djverab [1.8K]

Answer:

Option C, Correct Behavior genetics

Explanation:

Behaviour genetics is the study of the influence of both genes and environment on the behaviour of an individual. This study is done to understand how both genes and environment together affect the behaviour of an individual. It is believed that all forms of behaviors are either inherited or learned. Mr. Hill is noting the concordance rates of music ability  for both biological children (who might have inherited this ability from their parents) and adopted children (who might have learned this ability from the musical environment around them)

Hence, option C is correct

Explanation:

electromagnetic waves: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

radio waves: Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.

microwaves: Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.

infrared: Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.

visible ray: The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers

ultraviolet:UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes

xray:An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz)

gama ray :A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.

Which environmental changes are considered short term? Check all that app
kvv77 [185]

Answer: floods,  forest fires, earthquakes

Explanation:

The short term changes are those changes that affects the organisms immediately. The effect of these changes remain for short duration. Thus the environment and the living beings adapt the changes. A flood can wipe out the terrestrial ecosystem, the ecosystem will regain its original form when the water level depletes. Forest fires may kill several trees and animals in an ecosystem. But some plants and animals will sustain which can give birth to new colonies. The earthquakes affect the earth crust and biosphere. The earth crust may get stabilize again by filling up the crater and biosphere will also promote of living beings.
