Answer:

Se explanation

Explanation:

Mechanical waves are waves that require a material medium for propagation e.g sound waves and waves on a spiral spring.

Electromagnetic waves do not require a material medium for propagation. They can travel through space.

The light and heat of the sun are far away in outer space yet they reach us on earth. There is no intervening medium between the earth and the sun that conducts its rays to the earth. As a result of this, we can conclude that the rays from the sun are electromagnetic waves.

why are less massive stars thought to age more slowly than more massive stars, even though less massive stars have much less fue
kaheart [24]
It is believed that a less massive star will age more slowly than a more massive star, despite the fact that massive stars have much more fuel. The reason that a more massive star will burn out quicker is because it takes a significant more amount of energy to keep the star burning due to the increased diameter of the star compared to the less massive star. A less massive star will use its fuel less quickly due to being smaller and having less mass to fuel.

The massive star burns its fuel at a greater rate than the less massive star.

The characteristic that best helps define an organism as a member of a particular species is which of the following?
lapo4ka [179]

If they are able to reproduce they will produce fertile offspring.

Species is defined as a group of organisms that can interbreed and produce fertile offspring. This means that if two organisms can have offspring and if those offspring can reproduce and produce offspring they are of the same species. Measured by the number of species insects certainly make up the largest proportion of living organisms in the world. Over one million species of insects have been documented and studied by scientists.    

A population is a group of organisms of the same species living in the same area at the same time. A species is a type or type of organism. For example, all humans belong to one species the scientific name for our species is Homohis sapiens and are distinct from other species such as gorillas dogs and dandelions. The concept of morphospecies states that species are distinguished from other species by physical characteristics and can be identified by morphological characteristics.

Explain how sediments eroded by the water in this stream become smoother and rounder in shape
bonufazy [111]
The sediments rub together to become smoother. Sediments which are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round after a while.
