A grass starts with 30,000 kJ of energy. How much energy would a cheetah acquire after it ate a zebra that consumed the grass?
30 kJ
300 kJ
3,000 kJ
30,000 kJ
Answer:
it is 300kj
Explanation:
The energy that will be acquired by the cheetah when it consumes the zebra is 30,000 kJ.
Law of conservation of energy
The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.
The energy of the grass will be transferred to the zebra when the zebra consumes the grass. Also the total energy of the zebra will be transferred to the cheetah when it consumes the zebra.
Thus, the energy that will be acquired by the cheetah when it consumes the zebra is 30,000 kJ.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.
Answer:
Active transport.
Explanation:
The kidney uses active transport to move these substances from the nephron to the renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the renal vein.

Contrast the contraction of the a disease by the environmental, heredity/genetic and pathogenic pathways.
Answer:
Explanation:
Contraction of a disease by the environment, the environment is said to influence something certain traits either by amplifying them or prevent them from being expressed. Some disease tends to strive in environment that is favorable while some disease don't find expression where the environment is not conducive even though they are presents in the gene of the individual. Environment could include family, area where the individual lives, food, peer
While Contraction of disease that are heredity/genetic and having pathogenic pathways is high this is because any disease that is hereditary can be passed to successive generation through the inheritance of such gene from the parents this increase the likelihood of reoccurrence of such disease in a family where the parents has it.
A student is investigating mechanical and electromagnetic waves. She is creating a list of questions to include in her investigation about the properties of each type of wave. Which is NOT a question that she can ask that will allow her to learn about the properties of both mechanical and electromagnetic waves?
A
What is the amplitude of the wave?
B
What is the frequency of the wave?
C
What is the wavelength of the wave?
D
What is the wave speed in a vacuum?
Answer:
It would be B
Explanation:
I am sorry if it is wrong
"What is the frequency of wave?" is not a question that she can ask. Thus, the correct option is B.
What is the frequency of wave?Wave frequency is the number of waves which pass through a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz). One hertz (Hz) equals 1 wave passing a fixed point in the time period of 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same magnitude of amplitude.
The equation used for determination of wave frequency (f) will be:
f = v/λ
where λ is the wavelength in meters and v is the speed of the wave in m/s.
Therefore, the correct option is B.

Explanation:
Two distinct bands appear in a single lane at the completion of an SDS-PAGE analysis of an unknown protein. Select one: a. These bands represent two subunits of a homodimer. b. Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.
Answer:
b. Each band represents a different-sized subunit of a multimeric protein.
Explanation:
SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.
The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.
SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be. The speed of displacement in the electromagnetic field is inversely proportional to the protein size.

a student wants to hold the sides of a garbage bag to the sides of her trash can she tries round rectangular and square shaped magnets but the magnets do not stick to the sides of the trash can, what is a reason the magnets do not stick to the sides of the trash can ?
Answer:
If the insulating material covered around the can.
Explanation:
If the can is covered with thick layer of insulating material then it can't be attracted by the magnet because there is a gap between magnet and metal. Can is a metal which is attracted by the magnets just like iron and copper etc. If there is no insulating material between magnet and can, then it must be attracted by the magnet so that's why we can say that insulating material is responsible for the no attachment of magnet to the can.

Thomas Malthus was an economist who influenced Darwin's developing theory of evolution. Malthus observed that the birthrate among humans exceeded the death rate. If this trend continued, soon there would not be enough resources to support human population growth. He reasoned that the only things capable of stopping human population growth were famine, disease, and war. Darwin applied this thinking to animals and plants as well, noting that far more offspring were produced than survived to a reproductive age. 2. How did Charles Darwin build on the work of Thomas Malthus to develop the idea of evolution by natural selection
Answer:
The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.
Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

Photosynthesis captures and uses energy from the Sun for daily activities.
Photosynthesis captures and stores energy from the Sun.
Photosynthesis requires carbon dioxide and water.
Photosynthesis stores the energy from the Sun in molecules of sugar.
Answer:
photosynthesis captures and uses energy from the sun for daily activities
Explanation:
In the carbon cycle, atmospheric carbon dioxide is converted into organic material by which process? a) transpiration b) cellular respiration c) decomposition d) photosynthesis
Answer:
The correct answer is d) photosynthesis
Explanation:
Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.

Answer:
quantitative data
"quantitative" refers to the amount of something, so if it has something to do with numbers, It's quantitative.
There were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.
What quantitative and qualitative data are there?There are both types of data, such as the quantitative data, in which the quantity can be measured, such as the 12 elephants and the 141 beats, and the qualitative data, which can't be measured but is widely seen in the genetics, such as the coat color of the animals, the skin color of the human, etc.
Hence, there were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

Which statement describes both a positive impact and a negative impact associated with the effects of nitrogen-enhanced fertilizers?
They increase polluted runoff and damage drinking water.
They increase plant growth and damage drinking water.
They increase denitrifying bacteria and increase plant growth.
They increase both limiting resources and denitrifying bacteria.
Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body
