III. Inexpensive compared to other resources
A. I only
B.II only
C. I and II only
D. I, II, and III
Answer:
C. I and II only
Explanation:
i took the test and got it right
Photovoltaic cells and hydrogen fuels are inexpensive compared to other resources as well as they produce no pollutants to the surroundings. They components are abundant in nature as well. Hence all the options are correct.
What is photovoltaic cell ?A photovoltaic cell uses solar energy and converts the light energy to electrical energy. They are working with the principle of photoelectric effect. The solar energy is abundant to use and it is relatively less expensive to design the photovoltaic cells.
Fuel cells are using hydrogen as fuel. Hydrogen is abundant in the universe and is most efficient than all other fuels sources. Fuels cells involve the reaction of hydrogen and oxygen forming and water and not any other compounds are formed.
Both photovoltaic cells and hydrogen fuels are eco-friendly in the sense that they does not produce any pollutants to the atmosphere. Therefore, all the given are advantages of photovoltaic cells and hydrogen fuel.

Why is Biodiversity considered Earth's own “ Safety net”?
Answer:
Explanation:
Biodiversity allows for everything to exist. All types of animals, plants, etc. work and contribute in different ways, the actions that every species makes contribute to the larger ecosystem which allows for plants to grow, food to exist, other species to thrive, the atmosphere to exist, etc. All of these side effects create a system that allows Earth to maintain a habitable state and prevents it from becoming a dry and bare planet that cannot sustain life.

Using at least three sentences, describe the process of weathering, and explain how it can happen physically or
chemically?
Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock

Hydrosphere
Geosphere
Atmosphere
Biosphere
The matching of each example with the system where it belongs is as follows:
Hydrosphere: Pond, Lake, etc. Geosphere: Mountain range. Atmosphere: Gaseous nitrogen. Biosphere: Microorganisms and Coastal vegetation. What is an Atmosphere?An atmosphere may be characterized as a type of layer that significantly of numerous gases that surrounds any celestial planet like earth. The atmosphere of the earth is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
The atmosphere of Earth is significantly composed of gaseous nitrogen. While the biosphere majorly consists of all sorts of living organisms like microorganisms and coastal vegetation. The hydrosphere deals with something that is related to the presence of water, i.e. ponds, lakes, rivers, seas, etc.
Therefore, the matching of each example with the system where it belongs is well mentioned above.

Si durante la division de las celulas de la raiz de una planta se aplica una sustancia x que destruye el complwjo de golgi de estas celulas¿cual sera el efecto esperado en dicho tejido
Answer:
cada célula tendrá dos núcleos
Explanation:
El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.

the process of elimination of nitrogenous waste from the body
Answer:
Excretion
Explanation:
The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. When cells break down proteins, they produce nitrogenous wastes, like urea. The excretory system serves to remove these nitrogenous waste products, as well as excess salts and water, from the body.
Describe the path of a nitrogen atom through four parts of the nitrogen cycle. Be sure to explain the processes involved in the transfers. Note when a form of nitrogen is available to plants.
Answer: One of the ways the path of a nitrogen atom begins is as a part of an ammonium ion. A plant takes up the ion and uses it to make an organic molecule through assimilation. The organic molecule falls back to the ground as part of a leaf. The leaf is decomposed by bacteria, and it is converted back to ammonium by ammonification. The ammonium ion is then converted to nitrite by nitrifying bacteria through nitrification.
Explanation: That's what popped up after I hit submit so that's the answer hope this hepls.
Answer:
A nitrogen atom can start its journey as part of an ammonium ion, for example. Through assimilation, a plant absorbs the ion and uses it to create an organic molecule. As part of a leaf, the organic molecule returns to the earth. Bacteria breakdown the leaf, which is then turned back to ammonium by ammonification. Through nitrification, the ammonium ion is transformed to nitrite by nitrifying bacteria.

Use scientific reasoning and the food web to explain why, in general, it makes sense that the lion population is taking longer to recover than the herbivore populations.
Answer:
Explanation:
Herbivores are able to come back easily when they are search for food because their are more than enough food for them to prey on while in lion population, their main feed also take longer period to be produced since they also feed on animal that take time to give birth such as zebras, so they go for other smaller organisms such as waterbucks which take them more time to be completely feeds on to gain required energy.

Two groups of fifth grades were tested to compare their speed at solving long division problems. One group had calculators and the other did not. Independent variable, dependent variable, controlled variable
Answer:
Independent variable: CALCULATOR
dependent variable: SPEED AT SOLVING LONG DIVISION PROBLEMS
controlled variable: SAME GRADES, SAME PROBLEM
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the independent variable is the CALCULATOR, which was changed in the experiment.
Dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the SPEED AT SOLVING LONG DIVISION PROBLEMS.
Controlled variable or constants are variables that are kept unchanged for all groups throughout the experiment. In this experiment, the controlled variables are: SAME GRADES, SAME DIVISION PROBLEM
