Answer:

C) ions or free radicals, highly reactive species that can cause undesirable effects in living tissue.

Explanation:

Ionizing radiation is a type of energy released by atoms in the form of electromagnetic waves or particles

When a cell absorbs radiation, there are four possible effects on the cell.

• The cell may suffer enough damage to cause loss of proper function, and the cell will die.

• The cell may lose its ability to reproduce itself.

• The cell’s genetic code (i.e., the DNA) may be damaged such that future copies of the cell are altered, which may result in cancerous growth.

• The absorption of radiation by a cell may have no adverse effects.

The detrimental effects of ionizing radiation (IR) involve a highly orchestrated series of events that are amplified by endogenous signaling and culminating in oxidative damage to DNA, lipids, proteins, and many metabolites. Despite the global impact of IR, the molecular mechanisms underlying tissue damage reveal that many bio molecules are chemo selectively modified by IR

Hence the correct answer is C.

What requirement must a force acting on a object satisfy in order for the object to undergo simple harmonic motion?

viktelen [127]

Answer:

Simple harmonic motion is the movement of a body or an object to and from an equilibrium position. In a simple harmonic motion, the maximum displacement (also called the amplitude) on one side of the equilibrium position is equal to the maximum displacement.

The force acting on an object must satisfy Hooke's law for the object to undergo simple harmonic motion. The law states that the force must be directed always towards the equilibrium position and also directly proportional to the distance from this position.

What are some actions that can be taken to remedy air pollution? Select all that apply. Run your air conditioner at a higher set

Sati [7]

Answer: Government passing regulatory laws

Car emissions testing

Carpooling and less driving overall

Air pollution results when a mixture of particles and gases that can reach in harmful concentrations both outdoors as well as indoors. This increase in concentration can lead to rise in the temperatures and global warming it is also related with the health hazards. Soot, smoke, pollen, carbon dioxide, carbon monoxide and methane are the examples of the common pollutants.

Government passing regulatory laws: The government can ban some of the fossil fuels to prevent air pollution, and some vehicles which are likely to emit more partially combustible gases.

Car emission testing: Nowadays, cars and other vehicles are equipped with catalytic converters which converts the uncombustible gaseous products into less harmful gases which are emitted from the vehicle. The car gas emission testing should be performed to either allow a vehicle or ban the movement of the vehicle.

Carpooling and less driving overall: Carpooling is the sharing of one vehicle with more than one individual. This will prevent the need of others to drive another vehicle. The less the number of vehicles on the road the lesser will be the emission of gases and less pollution will be caused.

If the mass of a material is 47 grams and the volume of the material is 15 cm^3, what would the density of the material be?

uranmaximum [27]

Density is calculated as mass per unit volume. In this case, since the material has a mass of 47 grams and we have the volume of 15 cm^3, we can simply divide the values:
Density = 47 grams / 15 cm^3 = 3.1 g/cm^3
Therefore, the material has a density of 3.1 g/cm^3
