Answer:

False

Explanation:

In air, sound propagates in the form of longitudinal waves, that is, the direction of the oscillation coincides with that of the wave's propagation.

An oscillating body sets the air molecules around it in motion. These, in turn, transmit that movement to neighboring molecules, and so on. Each air molecule oscillates around its resting point. That is, the displacement that each molecule undergoes is small. But the movement spreads through the medium.

Between the sound source (the teacher) and the receiver (the student) there is an energy transmission but not a transfer of matter.

A Tropical Rain Forest biome is normally limited to low altitudes near the equator.
Kay [80]

Answer:

True

Explanation:

Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between  fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.

Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.

Why does transcription occur in the nucleus and not in the cytoplasm in eukaryotes?
pav-90 [236]
Transcription is the process by which the DNA molecule makes an RNA molecule using enzyme RNA polymerase and other proteins. The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus.
