Answer:
See explanation
Explanation:
The process in which Haemoglobin works depends by the environmental conditions of blood, especially with the partial pressures of O₂ and CO₂ related with the concentration of these compounds. When blood enters in the lungs, the haemoglobin get oxygenated because there is a high concentration of O₂ (meaning that the partial pressure of oxygen is high), liberating CO₂ that will be exhaled. The haemoglobin saturated with oxygen is known as oxyhaemoglobin
When blood flows in the body, found in the tissues higher concentrations of CO₂ which is more efficiently united with the haemoglobin, liberating the oxygen in the tissues for cell respiration, the haemoglobin them has form a reaction with the CO₂ which will travel back to the lungs and the cycle will begin again.
The three ways in which CO₂ travel are: Diluted in the plasma, as bicarbonate and combined with proteins (Haemoglobin) as a carbamine compound.
The CO₂ diluted in plasma, is due to the great capacity of dilution of the CO₂ which could be almost 20 times higher than O₂ capacity of dilution.
Bicarbonate is formed in the red blood cell when CO₂ and the enzyme name carbonic anhydrase reacts with water, forming a carbonic acid, when the concentration of these ions is elevated the carbonic acid becomes bicarbonate liberating a H₊ wich is united in the haemoglobin.
Carbamine compound form in the proteins families of the globines, being the most important the reaction in the haemoglobin.
Answer:
Moderate alcohol consumption, regardless of beverage type, reduces risk of coronary heart disease (CHD) among men and older women. There is strong evidence to support that ethanol, the main constituent in alcoholic beverages, is causally related to lower risk of CHD through changes in lipids and hemostatic factors.
Although heavier drinkers are at increased risk for some heart diseases, moderate drinkers are at lower risk for the most common form of heart disease, coronary artery disease (CAD) than are either heavier drinkers or abstainers.

Answer:
Spend more time outdoors, eat more red meat, supplement their deficiency with vitamins
Explanation:
Hello!
Vitamin D is a very important micronutrient within our bodies. This is due to its ability to regulate the amount of calcium and phosphate in the body. If a patient is Vitamin D deficient it can lead to a magnitude of problems such as bone deformities such as rickets, significant loss in bone density and depression. Thankfully, Vitamin D is one of the easiest vitamins to obtain. If a patient is not at risk for Melanoma, or other forms of skin diseases, they can obtain Vitamin D by simply spending more time outdoors in direct sunlight. Vitamin D can also be obtained through altering ones diet to include more red meat, egg yolks, liver, fish, and select breakfast cereals. If these options are not applicable to a patient a healthcare physician can supplement them in the form of Vitamin D tablets of varying concentration.

Answer:
c. facilitated diffusion requires an integral protein
Explanation:
Facilitated diffusion is process of the spontaneous passive transport (high to low concentration) of molecules or the ions across biological membrane by using specific trans-membrane proteins.
Facilitated transport does not require chemical energy from the ATP hydrolysis as it is a passive transport.
On the other hand, simple diffusion is the transport of the molecule from high tot low concentration without the use of a specific molecule.
Option A, B, D and E are incorrect.
