Answer:

Photon radiation

A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).

The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.

What is the relationship between the rate at which molten material cools and a minerals crystals
worty [1.4K]

The answer is; The slower the cooling the larger the crystals

Slow cooling allows the aqueous molecules of the compound to find a perfect geometry and grow into a large crystal. Fast cooling causes impurities to be incorporated into the growing lattice hence atagonizing the growing crystals.

During the process of photosynthesis,
TEA [102]

Answer:

d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds

Explanation:

Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.

During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.

The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.

What is the function of helicase in dna replication? see concept 16.2 (page 322)?
Salsk061 [2.6K]
The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated. Their main role is the separation of double-stranded DNA into single strands allowing each strand to be copied during the process of replication. It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />
