Los animales toman del medio los materiales necesarios para sus actividades vitales. Estas funciones la realizan: A. El aparato circulatorio. B. El aparato circulatorio, digestivo y respiratorio. C. El aparato respiratorio. D. El aparato respiratorio y circulatorio.

Answers

Answer 1

Answer:

C. El sistema respiratorio.

Explicación:

El sistema respiratorio es un tipo de sistema en el que los animales toman del medio ambiente los materiales necesarios para sus actividades vitales. Los pulmones son el órgano principal del sistema respiratorio en el que el gas de oxígeno entra al cuerpo y se almacena en los pulmones a través de la inhalación. La hemoglobina que extrae el gas de dióxido de carbono de la célula lo desecha en los pulmones y carga el oxígeno necesario para el proceso de respiración. El dióxido de carbono se elimina de los pulmones mediante la exhalación.

How is oxygen carried from your lungs into all of your cells for cellular respiration?

1. It slowly diffuses throughout your whole body from your lungs
2. It is carried by your red blood cells through your blood stream
3. Cellular respiration only takes place in the lungs, so you do not need to transport oxygen
4. Oxygen is not necessary for cellular respiration

Answers

Answer:

2.  It is carried by your red blood cells through your blood stream.

Explanation:

The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.

Answers

Hello. Unfortunately your question is incomplete, which makes it impossible for it to be answered. However, through the context, we can see that your question is asking you to describe the cellular structures that you can see through a microscope.

To answer this question, you will need to look at biological material under a microscope to see what cells this material has and the structures it has. To do this, you will need to determine what material you will be using. This material can be a leaf, flower, a piece of fruit, or any other material that contains cells. After choosing the material, you need to search for a protocol, a tutorial, that shows how this material can be prepared so that the cells can be visualized through a microscope. This protocol can be found on the internet and in articles. You must follow the entire protocol to the letter, to be able to identify the cellular structures.

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?

Answers

Answer:

mRNA

Explanation:

There are three types of ribonucleic acid (RNA) viz: messenger RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA). These three RNA types function differently from one another. mRNA is a type of RNA that conveys genetic information that was previously stored in DNA into the ribosome for translation i.e. synthesis of amino sequence.

In other words, mRNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain using the amino acid sequence that arise from translating it in the ribosomes.

how can we apply the principle of transpiration in producing clean water?​

Answers

Explanation:

Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.

Answer:

During photosynthesis, the layer of TiO2 absorbs light, breaking down toxic pollutants in the water, while the gold layer emulates the transpiration of a leaf and harnesses sunlight to evaporate the water at the surface. The resulting vapor condenses into completely-purified water.

qué ventajas le trajo al ser humano el poder andar en 2 patas.

Answers

Answer:

The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".
