Nombra de forma ordenada el camino que recorre el CO2 desde el capilar sanguíneo que rodea el alveolo hasta salir del cuerpo.
Answer:
El aire ingresa al cuerpo a través de la boca o la nariz y se mueve rápidamente hacia la faringe o la garganta. Desde allí, pasa a través de la laringe o laringe y entra en la tráquea.
La tráquea es un tubo fuerte que contiene anillos de cartílago que evitan que se colapse.
Dentro de los pulmones, la tráquea se ramifica en un bronquio izquierdo y derecho. Estos se dividen aún más en ramas cada vez más pequeñas llamadas bronquiolos.
Los bronquiolos más pequeños terminan en diminutos sacos de aire. Estos se llaman alvéolos. Se inflan cuando una persona inhala y se desinflan cuando una persona exhala.
Durante el intercambio de gases, el oxígeno pasa de los pulmones al torrente sanguíneo. Al mismo tiempo, el dióxido de carbono pasa de la sangre a los pulmones. Esto sucede en los pulmones entre los alvéolos y una red de pequeños vasos sanguíneos llamados capilares, que se encuentran en las paredes de los alvéolos.
Aquí puede ver los glóbulos rojos que viajan a través de los capilares. Las paredes de los alvéolos comparten una membrana con los capilares. Eso es lo cerca que están.
Esto permite que el oxígeno y el dióxido de carbono se difundan o se muevan libremente entre el sistema respiratorio y el torrente sanguíneo.
Las moléculas de oxígeno se adhieren a los glóbulos rojos, que viajan de regreso al corazón. Al mismo tiempo, las moléculas de dióxido de carbono en los alvéolos salen del cuerpo la próxima vez que una persona exhala.
El intercambio de gases permite que el cuerpo reponga el oxígeno y elimine el dióxido de carbono. Hacer ambas cosas es necesario para sobrevivir.

In your letter, you need to explain how ether theory of evolution is supposed by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.
Answer: The four pieces of evidence for Evolution are:
--> Fossil records,
--> biochemical similarities,
--> molecular records and
--> embryology.
Explanation:
Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. Indirect evidence that supports the theory of evolution has been gathered by scientist from many fields. These evidence include:
--> Fossil records: These are data gotten from the remains of organisms preserved mainly in earth's sedimentary rocks. By arranging the fossils according to their age, from the oldest to the youngest, they have been able to show an evolutionary trend from very simple life forms to complex ones. An EXAMPLE is the evolution of the modern horse (equus) from the dawn horse, eohippu, 60 million years ago.
-->Biochemical similarities: the chemical make-up and biochemical processes of all organisms are very similar. For EXAMPLE, all organisms use the same material and processes for storing, expressing and transmitting genetic information.
--> Molecular records: All organisms store hereditary information in nucleic acids, mainly DNA. In present day evolutionary theory, changes are recorded in these macromolecules by alterations to existing chemical structures. Therefore, the DNA of closely related species should show more similarities than those of distant species. For EXAMPLE, the DNA of humans and Chimpanzees is 98% alike.
--> Embryology: In many cases, the embryo of an organism resembles the embryo of its ancestors during certain very transitory stages of its development. For EXAMPLE, the human embryo has gill slits like a fish at an early stage in its development.

how does plant has DNA
Answer: Hello, there! Your Answer is Below
The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts. DNA is a coded set of instructions for making RNA.
Explanation:
Plants are unique in that they are able to produce energy-dense carbohydrates via photosynthesis, a process which is achieved by use of chloroplasts. Chloroplasts, like the superficially similar mitochondria, possess their own DNA.
Hope this helps!
Have a great day!!
Plants use deoxyribonucleic acid (DNA) as their genetic material. DNA gives a coded set of instructions that make RNA. All the functions of the plant cell are controlled and managed by the nucleus.
What causes the electric field of flowers?
Answer:
The Electric Minute they produce makes bees attractid to them. Causing them to produce more electricity.
Explanation:
Bees don't just recognize flowers by their color and scent; they can also pick up on their minute electric fields. Such fields—which form from the imbalance of charge between the ground and the atmosphere—are unique to each species, based on the plant's distance from the ground and shape.
Which best describes how an organism’s niche is determined?
An organism's habitat and inherited traits determine its niche.
An organism’s habitat and ability to reproduce determine its niche.
An organism's size and ability to fight determine its niche.
An organism's population and prey determine its niche.
The option that describes how an organism’s niche is determined is A. An organism's habitat and inherited traits determine its niche.
A niche simply refers to the role that is played by a particular organism in the ecosystem. It simply includes the role that the organism plays in the flow of energy in the ecosystem.
It should also be noted that the niche of an organism has to do with the interaction between the organisms that are in the ecosystem.
Therefore, the determination of the niche of an organism is based on the
organism's habitat and inherited traits.

HELP!!!! two questions pls :)
Answer:
1.
To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).

B-the acid rain burns the skin of local animal life, causing deaths in these populations
C-increased erosion of bedrock causes more mudslides that destroy habitats
D-the reduction in soil pH makes it difficult for native plant species to grow
Answer:
A
Explanation:
took the exam and this was the right answer (connexus)
The effects of acid rain are most evident in a tundra biome because the acid rain causes the snow to become darker, which increases snowmelt.
What do you mean by Acid rain?Acid rain may be defined as any form of rain with acidic components, such as sulfuric or nitric acid that tumble to the ground from the atmosphere in wet or dry forms.
The tundra biome is mostly surrounded by solid ice throughout the year. The average temperature is found to be very low.
Acid rain increases the contamination of ice, due to this deposition ice becomes darker, and melts gradually.
Therefore, the effects of acid rain are most evident in a tundra biome because the acid rain causes the snow to become darker, which increases snowmelt.

Let's say your name is Gilligan, you've survived a shipwreck and you're stranded on a desert island. You happen to have been stranded with a medical doctor that has a limited stock of medical supplies. One of your shipmates is in desperate need of a blood transfusion but doesn't know his blood type. You do know your blood type. How could you type his blood with your knowledge and limited medical supplies?
Answer:
In order to find the blood type of the shipmate, Gilligan mixes a little blood of the shipmate with himself firstly and than with individual blood types to simplify the data by process of elimination.
Explanation:
There are a total of four types of blood groups which are as follows:
A blood grp has anti B antibodies, has A antigen B blood group has anti A antibodies, has B antigen AB blood group has no antibodies, has A and B antigen O blood group has no antigens, has anti A and anti B antibodiesIn order to find the blood type of the shipmate in the deserted needs of a blood transfusion, mixing of your blood with some of his blood is carred out:
if no clumping seen then the shipmate has same type of blood group as you or has AB blood group (AB has no antibodies). If clumping is seen then person has O blood group(has both anti A and anti B antibodies) or the other type of blood group (that is if Gilligan's blood group is type B, if clumping is seen then the other person's blood group is O or A type because he has anti B antibodies in both of them)With your partner list three biological processes involving biosynthesis break down what you think your body could carry out using the matter and energy from the beef burger
