Fossils are the remains of prehistoric plants or animals embedded and preserved in rocks. They are preserved by three main methods: unaltered soft or hard parts, altered hard parts, and trace fossil.
Soft-tissue original remains are very rare except as captured in amber, trapped in tar, dried out or frozen in permafrost.
Amber is ancient tree sap that can trap flowers, worms, insects as well as small amphibians and mammals and preserve them whole.
Permafrost is an area of land that is permanently frozen below the surface. It is common in Siberia (part of Russia) and in Alaska. Many different kinds of frozen extinct as well extant animals have been found in Siberian permafrost, including woolly mammoths, horses and bison, and lions.
Tar or asphalt is a liquid found naturally in small pits in swamps. These pits are formed from crude oil seeping through the ground. The lighter elements of crude oil evaporate leaving thick sticky asphalt. Animals that fall into these pits hardly escape and their bodies are preserved within. Fossils of animals such as wolves, short-faced bears, American lions, ground sloth and saber-toothed cat have been found preserved intact in tar.
The correct answer is "antagonist". A neurotransmitter is a chemical substance of the human body responsible for neurotransmission. Once released from the presynaptic neuron, they bind to specialized receptors located on the postsynaptic neuron. This binding triggers a specific response at the receiving cell. An antagonist drug reduces the effects of a neurotransmitter by binding to the specific receptor and preventing the binding of the neurotransmitter.
It is MOST likely that Assad and Juana believe that <u>nature</u> is the major contributor to their child’s development.
Nature is the one which we perceive to be pre-cleaning and is impacted by genetic heritage and some other biological factor. Nurture is usually taken as the effect on a person by environmental factors after birth, like the result of exposure, personal experiences, and learning.
From the birth itself the method of interacting with children, the type of teaching they had, contribute a lot in deciding the nature of children. For this outer factors like parenting, schooling, exposure and tragedies which take place in personal level impact the structure of nature.
