Why does sodium and potassium ions need a protein pump to pass through the cell membrane?
A. The ions have a charge and cannot pass directly through the cell membrane.
B. The ions are moving against the concentration gradient.
C. Energy is needed to move the ions.
D. All of the above.
Cell membrane have been the selective membrane that allows transportation. Sodium and potassium ions need a protein pump as they are charged particles that move against the gradient and need energy. Thus, option D is correct.
What is active transport?Active transport has been the way to move ions and molecules inside and outside the cell membrane. This system of transportation requires energy as the ions move from low concentration regions to the region of the higher electrochemical area.
The sodium and potassium pump needs proteins and energy to move the ions as the inside of the cell is rich in potassium and the exterior is rich in sodium ions. The charged ions moving against the concentration cannot enter the cell without energy and protein pumps.
Therefore, option D. all of the above statements are correct.

Desde captar el estimulo hasta efectuar una respuesta, la secuencia que sigue en el impulso nervioso es?
Answer:
creación de un potencial de acción (despolarización), redistribución de iones a través del soma y finalmente repolarización (estado de reposo)
Explanation:
Las neuronas son células nerviosas capaces de transmitir impulsos en forma de corriente eléctrica. Una neurona está compuesta por dendritas, el soma o cuerpo celular y el axón. Durante la transmisión del impulso nervioso, el estímulo es en primer lugar recibido por las dendritas, recorre el soma y termina en el axón. El impulso nervioso se transmite a través de la neurona mediante un proceso de despolarización. Primero, se produce un aumento de la carga eléctrica en el interior de la membrana neuronal debido al aumento de iones de sodio en el interior celular. A continuación, se produce la redistribución de iones dentro del soma, con lo cual la señal se va transmitiendo a lo largo de la neurona. Finalmente, cuando el impulso ha terminado de recorrer el axón, se produce la repolarización o estado de reposo, donde se produce el restablecimiento de las concentraciones iniciales de iones y la neurona vuelve a su estado inicial.
Santos and Lüderitz are the same distance from the equator, and both cities are near the ocean. The air temperature in Lüderitz is colder than the air temperature in Santos. What causes the air temperature in these places to be different? Explain what causes the difference as completely as you can.
Answer:
The Ocean Currents.
Explanation:
if you look at a current map, you'll see warm currents near Sanots and cold ones near Lüderitz. Therefore, the air in Sanots is a lot warmer and the air in Lüderitz is colder.
The phenomenon of the ocean current is responsible for this deviation of air temperature between two places.
What do you mean by Air temperature?Air temperature may be defined as the temperature of the surrounding air of organisms including humans.
The ocean water captures the heat from the sunlight and increases the temperature of the ocean. This heat is then entranced through ocean circulation and increases the temperature of the air as well as the atmosphere.
The air temperature in Luderitz is colder because the ocean of this region receives less sunlight in low intensity which results in less heat captured by the ocean and makes the air a little bit colder than that of Santos oceans.
Therefore, it is well described above.

Cellular respiration is the process of using the chemical energy stored in sugars. The reaction is the mirror image of photosynthesis: glucose, + oxygen yields carbon dioxide +water. Like all living things, plants go through cellular respiration to obtain energy for growth and reproduction.
What type of cells do you find homologous chromosomes?
"Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid. The matched pairs of chromosomes in a diploid organism are called homologous chromosomes."
how to do this question plz
Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".

why is this conversion of energy from one molecule to another necessary for all cells?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the energy conversion
=> ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell.
=> When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

In a DNA molecule, the number of adenine bases equals the number
of thymine bases because thymine on one strand bonds to adenine
on the other strand.
True or false
It is TRUE that in a DNA molecule, the number of adenine bases equals the number of thymine bases because thymine on one strand bonds to adenine on the other strand.
DNA COMPOSITION:
DNA is composed of nucleotides subunits. There are four nucleotides present in the DNA molecule namely: Adenine, Cytosine, Guanine and Thymine. Adenine and Thymine hydrogen bond together while Cytosine and Guanine hydrogen bond together i.e. A-T, G-C. According to Chargaff rule, the amount of adenine bases equals the amount of thymine bases while the amount of guanine bases equals the amount of cytosine bases. This is because adenine on one strand of DNA bonds to thymine on the other strand of DNA, hence, they must be in the same amount.Learn more: https://brainly.com/question/12683542?referrer=searchResults

Explanation:
High tides on points A & C occur when the moon, the Earth, and the Sun are all lined up.
SUN -----<<< EARTH >>> ---
----MOON
( as accurate as it can be in 2D)
As you can see, they are all in a straight line. The gravity of both the moon and the Sun are combined to output the greatest amount of gravitational force as possible; creating high tides on the 2 sides of the Earth. Points A & C represent these two sides and are therefore the answer.

Digestive enzymes are most active in an environment with a pH of 7. B. Enzymes operate most efficiently within a certain range of temperatures. C. Enzymes are only able to operate in acidic environments. D. Each enzyme operates best within a certain pH range.
Answer:

Explanation:
Each enzyme operates best within a certain pH range.
Digestive enzymes are most active in an environment with a pH of 7 is the conclusions can be drawn from this graph.
What is enzymes?Enzymes are referred to as proteins which act as biological catalysts. Catalysts enhance the chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
Each enzyme works within quite a small pH range. There is a pH at which its activity is greatest (the optimal 7 pH) because changes in pH can make and break intra and intermolecular bonds, changing the shape of the enzyme and, therefore, its effectiveness.
