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.

HELP!What are the roles of and what happens to chromosomes, centrioles, centromeres, spindle fibers, nucleus and cell membrane during mitosis.
Answer:
Perhaps the most amazing thing about mitosis is its precision, a feature that has intrigued biologists since Walther Flemming first described chromosomes in the late 1800s (Paweletz, 2001). Although Flemming was able to correctly deduce the sequence of events in mitosis, this sequence could not be experimentally verified for several decades, until advances in light microscopy made it possible to observe chromosome movements in living cells. Researchers now know that mitosis is a highly regulated process involving hundreds of different cellular proteins. The dynamic nature of mitosis is best appreciated when this process is viewed in living cells.

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.

Explain why the chemical equation for photosynthesis is a simplified representation of the process. How is the equation accurate? How is it inaccurate?
Answer:
The equation shows the general reactants and products of the process. However, it does not show intermediate steps. For example, carbon dioxide and water do not actually react with each other.
Explanation:
The equation is representing the general reactants and products of the process. But, it does not express the intermediate steps. For example, carbon dioxide and water do not actually react with each other.
What is photosynthesis reaction?The procedures by which chlorophyll bearing organisms and certain other microbes transforms sunlight to chemical energy is renowned as photosynthesis.
Light energy is grasped and utilized by green plants in the process of photosynthesis to efficiently convert, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Plants grab these carbon dioxide as well as water from either the environment or soil during photosynthesis.
Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
The equation represents the process's broad sense reactants and products. It does not, however, convey the intermediate steps. Carbon dioxide and water, for example, don't really actually react with each other.
Thus, that's why the equation is perhaps not accurate.

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.

Thermoses work because they minimize which kinds of heat transfer?
A.Conduction and convection
B. Conduction and radiation
С. Convection and radlation
D. Conduction, convection, and radiation
Answer:
B or C
Explanation:
I read about this awhile ago just forgot if it was ethier conduction or convection
The thermal heat energy transfers through various modes. Thermoses work because they minimize conduction and radiation transfer of heat. Thus, option B is correct.
What is heat transfer?Heat transfer has been the process that moves the heat from higher temperature towards the area of lower temperature. Conduction, convection, and radiations are the three modes of heat energy transfer.
In conduction, the heat flows from one body to another when they are in contact, and in radiation the heat flows in the waveform that does not need any direct contact. It needs an indirect medium to transfer the heat from high to lower temperatures. Thermoses do not show convection as it keeps the temperature constant.
Therefore, option B. thermoses use conduction and radiation.

Select one:
a. 23, 23, 23
b. 46, 23, 23
c. 46, 12, 12
d. 46, 46, 46
Answer: B is the answer
Following mitosis, the daughter cells would each have a total of 46
chromosomes.
After meiosis I, the two daughter cells would have 23 chromosomes, and
after meiosis II it will still remain as 23 chromosomes.
Mitosis is a type of cell division that involves the production of identical
daughter cells. The daughter cells usually contain 46 chromosomes with all
the parent traits present.
Meiosis is a type of cell division which produces sex cells and for
reproduction. It involves generating unique daughter cells which is gotten by halving the 46 chromosomes to become 23 chromosomes.

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.
