Hello what’s the question? So I can help you.
Answer: The value of six in 678 is 600
Explanation:The six is in the hundreds place
Answer:
Compared with human vision, these snakes can sense electromagnetic waves that have:
3. a lower frequency and a longer wavelength.
Explanation:
Human eyes are not able to detect the infrared region of the electromagnetic spectrum. We can experience it as heat when, for instance, we get close to a hot object. <u>The snakes mentioned in the passage, however, have special sensory organs that can detect infrared, which means they sense waves that have a lower frequency and a longer wavelength than the ones visible to us. Let's compare infrared to what is detectable by human eyes:</u>
<u>Visible: wavelength: 400 nm – 700 nm; frequency: 790 THz – 430 THz.</u>
<u>Infrared: wavelength: 700 nm – 1 mm; frequency: 430 THz – 300 GHz.</u>
<u>The longer the wavelength, the lower the frequency.</u>
I believe that the exposition in the paragraph is 'Causal analysis.'
