Explanation:
The energy emitted by long wavelength waves are smaller to those emitted by short wave lengths.
The energy of a wave is a function of its wavelength and frequency.
- The wavelength of a wave is the distance between its crest.
- Frequency is the amount of waves that passes through a point in a period of time.
- Energy of a wave is directly proportional to frequency and inversely proportional to wavelength.
- The higher the frequency of a wave, the more the energy.
- Waves with a high wavelength carries very little energy.
- Long wavelength radiations have a long wavelength as the name implies. They carry very little energy and have low frequency. Examples are infra-red.
- Short wavelength radiations have short wavelength. They carry very high amount of energy and have very high frequency. Examples are x-rays and gamma rays.

“His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.”

I mean that's what you teachers probably think the answer is but only a very hopeless and sad person should think evolution exist, if it did, why isn't happening today, or why don't we see changes.
Answer: Blood is slightly more viscous then water, pH is slightly alkaline it is about 8% of ones body total body weight the rest of the options are slightly wrong.
Explanation: Blood is red in colour, a dark red when it is deoxygnated and bright red when oxygenated. Its normal pH is 7,4 making it slightly alkaline and it accounts for 8% of one's total body weight with 92% being water. Its temperatures ranges around our normal body temperature which is 37°C.
