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.

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.

Explanation:
Surface Irrigation involves distributing water over the surface of the soil by allowing water to flow into the farm from irrigation channels.
Sprinkler Irrigation involves use of pressurized nozzles to spray water in a shower on the plants.
Variable flow irrigation involves use of advanced version of sprinkler irrigation. It has a variable-flow control knob on it to vary the output and flow of water. It also ensures uniform water distribution.
Trickle Irrigation involves dripping water onto the soil at very low rates through a system of tiny pipes fitted with outlets called emitters or drippers in order to control the flow of water.
Sub-irrigation involves the use of perforated pipes to apply water below the soil surface in order to raise the water-table near the plant root zone as well as to remove excess water.

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.
Explanation:
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

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.

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

1) How might stem cells be a solution to paralysis caused by spinal injuries? The stem
cells could replace the nerve cells that have died as a result of the injury.
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.
2.Other medical uses are:
To repair the damaged organs or tissues Correct the genetic defects safely testing of new drug.What are the two leading causes of CO2 being in the atmosphere?
