Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.
For the answer to the question above, I think that Few Fossils exist from this time because the animals were all soft-bodied. Most of the animals dissolve or decompose immediately and turn to dust because they are soft-bodied.
Answer:A-wave X is transverse and wave Y is longitudinal
Explanation:
Answer:
Correct option is White
Explanation:
Germinating seeds carry out their
respiration process at the cellular level to
be able to generate energy for growth and
maturation.
They do not yet have the ability to carry out
photosynthesis.
As a result of respiration, carbon dioxide is
released by the seeds which turn lime
water milky or white.
So the correct answer is 'White
Answer:
The statement that best describes the vascular tissue in seed plants is that xylem carries water and nutrients from the roots to the rest of the plant.
Explanation:
Xylem corresponds to the tissue of the vascular plants that is responsible for the transport and distribution of liquids necessary for their development.
The main function of xylem is to<u> carry water, mineral salts and other nutrients -in the form of raw sap- from the root to the whole plant</u>, forming a network similar to the circulatory system of higher animals.
