Answer:
No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.
Explanation:
The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.
Answer: D. Water will enter and exit the cells at a steady rate and their sizes will remain the same.
Explanation:
Osmosis occurs when the salt content is NOT the same as our red blood cells: the salt or lack of it causes our RBCs to swell or shrink. Isotonic fluid has the same salt content as our RBCs. This is why it's important to watch salt intake in congestive heart failure.
The graph is a visual representation of information. It is shown by the x and y-axis. f(x)=x²+3.

What is a graph?</h3>
The graph is a visual representation of information. It is shown by the x and y-axis. The given equation is f(x)=x²+3.
In first case, f(x)=x²+3, x = − 3
f(x)=x²+3
= (− 3 ) ² + 3
= 9+ 3
= 12
f(x)=x²+3 = (− 2 ) ² + 3
= 4+ 3
=7
f(x)=x²+3
= (− 1 ) ² + 3
= 1 + 3= 4
Therefore, The graph is a visual representation of information. It is shown by the x and y-axis.

Out of the following given choices;
mucosa
serosa
submucosa
muscularis externa
The answer is muscularis externa. This layer is one of the 4 layers (tunics) of the GI tract. It is found beneath the submucosa and is composed of smooth muscles. The smooth muscles are responsible for the involuntary movements called peristalsis, that move food along the gastrointestinal tract.
Answer:
Food is necessary to digest because food we eat is made of macromolecules.
Explanation: Macromolecules such as carbohydrates, proteins and lipids which are made of many small molecules i. e. glucose, amino acid and fatty acid respectively. Our body absorb food in the form of glucose, amino acid and fatty acid so it is necessary that the food is broken down into these small molecules.
