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>
Answer:
D
Explanation:
To make the passage more descriptive, including information about Lil's garden could help.
The correct answer is C. remember your topic and stay focused.
It's incredibly easy to get off track when doing a project, so you should always try to focus on a central idea or main point. If you get off track or begin researching other things, you can lose the meaning and purpose behind your work.
Hope this helps! :)
