In 1952, Rosalind Franklin produced an image of DNA that suggested it contained two strands twisted in a double helix with a phosphate backbone and bases inside. Franklin calculated the diameter of DNA, the distance between strands and bases, the angle of the helix, and the number of bases per coil.

Watson and Crick used this information to build and accurate model of DNA.

Rosalind Franklin was the one who pioneered the structure of DNA through his X-ray diffraction images at King's College. His failure to explain the double helix structure was the reason why Watson and Crick were the person who were accounted by the discovery. The huge model by Cirick and Watson proved the theory of Franklin who failed to give an evidence.

4. Ocean currents and waves sometimes deposit sand and dirt offshore, building up a new landform called a(n) Barrier island. Est
lions [1.4K]

Answer:

Barrier island

Explanation:

Barrier islands represent a class of coastal landform composed of sand and sediments that forms parallel to the coast. These islands are constantly changing, being shaped by different factors which include water currents (ocean currents), erosion and waves. Some of the most important parameters that influence the length and width of barriers are tidal range (i.e., the height difference between high tide and low tide), wave energy (i.e., the energy restrained from oceanic waves), the amount of sediment supply and sea-level trends.

Each of the following will enhance and promote phagocytosis, except Multiple Choice tumor necrosis factor (TNF) and other cytoki
ozzi

Answer:

The correct answer is: deposition of interferon on bacterial cells.

Explanation:

Phagocytosis is the mechanism by which a cell uses its plasma membrane to ingest a big particle, forming a phagosome within the cell. It's a form of endocytosis used by the <u>immune system to eliminate pathogens such as </u><u>bacteria </u><u>and cell debris</u>.

Phagocytosis can be enhanced through various ways when an infection is taking place in the body. For example, cytokines and TNF are secreted by different kinds of cells to stimulate this process - for these cytokines to be released, certain parts of the bacteria called PAMPs need to be recognized by specific receptors located in phagocytes and epithelial cells called TLRs. Another way to stimulate this mechanism is by depositing complement fragments on bacterial cells, which is done thanks to the Complement cascade, a system of great importance in the innate immune response against extracellular bacteria - these fragments will opsonize ("mark") the pathogens for the phagocytes to recognize them and engulf them.

Interferon, on the other hand, while hugely important on the immune response against viruses and other pathogens that infect our cells by entering them and using their organelles to replicate and translate proteins, is not an enhancer of phagocytosis, as it is mostly involved in the translation of genes that will lead to the infected cell's death.

White rabbis blend in with the snow. brown rabbits are more likely to be eaten by predators. is the population of rabbits in gen
TiliK225 [7]
Yes, the population of rabbits is in genetic equilibrium because both white and brown rabbits have equal chances of survival throughout the year. During the winter season, the brown rabbits stand out and are likely to be eaten by predators, but during the summer, white rabbits stand out and are likely to be eaten.
