Gregory is making a turkey for Thanksgiving by roasting it in his oven. The turkey started at a room temperature of 25°C, and the oven was preheated to 175°C. If Gregory accidentally turns off the oven after he places the turkey inside of it, then what will happen to the turkey? *
A)Thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.
B)Thermal energy will flow from the turkey into the oven and continue to flow until they reach equilibrium at 100°C or the oven is turned off.
C)Thermal energy will flow from the oven into the turkey and continue to flow until the turkey reaches a temperature of 200°C.
D)Thermal energy will flow from the turkey into the oven and continue to flow until the oven reaches a temperature of 200°C.
Answer:
A
Explanation:
The correct answer would be that thermal energy will flow from the oven into the turkey and continue to flow until they reach equilibrium at 100°C or the turkey is removed.
Since there is a difference in the temperature of the two bodies, thermal energy will continue to flow from the body with higher thermal energy to the body with lower thermal energy until an equilibrium is established between the two bodies.
In this case, thermal energy from the oven will continue to flow to the turkey, raising the temperature upward from 25 °C. As the temperature of the turkey is increasing, that of the oven would be decreasing till both the turkey and the oven have the same temperature or when the turkey is removed from the oven.
The correct option is A.

Primary productivity
B
Gross primary productivity
С
Net primary productivity
D
Cellular respiration
Answer:
C. Net Primary productivity
Explanation:
In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.
The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R
Where, R = energy lost via respiration.

What are jupiter's moons?
Io is one of the four largest moons of Jupiter and the fourth largest moon in the solar system. It is named after the mythological character Io from Greek mythology, who was a priestess of Hera and was transformed into a heifer by Zeus to protect her from Hera's jealousy. Io is known for its intense geologic activity, with over 400 active volcanoes and volcanic plumes that can reach heights of over 300 kilometers (190 miles) above the surface. The high levels of volcanic activity are due to tidal forces from Jupiter and its other large moons.
Hence, the correct answer is Io, a figure in Greek mythology, as it was the moon discovered by Galileo Galilei in 1610 and is named after the mythological character.

A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? A-The cell was submerged in a hypertonic solution. B-The cell was submerged in a hypotonic solution. C-The cell was submerged in a pure solution. D-The cell was submerged in an isotonic solution.
Answer:
A
Explanation:
The correct answer would be that the cell was submerged in a hypertonic solution.
A hypertonic solution is a solution with a higher concentration of solutes than that of the cytosol of a cell suspended in it. When a cell is suspended in a hypertonic solution, water moves osmotically from the cytosol to the hypertonic solution. This causes the cytoplasm to collapse and the cell becomes flaccid.
The correct option is A.
Answer:
D. The cell was submerged in a hypertonic solution.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old
Answer:
The age of the rock is 5 million years
Explanation:
Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16
Number of half-lives undergone by the substance to leave behind 1/16 of the original sample
1/16 = (1/2) * (1/2) * (1/2) *(1/2)
Therefore, the substance have decayed 4 times
One half=life = 1.25 million years
Four half-lives = 4 * 1.25 million years = 5 million years
Therefore, the age of the rock is 5 million years

explain how ostriches evolved to survive in their environment.
Answer:
Some scientists believe that there were huge fires and the skies were dark and full of pollution due to a meteor exploding and killing off the dinosaurs, and if it's true that this occurred, the Ostrich evolved to be a land animal due to it being too dangerous in the air for them. The long neck may have developed to help them get food that was higher up which is the same speculation for the Giraffe. To stay on land they had to be stronger, bigger, and faster than they were in flight.

2) What are other potential medical uses?
Answer:
1. A stem cells can be defined as totipotent cells because they have the capacity to self renew themselves.
Spinal cord injury leads to loss of nervous tissue also loss of motor and sensory function, currently there is no such treatment available that can completely repair the spinal cord, but the transplant of stem cells may help in the spinal cord repair.
The stem cells could never replace the nerve cells that died as a result of the injury, stem cells can help the nerve cells to repair.

Why does a carrot in a hypertonic solution of salt water float compared to a carrot in a hypotonic solution of salt water (which sinks)?
Answer:
Cell membranes are permeable to water, and in the absence of a solute on either side of a membrane, water will move one way as easily as it moves the other. If the outside of the membrane contains a solute, such as salt, the solution correspondingly contains fewer water molecules. To restore equilibrium -- the same number of water molecules on both sides of the membrane -- water flows from inside, and the cell shrinks. On the other hand, if the concentration of solute inside the membrane is greater, water flows into the cell and swells it. This is called osmosis.The turgidity, or stiffness, of a carrot depends on the water content of its cells. When the cells are full of water, they grow large and are packed closely together, making the carrot turgid. Conversely, when the cells lose water, they shrink and the carrot shrivels. That's what happens when you put a carrot in salty water and leave it there. When the concentration of water molecules inside the cells matches that outside, the carrot stops shriveling, and when you remove it from the water and taste it, it has a stronger flavor because it contains less water

Deforestation is the permanent destruction of forests in order to make the land available for other uses. This process leads to fewer plants being available to conduct photosynthesis. Which of these is a possible effect of deforestation on the process of cellular respiration?
Answer:
A lesser amount of oxygen will be available for cellular respiration
Explanation:
Deforestation can be defined as the permanent removal of trees in forest areas for other land uses (for example, agriculture use). It is well known that deforestation has a negative effect on natural ecosystems. An important proportion of the oxygen in the air is generated by plants during photosynthesis, and it has been estimated that about 30% of the land photosynthesis is due to tropical forests. Aerobic cellular respiration is a metabolic pathway by which organisms use oxygen to produce energy in the form of ATP. In consequence, deforestation represents a serious problem to sustain cellular respiration, and ultimately to sustain life.
Answer:
Less oxygen is available for use during cellular respiration.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.
Answer:
The pesticide measurements were the dependent variable
Explanation:
According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:
- Select one location to collect water samples in the pond.
- Collect a 5-mL water sample at 8 am for two days.
- Measure the amount of pesticide present in each sample using the same measurement tools
However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.
Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.
