apples have warm energy along with the molecules that are in the apples. When the apples are placed on the ice bag which has a lower temperature than the apples. Then the energy of the apple molecules will transfer to the ice bag through kinetic energy.

TRUE/FALSE. the inflammatory process involves a cascade of events that results in dilation of blood vessels, leakage of fluid from those vessels, and migration of leukocytes out of the bloodstream and into the tissues.
The inflammatory process involves a cascade of events that results in the dilation of blood vessels, leakage of fluid from those vessels, and migration of leukocytes out of the bloodstream and into the tissues is true.
When tissues are damaged by an infection, trauma, toxin, heat, or any other cause, the inflammatory response, also known as inflammation, takes place. Chemicals like histamine, bradykinin, and prostaglandins are released by injured cells. These medications result in edema by causing blood vessels to leak fluid into tissues.
To reach sites of infection, injury, and stress inside the interstitium, neutrophils, monocytes, and effector T lymphocytes must pass through active venular walls.
Due to their inability to swim, leukocytes must be transported locally to the site of inflammation via a variety of adhesive procedures that enable them to stick to the vessel wall and travel along it to the endothelial boundaries.

If a purple-flowered, heterozygous plant were crossed with a white-flowered plant, what is the expected ratio of genotypes among the f1 offspring? suppose p is a dominant allele for a flower color and p is a recessive one.
suppose P is a dominant allele for a flower color and p is a recessive one.
The expected ratio of genotypes among the F1 offspring is 1 Pp : 1 pp.
The white pea bloom was "masked" in the F1 generation, which caused all of the flowers to be purple.
The "masked" genes from the F1 generation were permitted to mate, but they were only allowed to pair once, leaving the other three times to appear with purple flowers, resulting in a 3:1 ratio of purple to white blooms in generation F2.
He paired a homozygous dominant flower with a homozygous recessive flower in his initial attempt. As a result, all of the F1 generation's progeny were heterozygous, making them all purple.
Two heterozygous, one homozygous recessive, one homozygous dominant, and the progeny of the F1 generation were crossed with another heterozygous plant.
