Answer:Global warming is the long-term heating of Earth's surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Explanation:
A genetic factor exhibiting a trait even in the presence of alternative forms is described as a dominant allele. Dominant alleles express over recessive genes, as exhibited in the height trait of pea plants.
A genetic factor for a trait that is always expressed when present is referred to as a dominant allele. In genetic terms, alleles are variations of a gene. In a pair of alleles, one can be dominant and the other recessive. When an individual possesses both the dominant and the recessive allele, the trait associated with the dominant allele gets expressed. For example, for the gene concerning height in pea plants, the allele for tallness is dominant over the allele for shortness. Thus, when a plant inherits the tall and short alleles together, the tall trait is expressed due to the dominance of the tall allele.

B. chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the red blood cells
C. as carbonic acid in the plasma
D. as the bicarbonate ion in the plasma
The bulk of carbon dioxide transported in blood is in many forms where the carbon dioxide is flowed inside the blood. The three ways in which the carbon dioxide is dissolved in many ways are as following :
(1) dissolved gas
(2) bicarbonate
(3) carbaminohemoglobin
Oxygen is the gas which is being replaced by the carbon dioxide, here in this position the exchange is present.
Chemically combined with the heme portion of hemoglobin that is carbon dioxide binds with the hemoglobin part that is required by the molecules to travel along.
Dissolved gas that is carbon dioxide mixing with the blood will help the deoxygenation to cope up where the deoxygenated blood will be removed from the blood.
The bicarbonate ion that is acting as buffer in order to maintain the blood pH where the blood will get a buffer help.

Yes, that's correct. Smoking is a well-known risk factor for various deadly diseases and health conditions. Cigarette smoke contains harmful chemicals that, when inhaled, can damage the respiratory system and other organs in the body.
Here are some of the deadly diseases and health conditions that smokers have a greater chance of developing:
Lung Cancer: Smoking is the leading cause of lung cancer. It increases the risk of developing this aggressive and often fatal form of cancer.
Chronic Obstructive Pulmonary Disease (COPD): Smoking is a major cause of COPD, which includes chronic bronchitis and emphysema. COPD is a progressive and debilitating lung disease that can significantly reduce a person's quality of life and, in severe cases, lead to death.
Cardiovascular Diseases: Smoking damages the blood vessels, increases blood pressure, and raises the risk of heart attacks, strokes, and other cardiovasculardiseases. It is a significant risk factor for coronary artery disease.
Respiratory Infections: Smokers are more susceptible to respiratory infections, such as pneumonia and bronchitis, due to the weakening of their immune system and the damaging effects of smoking on the respiratory tract.
Cancers in Other Organs: Smoking is associated with an increased risk of developing cancers in various other organs, such as the mouth, throat, esophagus, pancreas, kidney, bladder, and cervix.
Peripheral Vascular Disease: Smoking damages the blood vessels in the legs and arms, leading to reduced blood flow, pain, and increased risk of infections and gangrene.
Weakened Immune System: Smoking weakens the body's immune system, making it harder to fight off infections and diseases.
It is essential for smokers to be aware of these risks and to take steps to quit smoking. Quitting smoking significantly reduces the risk of developing these deadly diseases and can improve overall health and well-being. Additionally, avoiding exposure to secondhand smoke is crucial, as it can also pose health risks to non-smokers.
