Answer:

Explanation:

The earth turns on its axis every day; it orbits the sun, just like all the other planets in our Solar System. When viewed from space, it turns counter-clockwise.

Because it rotates around the earth at the exact same speed as it rotates around its own axis, so that the same side of the moon is constantly facing the surface of the earth.

Tilt of the earth on its axis is responsible for season formation. The amount of sunlight obtained by various regions on earth surface is regulated by tilt. The places of earth that are facing the Sun and get direct sunlight experiences summers while the others which are facing away from the Sun experience winter season.

Day and night are caused by Earth's revolution on its axis.<br> T or f
xenn [34]

Answer:

i belive it is true

Explanation:

We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it. It takes 24 hours for the world to turn all the way around, and we call this a day.

Which of the following is continually passed from one enzyme to the next during the Electron Transport Chain?
AVprozaik [17]

The correct answer is electrons.  

Electron transport chain refers to an array of complexes, which mediates electrons from electron donors to electron acceptors through redox reactions, and combines the transfer of electrons with the transfer of protons through a membrane.  

This produces an electrochemical proton gradient, which instigates the production of ATP. The ultimate electron acceptor in the electron transport chain is oxygen in aerobic respiration and sulfate in anaerobic respiration.

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mi
MaRussiya [10]

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.
