Take a subject of origins or a question you have and write a minimum of 500 words as a research project. Be sure to list all references and resources as part of your bibliography. Other information can be found at a library or other reference source. (It has to be the creation theory because I go to a christian school.)
Answer:
Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup? One theory involved a "shocking" start. Another idea is utterly chilling. And one theory is out of this world! Inside you'll learn just how mysterious this all is, as we reveal the different scientific theories on the origins of life on Earth.Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well. The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now. The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.
Explanation:
Species that evolved in coral reef habitats always stay in those habitats. Coral reefs have much biodiversity, but most species that live there migrated from other habitats. Most organisms that live in coral reef habitats are zooxanthellae. More new species have evolved in coral reef habitats than in most other types of habitats.
Answer:
Most organisms that live in coral reef habitats are zooxanthellae.
Explanation:
zooxanthellae are the single-celled dinoflagellates that lives in mutual relationship with corals, jellyfish, and nudibranchs. These organisms have a mutualistic relationship between zooxanthellae and corals. Coral produces carbon dioxide and water in the process of cellular respiration while on the other hand, the zooxanthellae use this carbon dioxide and water to carry out photosynthesis for making their own food like plants so both the organisms get benefit from one another.
Which neurotransmitters are used for each division of the autonomic nervous system? Be sure to describe the synapse at the autonomic ganglion and at the effector. What component of the system determines if a given neurotransmitter has an excitatory or inhibitory effect on the target effector?
Answer:
The autonomic nervous system is in charge of controlling visceral effectors. Traditionally, it is described by its peripheral nervous components (ganglia, nerves and plexuses) and two divisions are distinguished: the sympathetic and the parasympathetic. Transmission of the excitatory stimulus through the synaptic cleft occurs by release of neurotransmitters; the neurotransmitters of the sympathetic and parasympathetic nervous system are mainly norepinephrine (NA) and acetylcholine (AC). The NA-secreting fibers are called adrenergic and those that secrete AC, cholinergic. All preganglionic neurons, both those of the sympathetic nervous system and those of the parasympathetic nervous system, are cholinergic. The neuron that releases the neurotransmitter is called a presynaptic neuron. The signal receptor neuron is called a postsynaptic neuron. Depending on the type of neurotransmitter released, postsynaptic neurons are either stimulated (excited) or de-stimulated (inhibited).
Explanation:
The autonomic nervous system is the part of the central and peripheral nervous system that is responsible for the regulation of the involuntary functions of the organism, the maintenance of internal homeostasis and the adaptive responses to variations in the external and internal environment and two divisions are distinguished: the sympathetic and the parasympathetic. Acetylcholine is the preganglionic neurotransmitter of both divisions of the S.N.A. (sympathetic and parasympathetic) and also of the postganglionic neurons of the parasympathetic. The nerves at whose endings acetylcholine are released are called cholinergic. Norepinephrine is the neurotransmitter of postganglionic sympathetic neurons. The nerves into which norepinephrine is released are called adrenergic. Within the efferent sympathetic impulses, the postganglionic neurons that innervate the eccrine sweat glands and some blood vessels that supply the skeletal muscles are of the cholinergic type. Both acetylcholine and norepinephrine act on the different organs to produce the corresponding parasympathetic or sympathetic effects. The peripheral nerve endings of the sympathetic form a reticulum or plexus from which the terminal fibers come in contact with the effector cells. All the norepinephrine in peripheral tissues is found in the sympathetic endings in which it accumulates in subcellular particles analogous to the chromaffin granulations of the adrenal medulla. The release of norepinephrine at nerve endings occurs in response to action potentials that travel through nerve endings. The receptor, when stimulated by catecholamines, sets in motion a series of membrane changes that are followed by a cascade of intracellular phenomena that culminate in a measurable response. There are two classes of adrenergic receptors known as alpha and beta. These two classes are again subdivided into others that have different functions and that can be stimulated or blocked separately. Norepinephrine primarily excites alpha receptors and beta receptors to a small extent. The neurotransmitter acetylcholine is synthesized at the axonal terminal and deposited in synaptic vesicles. Acetylcholine activates two different types of receptors, called muscarinic and nicotinic receptors. Acetylcholine (AC) synthesis takes place at presynaptic termination by acetylation of choline with acetyl-coenzyme A, a reaction catalyzed by acetylcholinetransferase. The energy required for the release of a neurotransmitter is generated in the mitochondria of the presynaptic terminal. Binding of neurotransmitters to postsynaptic membrane receptors produces changes in membrane permeability. The nature of the neurotransmitter and the receptor molecule determines whether the effect produced will be one of excitation or inhibition of the postsynaptic neuron.
Suppose that millions of years from now Australia moves to South America. Would Australia still have the same kinds of mammals? Explain your answer.
Answer:
Which best explains why Australia has life forms that do not exist anywhere else on Earth? Australia was separated from the other landmasses by geological forces. Scientists think that dolphins and whales may have evolved from a common ancestor.
Assuming that millions of years from now Australia moves to South America. Australia would not have the same types of mammals, because with the junction of the continents new conditions would suggest for animals to evolve.
What was the evolution of continents?Continental Drift is a theory that claims that, at one time, all the present-day continents formed just a single landmass, called Pangea. This supercontinent, thanks to the movement of the Tectonic Plates, fragmented several times until it provided the current shape of the land masses.
With this information, we can conclude that millions of years from now Australia will move to South America. Australia would not have the same types of mammals, as with the joining of the continents new conditions would suggest the evolution of animals.
