Answer:
To store genetic information to pass on to other living organisms.
The answer is electron microscope, the magnification can be so high that it can be very expensive, most schools doesnt have them, mostly found in universities or some laboratories. the ones we usually use in home or schools are light microscope
Maria and craters are explained below:
<u>Explanation:
</u>
- The Moon is divided into light area lunar highlands and a dark area called Lunar Maria.
- Lunar Maria is large, dark, basaltic plains formed on earth's moon formed by ancient volcanic eruptions.
- Craters are formed when an impacting object falls and hits the moon's surface with greater speed and also formed as a result of the outward explosion of rocks.
- Craters are often caused by asteroids and meteorites with the lunar surface.
- Unlike earth-moon does not have an atmosphere to protect itself from impacting bodies. This is the reason for more number of craters formed on earth.
Answer:
In order to find average speed during each interval, we need to divide the distance during those intervals with the period of time. So, for the first interval (day 0 to day 2) hawksbill started from 0 and reached 10 kilometers by the end of the second day. That means that it crossed 10 kilometers in 2 days, so the average speed is 10/2 which is 5 km/day. Similarly, we can calculate speed for other intervals:
• day 2 - day 3: it went from 10 to 12 km in one day, which means it crossed 2 km in one day, so the average speed is 2/1 = 2 km/day
• day 3 - day 4: at the end of the third day it reached 12 km and at the end of the day 4 it remained at 12 km. That means the hawksbill wasn't moving in that interval so the speed was 0
• day 4 - day 5: it went from 12 km to 18 km, which means it crossed 18-12=6 km in one day, so the average speed is 6/1=6 km/day
• day 5 - day 6: it went from 18 to 24 km, which means it crossed 24-18=6 km in one day, so the speed was 6/1=6 km/day
So, to summarize, during the first interval turtle was moving with average speed of 5 km/day, then 2 km/day, in the third interval it wasn't moving and in the last two intervals, it moved in average speed of 6 km/day.
