If I'm right, Brainliest?
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
Answer:
Exposed
Explanation:
When the ice age ended, the glaciers slowly retreated until they reached their current extent limited to the polar regions and alpine mountain climates. The land covered by ice had also been depressed by the weight of the massive glaciers and consequently began to rebound in the centuries following the retreat of the ice sheets. These once frozen lands also turned into large boreal forests with rich ecosystems.
The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.
Answer:
The temperature begins to increase with altitude in the stratosphere. This warming is caused by a form of oxygen called ozone (O3) absorbing ultraviolet radiation from the sun.The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude.
