Answer:
Why is internal Fertilisation important to animals?
Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young.
Explanation:
Answer:
Anemometer
Explanation:
It should be understood that the anemometer is different to wind vane in both structure and function.
This is because, anemometer is an instrument that is used to measure the speed of the wind, while the wind vane is used to measure the direction of the wind.
Therefore, in this case, the anemometer is going to be the instrument to measure the speed of the wind above the ocean waters.
Answer:
Varicella-zoster virus
Explanation:
Varicella-zoster virus (VZV) is a virus with double-stranded DNA as its genome. It is a member of the family Herpesviridae. The virus causes chickenpox in children. It is mostly present in the latent form after the disease subsides and the same virus can cause shingles in adults under specific conditions. Therefore, shingles is also called a reactivated form of chickenpox caused by the latent varicella-zoster virus. The virus has an incubation period of 10 to 23 days and causes the formation of pus-filled small vesicles on the face or upper trunk.
Explanation:
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
Answer:
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.
