Its based on radiometric age-dating of meteorites material and is consistent with the radiometric ages of the oldest known terrestrial and other lunar samples
Answer:
The statement, that is, the fossil record does not contain any fossil remains of plants, only animals is false.
Explanation:
Any trace of past life is termed as the fossil. It can be an organism's remains like shells, plants, bones, or teeth. Any activity of an organism like burrows, footprints, and feces can be known as a fossil record. Five different ways by which the formation of a fossil takes place are natural casts, permineralization, trace fossils, amber preserved, and preserved remains.
The formation of a fossil distinctly takes place, however, the majority of them formed when an animal or plant dies in a watery environment and gets buried underneath the silt and mud. In the process, the soft tissues quickly get decompose and leave behind the shells or hard bones. With time accumulation of sediments takes place over the top and solidifies into a rock.
<span> "The process of ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulates in the atmosphere where it causes global warming. But it also affects the oceans. As carbon dioxide enters the ocean it reacts with sea water to form carbonic acid!"</span>
Answer:
D. Adrenaline
Explanation:
Adrenaline hormone is secreted by adrenal medulla during stressful conditions. The hormone is involved in preparing the body for stressful conditions by intensifying the sympathetic response.
If a person is chased by a dog, the adrenaline hormone is released from the adrenal medulla. The hormone triggers the preganglionic neurons of the sympathetic division of the autonomous nerve system to generate the flight or flight response.
Adrenaline increases the heart rate, blood pressure, and blood flow to skeletal muscles and adipose tissues. The hormone also triggers the dilation of airways and increases the blood levels of glucose and fatty acids.
