Answer: People appear to have arrived by sea during a period of glaciation, when New Guinea and Tasmania were joined to the continent of Australia. The minimum widely accepted timeframe for the arrival of humans in Australia is placed at least 40,000 years ago. Many sites dating from this time period have been excavated.

59 minutes

Explanation:

There is 1 hour (equivalent to 60 minutes) between 11.00pm and midnight.

Using the formulae; P <em>(future</em>) = P <em>(present)</em> * (1 + <em>i</em>)ⁿ where

P <em>(Future) </em>= Future Population

P <em>(Present)</em> = Present Population

<em>i</em> = Growth Rate

n = Number of generations

The bottle was full after 60 minutes and it was filed by the following number of bacteria

P<em>(future) </em>= 1 * (1+1)⁶⁰ = 1,152,921,504,606,846,976

A half-filled bottle would have half the number = 576,460,752,303,423,488

Using the same formulae to find after how many generations do we get to this number;

576,460,752,303,423,488 = 1 * (1+1)ⁿ

(576,460,752,303,423,488) / 1 = (2)ⁿ

n = log₂ (576,460,752,303,423,488)

n = 59

This means the bottle got full at 59 minutes.

How does deforestation have an affect on the water cycle?
andre [41]

Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding.
