Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.
Kelp plants have been known to grow up to C. 10 inches per day.
It really depends of how much sunlight they get, because these rays help kelp plants produce food and the necessary nutrients. With the help of sunlight, these plants can grow faster.
By studying the population over an extended period of time, scientists can discover the change in number of population and its growth.
Florida panther population is listed as endangered, but it is estimated that the number is recovering. The population had grown from about 25 adults in 1995 to roughly 100 in 2010. The updated estimates from the 2017. calculated the number between 120 – 230 panthers which is still not a sustainable population size.
