Well the red blood cells ( erythrocytes) contain the oxygen carrying pigment known as haemoglobin. Hence RBCs carry oxygen to every cell ion the body.
The white blood cells ( leukocytes) form the cell mediated defence system of the body, they kill microbes and foreign particles either by phagocytosis or lysozymic reactions.
The platelets (thrombocytes) help in the blood clotting process.
This is my comparism of tne blood components.

Answer:
The introduction of new species in the new area make the specie invasive if there is no predator is present in that ecosystem because the predator helps in the controlling of the population of that invasive species. The big example of invasive species is rabbit in the Australia where rabbit become invasive when there is no predator is present in that region so they increase in population and destroy all vegetation of that region. So if there is no predator of a newly introduced species, it become invasive in future.
Explanation:
Quit smoking, The process of giving up tobacco use is known as smoking cessation, also referred to as quitting or halting. Nicotine, which is addictive and can lead to dependency, is present in tobacco smoke. As a result, withdrawal from nicotine frequently makes quitting difficult.
The first three days after quitting, when symptoms normally reach their climax, are followed by a period of around two weeks. It gets a little simpler when you get past those difficult first few weeks. What aids? Before quitting, you should start to create arrangements. What occurs when a smoker stops? Your breathing and capacity for exercise will start to dramatically improve.
Your chance of having a heart attack is greatly reduced. Your risk of developing laryngeal, throat, and mouth cancer is halved, and your risk of stroke is reduced. When compared to a smoker, your risk of acquiring lung cancer is decreased by half.

Answer:
D. acetyl CoA, NADH, H+, and CO2.
Explanation:
Pyruvate formed by the glycolytic breakdown of glucose enters Kreb's cycle in the form of acetyl CoA. Conversion of pyruvate into acetyl CoA occurs in the mitochondrial matrix and the reaction catalyzed by the pyruvate dehydrogenase complex (PDH). It is an oxidative decarboxylation of pyruvate.
The PDH complex is composed of multiple copies of three enzymes. The enzyme complex catalyzes an irreversible oxidation process in which the carboxyl group of pyruvate is removed as a molecule of CO2 and the two remaining carbons become the acetyl group of acetyl-CoA. Here, NAD+ serves as the electron acceptor and is converted into NADH.
Answer:
Mutations must not occur to introduce new alleles to the population. No gene flow can occur to increase variability in the gene pool. A very large population size is required to ensure allele frequency is not changed through genetic drift. Mating must be random in the population.
