Answer:
C) La célula es la unidad de evolución de los seres vivos.
Explanation:
La teoría celular fue formulada por Schleiden y Schwann en 1837 a partir de observaciones propias y de información citológica relacionada con la estructura y la función de las células obtenida muchos años anteriores a ellos, especialmente a partir de los aportes de 1-Anton Van Leewenhoek, quien identificó microrganismos vivos mediante sus observaciones con un microscopio, y 2-Robert Hooke, quien observó celdas (de allí el nombre de células) también bajo el microscopio. Schleiden y Schwann postularon que la célula debería ser la unidad estructural y funcional en los seres vivos, la cual debería ser capaz de mantener de modo independiente el estado vital. Posteriormente, en 1855, Virchow aportó una conclusión fundamental: todas las célula derivan de la replicación (división) de células preexistentes. Los virus se consideran una excepción a la teoría celular porque ellos son considerados organismos vivos (aunque esta consideración está sujeta a debate), los cuales poseen un nivel estructural y de organización menor al nivel de una célula. Respecto a este punto, cabe aclarar que los virus son parásitos intracelulares los cuales derivan (descienden evolutivamente) de organismos celulares y por lo tanto es posible asumir a sus orígenes como subproductos de los genomas de las células (es decir, de organismos celulares).

What's the difference between cytoplasm & protoplasm?
Answer:
Cytoplasm-everything contained within the cell membrane except the nucleus.
Protoplasm-includes everything in the cytoplasm plus the nucleus.
Explanation:
Hope this is helps :)
Cytoplasm
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is included by Protoplasmprotoplasm
protoplasm is the colourless material comprising the living part of a cell.It include the cytoplasm, nucleus, and other organelles.In Asexual reproduction an organism produces
Answer:
Identical offspring
Explanation:
Because it's not like sexual reproducton where the parents split their DNA so the offspring gets half of each of the parents DNA. Also in asexual reproduction, there is only one parent, therefore it is an identical offspring
Answer:
I think the Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.
Hope this help you!:)

The graph below shows the populations of two species from January 2010 to June 2011. One species is native to the ecosystem, while the other is a new species that was recently introduced to the ecosystem.
What is the most likely explanation for the changes to the populations of species A and species B?
Species A is a native species that preys on species B.
Species B is an invasive species that altered the balance of the ecosystem shown.
Species A is an invasive species that cannot compete with the native species in the habitat.
Species B is a native species that is able to adapt to a sudden climate change while species A cannot.
Answer:
Species B is an invasive species that altered the balance of the ecosystem shown.
Explanation
An invasive species is an introduced organism that negatively alters its new environment

After using ammonia in an experiment, Artie had some left over. What should Artie do with the leftover ammonia?
Accordingly, once you diluted the ammonia completely, it is suitable for disposal. You can pour the aqua ammonia down the kitchen sink, or flush it down your toilet. However, beware if you have a septic drainage system, the solution will proceed to mix with the water underground and pollute it.

How does gravity affects the Earth's orbit around the Sun?
Answer:
The Sun's gravitational force is like the tetherball rope, in that it constantly pulls Earth toward it. ... This means that the planet neither flies out into space nor falls into the Sun. Instead, it travels in a nearly circular motion around the Sun, creating an orbit
What is the name of the bond that is formed between a glycerol and a fatty acid
Explanation:
In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.
How are a good chain and a good web different
Answer:
Explanation:
A food chain only follows one path of what food animals eat. A food web consists of many food chains that show how plants and animals are connected. In conclusions, a food chain focuses on a certain animal or their path and they are linear. Food webs are more complex which show how the ecosystem works together to create a balance.
Answer:
A food chain goes in one drection and a food web is more complex and is a whole system of connected food chains.
Explanation:
Where does most of the mass of trees come from
Answer:
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.

describe the greenhouse effect
[tex] \huge\mathfrak \pink{answer}[/tex]
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
