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.

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.

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

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:

Compare and contrast characteristics and use his own diodes and triodes
Answer:
Comparison of characteristics and use of diodes and triodes is given below:
Diode and triodes both are electrical components but diode allows the flow of current in only one direction while triode has three electrodes.Diode consists of two terminal (anode and cathode) while Triodes have three terminals (cathode, anode, and grid). A diode is an electrical component used to control voltage while triode is a current controlled device. Diodes used in modern electronics such as LED while triodes are used in RF heating systems.Answer:
1. Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
2. Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.

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.

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

Trickle Irrigation involves use of emitters to control the flow of water
Sub-irrigation involves the use of perforated pipes
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.
