Answer:Option A
Explanation:
Even though microwaves have a little more energy than radio waves, infrared wave has more.
Infrared waves have lower frequency than microwaves. Even though microwaves have a little more energy than radio waves, infrared wave has more.
What is electromagnetic waves?Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light. Radio waves, micro waves, infra red and ultraviolet are all electromagnetic waves.
It is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa for higher wavelength, the electromagnetic wave will also have lower frequency.
Therefore, Infrared waves have lower frequency than microwaves. Even though microwaves have a little more energy than radio waves, infrared wave has more.

What is true about the current extinction rate?
A.
It’s slower than the earlier mass extinction rate.
B.
It’s primarily attributed to human intervention.
C.
It’s attributed to natural environmental changes.
D.
It’s necessary for evolution.
E.
It’s affecting few species.
Answer:
its b
Explanation:
Extinction is primarily attributed to human intervention. So, the correct option is B.
What is Extinction?The extinction is defined as the end of a particular type of organism or a set of types, typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is usually considered as the moment of extinction.
Extinction is the term used to describe the extinction of an entire species. In that it has allowed for the emergence of new species and the ascent of others, extinction has both advantages and disadvantages. Since most species have been driven to extinction by human activity, humans have had a significant impact on the pace of extinction. The main cause is thought to be human activity.
Therefore, the correct option is B.

The energy from the sun is produced in the core through the process of nuclear fusion. The photons travel through the sun and are released as radiation which travels to the earth. How long does it take to reach the earth?
Answer:
8 min 20 seconds
Explanation:
Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.

When ice freezes, the water around it becomes saltier and colder. _______, it's density increases.
A Therefore
B On the other hand
С In contrast
D Especially
When ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).
What is Density?
Density is defined as the mass per unit volume of a substance and is denoted by ρ, although the Latin letter D may also be used.
Density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where ρ is density, m is mass, and V is volume. It has the units of mass divided by volume such as grams per centimeters cube [tex](g/cm^3)[/tex] or kilograms per liter (kg/l).
When water changes from a liquid to a solid state that is liquid in the form of ice, its density will increase as it becomes saltier and colder.
Thus, when ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

A pelican is hunting for fish as it flies above the surface of the water. Why must the pelican alm for the fish in a slightly different place in the water than where the fish appears to be
located?
Answer:
I'm not sure but maybe because if the pelican goes exactly where the fish is the fish will naturally move forward to escape so instead of catching the fish the pelican would get a mouth full of water. If the pelican aims for a spot a little different then where the fish actually is the pelican can might catch it because the fish went to its direction. (sorry if that's not correct)
