Answer:

1.Plasma membrane

The plasma membrane surrounds the cell to create a barrier between the cytosol and the extracellular matrix. Plasma membranes also enclose lumens of some cellular organelles.

2.Endoplasmic reticulum

The endoplasmic reticulum (ER) is a large network of membranes responsible for the production of proteins, metabolism and transportation of lipids, and detoxification of poisons. There are two types of endoplasmic reticulum with separate functions: smooth endoplasmic reticulum and rough endoplasmic reticulum. The presence or absence of ribosomes in the ER’s plasma membrane determines whether it is classified as smooth or rough ER.

3.Golgi apparatus

The Golgi apparatus appears as a series of flattened, membranous sacs, or cisternae, that resemble a stack of pancakes just off the rough endoplasmic reticulum. It receives vesicles containing proteins recently produced by the rER. The Golgi apparatus can be compared to a warehouse or post office for newly formed proteins. Here the proteins are further modified, packaged, and sent off to their final destinations in the cell or body.

Por qué algunos fosiles son similares a especies actuales
Blizzard [7]

Answer:

Explanation:

La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.

When does cellular respiration occur? are there any situations where living cells are not respiring?
ivann1987 [24]
Cellular respiration occurs in the mitochondria, the double membrane organelle. It occurs when the cells need energy, storage molecules like glycogen are rapidly broken down from being a polysaccharide to its monomer units which undergo reactions once transported to the cells requiring energy and broken down to release its energy.

Yes, there is a situation where living cells are not respiring. For example in the microbial cell that lives in anaerobic environments in specific environments will use fermentation instead of respiration to produce ATP. The example of this is the yeast cells in beer mash.

Which type of information is pseudoscience based on?
OlgaM077 [116]

Answer:

Unsupported claims

Explanation:

Pseudoscience is kind of a <em>fake </em>science. it uses scientifical terms to trick people into thinking it actually <em>is </em>science. It uses words like "quantum" in a sentence such as "Buy this quantum phone charger for your phone to charge 2x the normal speed!" Since it has the "quantum" in it, some people do actually think it's scientific, and fall for that ad.

So, the answer is unsupported claims because those claims such as "Drinking milk and eating mango at the same time lead you to death" are fake beliefs that don't have any scientifical evidence.
