Which of the following statements is true?
Simora [160]

Lines of latitude are often printed to mark off angles
(not distance) north and south of the equator.

Lines of latitude are also called 'parallels', because
they are parallel to each other.

If there are any of them printed on a particular map
or globe, then each one north of the equator is labeled
with the angle it represents, and ' N '.

How can you tell if this problem is a equations ate a parallel or neither y=5x+2 y=5x-1 tell me how to workit
NeX [460]
If the equations have the same slope for example y=4x+2 AND y=4x+3 have the smae slope of 4/1, making them parallel but if the don't have the same slope for example y=2x+3 and y=4x+4 then they are not parallel

20) What wavelength does the Sun emit most of its radiation at, and what is the name of that radiation region? vi'sible micromet
photoshop1234 [79]

Answer:

Visible light range (between 400 and 800 nm).

Explanation:

The Sun emits a large range of electromagnetic waves, from gamma rays (higher frequencies) to radio waves (lower frequencies), through X-rays, ultraviolet rays, visible light, infrared radiation, microwaves. The peak of the Sun's energy output is actually in the visible light range (between 400 and 800 nm).

In the graph I annexed, you can see a simplified representation of the energy emissions of the Sun versus the wavelengths of those emissions. The y-axis shows the amount of energy emitted at a given wavelength and the x-axis represents different wavelengths of EM radiation. In this graph is observable than the major emission of radiation emitted by the Sun is in the visible range.

I hope you find this information useful and interesting! Good luck!

Which would be an adaptation for living in the tundra?
Novosadov [1.4K]

This question is incomplete. Here's the complete question.

Which would be an adaptation for living in the tundra?

funnel shaped leaves to help water runoff

deep roots to go into the permafrost

hibernation to lower metabolism in the winter

large ears to release heat

Answer: hibernation to lower metabolism in the winter

Explanation:

Hibernation is something many animals do to survive in the tundra. They hid in dens for several months during the winter. Their metabolisms get to a dormant state in which their bodies survive thanks to stores of fat gained during the summer. The Grizzly bear is an example of a tundra animal that hibernates during the winter.
