Human activites have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered Altered biogeochemical cycle combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
b. Natural selection is an example of the major mechanism by which evolution occurs
Explanation:
The concept of evolution are both closely related in that natural selection is the major mechanism by which evolution occurs. This was proposed by Charles Darwin after his journey to the Galapagos Island on the HMS Beagle.
- Evolution is the change in the characteristics of an organism over several generations.
- Organisms evolved to in order to be at an advantage and naturally favored.
- According to Charles Darwin, organisms evolved by the process of natural selection.
- Natural selection is the process by which an organism becomes adapted to its environment.
- Organisms with desirable trait are naturally favored with competitive and reproductive advantage in the environment.

Hey there!
First when adding fractions, you have to have the same denominator
So, the least common multiple or LCM is 12 because
6, 12
And
4, 8, 12
They both match at 12 so that is the LCM or denominator.
Now since you multiplied 6 * 2 = 12 and 3 * 4 = 12
Multiply the numerator by the same number.
So 1/6 * 2 = 2/12
And
3/4 * 3 = 9/12
<u>Your answer is 11/12</u>
Hope this helps

Answer: amino acids --> proteins --> cells --> tissues --> organs
Explanation: Amino acids are monomeric units of proteins. Amino acids are building blocks of proteins, they aggregate to form proteins. Proteins are components of a cell, a group of cells make up a tissue and a group of tissue make up an organ.
