Answer:

Yes

Explanation:

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.

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.

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.

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.

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.

Answer:

The Answer Is A.

Explanation:

If They Can Be Used For Cleaning Up Mining Waste And For Sewage Treatment, That Makes Them A Good Thing. So It Wouldn't Be A Concern. Hope This Helps.

Genetically engineered bacteria cells can be used to clean up mining waste and for sewage treatment, which is not an ethical concern raised by genetic engineering. So, the correct option is A.

Genetic engineering may be defined as a process that involves the manipulation of the genetic material of organisms with help of lab-based technologies.

Bacterial species produced by genetic engineering used in cleaning up mining waste and sewage treatment benefit the atmosphere by reducing the level of waste and toxic compounds from suuroundings. So, it is not a matter of ethical concern.

Therefore, the correct option for this question is A.

Answer:

A. high tide (A, C)

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.

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.

Explanation:

Mark me brainliest please

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".

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).

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.

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.
