Radiation is the  mechanism of heat transfer by which heat travel in a straight line at the speed of light, allowing heat to travel through vacuums and air spaces.

Radiation in physics is the emission or transmission of energy in the form of waves or particles through space or matter medium. This includes:

  • Electromagnetic radiation such as radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays (γ)
  • Particle radiation beams such as alpha rays (α), beta rays (β), proton rays, and neutron rays (with static energy non-zero particles)
  • Acoustic Radiation such as ultrasound, sound waves, seismic waves (due to physical transmission media)
  • Gravitational radiation in the form of gravitational waves, or waves of curvature of space-time

Radiation is often classified as either ionizing or non-ionizing, depending on the energy of the particles it hits.

Which hypothalamic hormone contributes to the regulation of the male reproductive system? a. luteinizing hormone b. gonadotropin
Lostsunrise [7]

Answer:

The correct answer is option b. gonadotropin-releasing hormone.

Explanation:

The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.

GnRH regulates both gonadotropin hormones, in which, LH (luteinizing hormone) responsible for the regulation of the male reproductive system and FSH (follicle-stimulating hormone) responsible for the female reproductive system and sperm production in testes in males.

Thus, the correct answer is option B. gonadotropin-releasing hormone.

lesya692 [45]

Explanation:

Wind energy is one of the sources of renewable sources of energy that is environmentally friendly.

It uses wind power to generate other forms of energy mostly electricity.

Some of the drawbacks are:

  • Wind turbines pose serious threat to wildlife. It is common place to see dead birds in areas where wind power is being harnessed.
  • The quantity fluctuates from time to time. Since wind is an element of weather, it is not always in regular supply as desired.
  • The cost of constructing wind turbines can be very high a times.
