Does protecting animals so they won’t go extinct help with climate change?

Yes

Explanation: Yes it depends on what kind of animal but yes it can help

locations with local extinctions had larger and faster changes in hottest yearly temperatures than those without

270 sec . ( = 4 min . 30 sec . ) Explanation: Any radio wave is moving at the speed of light, regardless of the frequency, so the frequency should be superfluous information. The speed is light is close to 300 , 000 k m s I take the distance you are given, to be 8.2 ⋅ 10 7 k m (since 8.2 ⋅ 107 k m doesn't make good sense - it's less than 1000 km) i.e. 82 , 000 , 000 km.

Before we actually compute this, we can notice that this is a little more than half the distance of the earth from the sun (150 mill. km), a distance the light uses 500 sek. = 8 min 20 sec. to travel, so we should get about 4 1 2 min for the radio wave to reach Mars from the earth.

Actual calculation: 82 , 000 , 000 km/300 , 000 k m s = 820 3 s = 273.3 s As the distance is given with 2 significant figures, we round this off to 270 sec = 4 min 30 sec.

Hope this helps =)
