What hypothesis did Miller-Urey test in their experiment?
Answer: The Miller - Urey experiment is an experiment that was conducted by Stanley Miller and Harold Urey last 1950's. The hypothesis that they had tested and demonstrated was that several organic compounds could be formed by simulating the conditions of Earth's atmosphere.The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.

All of these events are characteristic of an El Niño event except:
A- the Midwestern United States experiences more rainfall than usual.
B- the usual South America-to-Southeast Asia winds ease.
C- South Africa, Japan, and Canada experience warmer than usual weather.
D- ocean surface temperatures are lower than usual.
E- storms form off the coast of California.
Answer:
B- the usual South America-to-Southeast Asia winds ease.
Explanation:
The usual South America-to-Southeast Asia winds did not blow from west to east because of El Nino event. In normal condition, the winds blow easterly from South America-to-Southeast Asia which means from west to the east direction but due to El Nino event, the wind blows is reversed which causes the blowing of winds towards westerlies which means from east to the west direction so the usual blowing of winds from South America-to-Southeast Asia did not occur.

Describe how individual cell breakdown energy rich molecules to provide energy for cell functions
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Explanation:
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called 'cellular respiration'. The process is happens in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

If the birth rate and death rate are balanced in a population, how might a population increase in size?
I
Answer:
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow
Explanation:
Natural increase in a population occurs where Birth rate is greater than death rate. ... Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline
The population will be doubled by immigration. The correct option is C.
What is immigration?When an animal settles down in a habitat because it has resources nearby or because it is a good fit for them, this is referred to as immigration.
When an animal emigrates, it's because its habitat is no longer perfect for it and it needs to move to a new location with a better habitat.
It is the quantity of members of the same species that have entered the habitat during the time period under examination from outside the habitat.
To immigrate means to move permanently to another country. To migrate is to move, much like wintertime birds. Depending on the viewpoint, one can either migrate, immigrate, or emigrate.
Immigration can increase the size of a population if the birth and death rates are equal.
Thus, the correct option is C.

Fresh steak is said to have both negative and positive redox potential. Discuss how the redox potential affects the microbial ecology of the food
Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.

Answer:
espero que te sirva
Explanation:
El calentamiento global y el cambio climático tienen coincidencia en la principal
de sus causas, la emisión masiva de los diferentes gases de efecto invernadero o
GEI que retienen el calor dentro de la atmósfera y sobre la superficie terrestre a
través del denominado efecto invernadero.
El efecto invernadero es un proceso natural por el cual se produce la retención
del calor procedente del Sol en la atmósfera terrestre gracias a la capa de GEI que
se encuentra en ella. Estos gases en cantidades normales mantienen la
temperatura del planeta aproximadamente a 33ºC por encima de la que podría
tener si estos no existieran, por lo que el planeta sería demasiado frío para que se
desarrollase vida en él. Sin embargo, actualmente el efecto invernadero se está
volviendo tan intenso a causa de nuestras emisiones que comienza a tener graves
repercusiones en el medio.
El Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC)
concluyó en el Quinto Informe de Evaluación (AR5) de 2013 que la influencia
humana había sido la causa dominante de este calentamiento producido desde la
mitad del siglo XX a través de la emisión de GEI, lo cual es una evidencia cada vez
mayor. Entre los principales gases emitidos se encuentran el vapor de agua, el
dióxido de carbono, el metano y el ozono.

Which of the following is not a property of fibre?
O a. It delays gastric emptying
Ob.it
It provides a feeling of satiety
O c It elevates blood glucose levels
O d. It contributes 6-10 kilojoules per gram.
Answer: The correct option is C ( It elevates blood glucose levels).
Explanation:
All animals feed on ready - made food. This food is made up of several groups of substances.All food taken in by an animal can be divided into six groups of food substances or nutrients. They are carbohydrates, proteins, fats and oil, mineral salts, vitamins and water.
Fibres is defined as foods that are usually of plant origin which are indigestible and stimulates movement of the bowels by providing bulk to the intestinal content.
Examples of the plant based food which are rich in fibre include:
--> grains,
--> fruits,
--> vegetables,
--> nuts, and beans.
Fibre is further divided into two:
--> Insoluble fibre: This is also called roughages. They include fruits and vegetables with their backs, whole grains.
--> Soluble fibre: This is the jelly-like fibre that dissolves in water. It includes the flesh of fruits and vegetables, oats.
All fibers can slow the absorption of sugar and fat from food, and therefore help prevent spikes in blood sugar. Therefore the option that fibre elevates blood glucose levels is NOT a property of fibre.
Answer:
c It elevates blood glucose levels
Explanation:
Elevation of blood glucose levels is not the property of fiber because fiber helps control blood sugar. Fiber can't be converted into glucose or fiber does not have glucose so the concentration of glucose can not be increased if more fiber is eaten. Fiber provides a feeling of satiety as well responsible for gastric emptying. One gram of fiber produces 8 kilojoules per gram. So we can conclude that blood glucose level can't be increases due to fiber.
