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).

3. Why is it sometimes necessary to use a model that is "not to scale"?
joja [24]
My answer: Because the actual thing you might be modelling might be too small or large to replicate, (for example you cannot draw a plant cell TO SCALE because it’s way too small to see with a bare eye).
And if the item is too big, you won’t be able to fit it in a small space; if you were to draw it or create it in 3D.

I hope this helps!

<h2>Operational </h2>

Explanation:

The operational definition is the description of a specific process, or set of validation tests, accessible to more persons than the definer (i.e., said to be publicly accessible), where it can be repeatedly measured or tested

Operational definitions are also used to define system states or (nonspecific) physical objects by the description of a specific process of preparation which can be repeated

For example in the given example experimenter is using the case of hitting a punching bag to measure the level of aggression in someone

Masja [62]
<span>Active transport works to conserve homeostasis. When cells are doing something they typically receive a signal causing channels to open, which in turn lets in a flood of molecules down their chemical gradients. Hope this answers the question.</span>
