2. ultraviolet waves (UV Rays)
- smaller frequency and higher energy than visible light- between 400 nanometers and 10 nanometers
- the sun emits UV rays - they cause sunburn
3. X-rays
- higher energy and frequency than UV rays
- X-rays can pass through skin and flesh, but not through bone, so they are used to examine bones

Answer:
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates
Explanation:
Nucleic acid is an important macro molecule that deals with storing and expressing genetic information. The information is encoded by Deoxyribonucleic acid for making essential proteins.
Lipids are structural components of cell membrane which store energy. They are also known as fats.
Proteins is responsible for regulating all cellular process. It is the building block of any organism
Carbohydrates when broken down into glucose release energy and hence they are the major source of energy for our body.
Hence, the correct pair is
Store and transmit genetic information: nucleic acid
Are primarily used to store energy: lipids
Help regulate cell processes: proteins
Are used for main source of energy: carbohydrates

HELP ITS TIMED!: Duchenne muscular dystrophy is caused by a recessive allele located on the X-chromosome. Two unaffected people have a child with Duchenne muscular dystrophy.
What is the genotype of the mother?
Question 2 options:
XDXD
XDXd
XdXd
Answer:
XDxd
Explanation:
the recessive allele for the disease is represented by (d).
the dominant allele for not having the disease is represented by (D)
in order to not be affected, we know that the mother must have one uppercase D, so the last option is wrong. And in order to pass it on to her child, she needs one lower case d (to give to the child). So the second answer is correct. good luck :).

What could be the effects of a population changing drastically over a short period of time?
Answer: Causes of population decline
The size and demographics of the population change when:
fewer children are born;
families with children move to larger towns and cities;
young and better-educated people move to larger towns and cities.
Effects of population decline
When young people move to bigger towns and cities, the average age of the population in the place they leave behind automatically goes up. A community with a higher proportion of older inhabitants may be less attractive to businesses, which may additionally have difficulty finding suitable staff locally. Other effects of population decline include:
fewer schools, due to there being fewer children;
a drop in house prices because more homes are unoccupied;
fewer new homes being built;
less demand for rented accommodation;
fewer care facilities;
less turnover for shopkeepers and businesses;
fewer sports facilities;
fewer people going to the theatre, cinema or concerts, so these facilities are eventually cut back;
fewer people travelling by public transport, which thus costlier to run;
local residents have to travel further to reach the facilities they want.
