Answer:

The electron transport chain stops, stopping the citric acid cycle

Explanation:

Aerobic organisms are those that need the environment in which they live to have the presence of oxygen in order for them to obtain energy. These organisms perform aerobic cellular respiration and are mostly eukaryotic and multicellular sevens.

As previously said, these beings perform aerobic cellular respiration and not fermentation (occurs without the presence of oxygen), if for some reason, an aerobic organism is placed in an oxygen-free environment, cellular respiration will be compromised, because electron transport chain will stop, interrupting the citric acid cycle

Which of the following statements best explains how elements can be distinguished from molecules and compounds?
Aleks [24]

Answer: Option (b) is the correct answer.

Explanation:

A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.

For example, MgSO_{4} is a compound and elements are present in 1:4 ratio.

A compound can be divided into its constituent or simpler substances.

On the other hand, a molecule is defined as a specie that contains same type of elements.

For example, O_{2} is an oxygen molecule.

And, an element is defined as a substance which is made up of only one type of atoms. An element can never be broken down into its constituent particles.

For example, a piece of lithium metal will contain atoms of lithium only.

Thus, we can conclude that the statement elements are made up of one kind of atom best explains how elements can be distinguished from molecules and compounds.

Elabora una hipótesis de: Los cometas habrían contribuido a la Tierra con moléculas orgánicas, como aminoácidos, hidrocarburos y
RUDIKE [14]

Answer:

Hipótesis: la vida está distribuida por todo el universo debido al trasporte de moléculas orgánicas a través de cometas interestelares 

Explanation:

En ciencia, una hipótesis es una explicación posible de una pregunta sobre algún fenómeno específico del mundo natural, la cual es corroborada (o refutada) a través de la aplicación del método científico. A través de técnicas de espectrometría, las cuales son capaces de medir con exactitud los espectros de absorción y de emisión de la luz de determinadas sustancias químicas, los científicos recientemente han determinado inequívocamente que los cometas pueden transportan concentraciones significativas de materia orgánica, es decir, aminoácidos y bases nitrogenadas como las que forman los bloques de construcción del ADN y ARN. En consecuencia, este tipo de observación puede llevar a plantear diferentes preguntas relacionadas al origen de la vida tales como, por ejemplo: ¿ la vida se originó en la Tierra a partir de la combinación de materia orgánica de origen extraterrestre?, o bien ¿la vida se encuentra distribuida en todo el universo gracias a cometas interestelares?. La 'panspermia' es una hipótesis que propone la existencia de vida esparcida por todo el Universo. Esta hipótesis está basada en la existencia de microrganismos extremófilos como aquellos que se encuentran en condiciones extremas de temperaturas, planteando que dichas formas de vida habrían quedado atrapadas en cometas los cuales habrían sido expulsados ​​al espacio como consecuencia de colisiones entre planetas que albergan vida.

a population ecologist determines the number of a oak trees per square unit in a forest. what is he trying to infer by doing so?
elixir [45]
The population ecologist is trying to determine the density of the oak trees in a forest. It is a part of the job of a ecologist. By detecting the density of the oak trees, an ecologist can easily determine whether the density of the oak trees are decreasing or increasing with time and what are the steps that need to be taken to keep the balance.

Drag each label to the correct location on the map.
Sophie [7]

The given question is incomplete as it lacks the map which is important, however the correct answer is attached:

Answer:

The correct answer is -

Top box (green area) - moderate rain,

Middle box (sky blue area) - light rain, and

Bottom box (red area) - heavy rain.

Explanation:

As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.

On the basis of these it we can label all three boxes as per their rainfall amount that is,

Top box (green area) - moderate rain,

Middle box (sky blue area) - light rain, and

Bottom box (red area) - heavy rain.
