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.

Answers

I believe it is D
I’m not sure
Sorry if it is wrong

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.

A bird that can easily out complete other birds for its food and that can produce many eggs has high what?

Answers

Answer:

Fitness or aptitude

Explanation:

Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.

Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.

Members of different species do not produce offspring due to:
A) Behavioral Speciation (differing mating rituals)
B) Temporal Speciation (varying breeding times)
C) Mechanical Speciation (gamete incompatibility)
D) any of these
(Please Answer Fast)

Answers

A is the answer. I believe, although I’m not 100% sure

Answer:

Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation. These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

Desde captar el estimulo hasta efectuar una respuesta, la secuencia que sigue en el impulso nervioso es?

Answers

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.

How do T-cells help with destroying viruses?

Answers

They secrete chemical messages known as cytokines to stimulate the non-specific immune response to continue, to strengthen and to boost appropriate specific responses.

Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.

Enzymes are only able to operate in acidic environments. D. Each enzyme operates best within a certain pH range.

Answers

Answer:

A

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.

the effects of sunlight on the aquatic life inhabiting the Amazon River. The center of all aquatic life in the Amazon is located in The Amazon Basin, the sun makes sure that all fish and plant life can sustain life.

The sunlight affects the aquatic species that lives in the Amazon River. The Amazon Basin is the epicenter of all aquatic life in the Amazon, where the sun ensures that all fish and plant life may survive.

What is Amazon Basin?

The region of South America that the Amazon River and its tributaries drain is known as the Amazon basin. Approximately 6,300,000 km2, or 35.5 percent of South America, is covered by the Amazon river basin.

The Amazon basin not only contains the world's largest remaining tropical rainforest, it also harbours at least 10% of the known biodiversity, including endemic and threatened species of plants and animals, and its river contributes 15–16% of all river flow into the oceans.

The aquatic animals that inhabit the Amazon River are impacted by sunlight. All aquatic life in the Amazon is concentrated in the Amazon Basin, where the sun ensures the survival of all fish and plant life.

Thus, this is the chief effect of sunlight on the aquatic life inhabiting amazon river.
