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.

Answer:
Carbondioxide gas is responsible for global warming and climate change.
Explanation:
The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.

Larvae of the Diamondback moth feed on cauliflower paleo Aunt Farmers commonly used pesticides to repel them all from the cauliflower plants the larvae of the Diamondback moth arnab resistant various types of pesticides which statement best describes how the larvae became resistant?
Answer:
Mutation.
Explanation:
Mutation is the factor that is responsible for the acquiring resistance of various pests against pesticides because in mutation the genetic makeup of the organism changes which has no effect of the chemicals applied on them. Repeated use of the same type of pesticides to control a specific pest can cause changes in the genetic makeup of a pest that leads to another form of pest which causes pesticide resistance in the new type of pest so we can say that mutation is the main cause of resistance in pests.

The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?
Answer:
The layers of the atmosphere are determined based upon air temperature, which has to do with the energy of the molecules in the air. Where does this energy originally come from?
Explanation:
The layers of the atmosphere are determined based on air temperature, the energy in the air molecules comes from the sun, which increases the temperature of the atmosphere.
What are the layers of atmospheres?There are different layers of the atmosphere. There are seven layers of atmosphere. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The sun is the only source of energy for the atmosphere. It provides heat or thermal energy and which is acquired by different molecules and these molecules convert this energy into other forms of energy.
Thus, the energy contained in the molecules of the air is derived from the sun, which raises the temperature of the atmosphere, which in turn determines the layers of the atmosphere.

What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Provide one reason that preventing fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time
Answer:
To produce a healthy offspring.
Explanation:
To make a healthy offspring is the reason that is responsible for preventing fusion of multiple sperm with one egg in sea urchins because if more sperm are fused with one egg, faulty segregation of chromosomes occurs during cell division that leads to the production of nondiploid cells due to which no further development occurs. So by avoiding such type of faults in the cell, only one sperm will fuse with egg not multiple sperms.
That is one reason that preventing the fusion of multiple sperm with one egg in sea urchins has provided a survival advantage over evolutionary time to produce healthful offspring.
To make a healthful offspring is a purpose this is liable for stopping the fusion of more than one sperm with one egg in sea urchins due to the fact if greater sperm are fused with one egg, defective segregation of chromosomes happens for the duration of the molecular department that results in the manufacturing of nondiploid cells because of which no similar improvement happens. So through averting such sort of faults withinside the molecular, best one sperm will fuse with egg now no longer more than one sperms.

What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective breeding?
Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest." Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators. Natural selection is when the "best" trats are passed down due to chance
Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down. Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur
When a system transforms energy from one type to another, the system always experiences
A
energy loss through heat.
B
energy gain through light.
C
mass gain through nuclear reaction.
D
mass loss through chemical reaction.
Answer:
A energy loss through heat
When a system transforms energy from one type to another, the system always experiences energy loss through heat. So the correct option is A.
What is meant by energy loss?Energy is lost when it is changed from one form to another, transported from one location to another, or transferred from one system to another. As a result, part of the energy intake gets transformed into an amorphous form of energy, such as heat, when energy is transformed into a new form.
Functionally, unless one is purposefully converting energy into heat, it is nearly hard to convert all of the energy input into the output energy (like in a heater).
The energy that enters power lines always outweighs the energy that exits at the opposite end of the power lines whenever electrical energy is transferred by power lines.
Processes are never 100% efficient because of energy losses.
As it travels, energy changes significantly and assumes a variety of forms. Every conversion it passes through results in some sort of energy "loss."
Even if this energy doesn't truly vanish, part of it changes into forms that we can't utilize or don't want to use. Therefore the correct option is A.

(10pts)
Answer:
Your cell use passive transport whereas your colleague cell use active transport.
Explanation:
There is a great difference in the type of transport between your experiment and his because you provide no ATP to the cell for transport means you use passive transport in which the cell moves molecules without the use of energy while on the other hand, your colleague provides ATP to the cell means the cell transports molecules with the use of energy so the cell use active transport. The characteristics of molecules have the presence of both type of cells which do both type of transport.
