It is the outermost layer in the animal cell and is found just inside the cell wall in the plantcell.Answer:
The Cell Membrane is the outer layer of a cell that separates it from the In both plant and animal cells, the cell membrane is found.
In an animal cell, it is located just within the cell wall, while in a plant cell, it is located just inside the cell wall. Cholesterol is present in the membrane of animal cells, but not in the membrane of plant cells.
Explanation:
An animal cell's outermost layer is the cell membrane.
It is found immediately under the outermost cell wall layer in plant cells.
It is made up of the following components:
a bilayer of phospholipids.Membrane proteins are proteins that are found in the membrane ofChannels in the membraneCholesterol.Receptors that send forth signals.During cell signaling, lipid rafts are used to attach intracellular proteins.It has a fluid or mosaic texture, and the molecules in the layer can move around.

Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the molecule has a partial negative charge and the oxygen end has a partial positive charge. B. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. C. Both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.
Answer:
option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
Justification:
The electronegativity of an element accounts for its relative ability to attract electrons.
Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.
Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.

Fenotipo: Parte de la información genética que se manifiesta en el individuo.
Puede definirse como la forma de expresión de uno o mas caracteres por parte del individuo. Muchos factores externos al individuo pueden moldear el fenotipo para hacerlo mas apto al medio. Asimismo el fenotypo y el ambiente actuan en forma conjunta para determinar el destino de los genes en el espacio y en el tiempo.
Cromosoma: Conjunto de ADN con forma de bastón o de X.
Todas las unidades genéticas que llevan información de herencia y que regulan los procesos celulares. Pueden distinguirse claramente durante la división cellar, durante la cual los cromosomas se condensan. La molécula de ADN en eucariotas es lineal y larga, y se asocia a proteinas llamadas histonas y a otras que no son histonas, formando la cromatina. Anted de la division celular la cromatina es laxa, y durante la división se condensa y se define en cromosomas. Cada cromosoma porta diferentes genes.
Alelo: Variante que determina un caracter (dominante or recesivo)
Los alelos son las distintas formas en las que un gen puede expresarse. Son las formas alternativas de un mismo gen. Resultan d la mutación de un gen original. Estas formas codifican para la misma caracteristica, pero exresando un fenotipo distinto al original.

6. What is the relationship between genes and alleles?
Answer:
A gene is a unit of hereditary information. Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. So, what it is the difference between a gene and an allele? The short answer is that an allele is a variant form of a gene.

what are the mechanisms that halophiles typically employ to grow in habitats with high concentrations of salt
Answer:
Synthesis Of Osmoprotectants
Explanation:
One Mechanism Halophiles use to survive in high concentrations of salt is the Synthesis Of Osmoprotectants, which are also known as compatible solutes. These work by balancing the internal osmotic pressure with the external osmotic pressure, making the two solutions isotonic, or close to it.

mostly escaped Earth's atmosphere due to it is light mass
Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
Answer:
Nitrogen - formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor - released into the atmosphere during volcanic eruptions
helium - mostly escaped Earth's atmosphere due to it is light mass.

Explanation:
In the electron transport chain, which structure forms a channel in the inner membrane of the mitochondria and adds phosphate to ADP
Answer: ATP synthase
Explanation:
The ATP synthase complex is an enzyme located in the inner membrane of the mitochondrion that catalyzes the synthesis of ATP from ADP, a phosphate group and energy supplied by a proton (H+) flux. This ATP synthesis occurs during cellular respiration, which is a set of biochemical reactions by which certain organic compounds are completely degraded by oxidation to inorganic substances. This process provides usable energy to the cell in the form of ATP.
During cellular respiration, ATP synthesis is termed oxidative phosphorylation and the proton flux takes place between the intermembrane space and the mitochondrial matrix. ATP synthase produces ATP when protons flow through it. The proton flow creates a pH gradient and an electrochemical gradient. This proton gradient is used by ATP synthase to form ATP via oxidative phosphorylation. ATP synthase acts as an ion channel that "returns" protons to the mitochondrial matrix. During this return, the Gibbs free energy produced during the generation of the oxidized forms of electron transporters is released. This energy is utilized for ATP synthesis. It must then be considered that the electron transport chain and oxidative phosphorylation are coupled by the proton gradient.
