g If a colony of bacteria starts with 1 bacterium and doubles in number every 20 ​minutes, how many bacteria will the colony con
Lynna [10]

Answer: 2.81 x 10∧14 baterias after 16 hours.

Explanation:

Hi, first we have to find how many 20 minute intervals are in 16 hours.

If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)

If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)

There are 48 twenty minutes intervals in 16 hours.

Now we have to apply the exponential growth formula:

P (t) = Po (1 +r) ∧t

Where:  

P (t) = population at time t  

P (0) = initial population (1)

r = growth rate (1)

t = time (48)

Replacing with the values given:

P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14

2.81 x 10∧14 baterias after 16 hours.

Fossils of the same organism found in widely separate areas can tell scientists a lot about the ancient?
Levart [38]

Answer:

Ancient landmasses

Explanation:

The same fossils being found in widely separate areas can help scientists infer the geography of the continents of that time.

For example: Africa and South America used to be connected during the Permian Period.

Scientists can confirm this because both continents are home to similar fossils.

Compare temperature and pressure conditions on the Earth's surface to those below the Earth's surface, and relate these conditio
Ivahew [28]

Answer:

Explanation:

The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.
