There are many lines of evidence which clearly show that the atmospheric CO2<span>increase is caused by humans. The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half). There is no question whatsoever that the CO2 increase is human-caused. This is settled science.</span>
<span>In 1944, Oswald Avery identifies DNA (Deoxyribonucleic Acid) as transforming principles. This famous genetic scientist has made great efforts for many steps to find what happened after combinations of some bacteria. After purification, he found a new substance which was a nucleic acid, involving the discovery of DNA after further analysis.</span>
Answer:
Minerals all have a solid chemical compound that occurs naturally in pure form.
Answer: Kidneys, intestine and skeletal system
Explanation:
Parathyroid hormone is the hormone that is responsible for regulation of the calcium levels in the extracellular fluid in the body.
It exerts influence over the skeletal system to reabsorb the calcium by the oesteoclasts. It causes the reabsorption of the calcium by the small intestine. It also prevents the excretion of calcium through urine by reabsorption by renal tubules.
This change best illustrates the 3rd answer choice, Loss of Habitat.
The plants aren't migrating, but are rather only surviving in areas where there is enough moisture to support life. The wildflowers are not adapting to grow in dryer conditions, and the species is not going extinct, as there are still some areas where the plants can get enough moisture.
Hope this helped!
