Answer:
A. Left ventricle; systemic
Explanation:
The ventricles are located on the posterior end of the heart beneath their corresponding atrium. The right ventricle helps to receives deoxygenated blood from the right atria and pumps it through the pulmonary vein and into pulmonary circulation, then transported into for gas exchange via the lungs.
The left ventricle receives oxygenated blood from the left atria and pumps it through the aorta into systemic circulation in order to supply the tissues of the body with oxygen.
The walls of the ventricles are the thickest and strongest. This is because the amount of work on the left ventricles, which pump blood throughout the body and lungs, is much greater than the pressure generated by the atria to fill the ventricles.
Snapper overfishing
Explanation:
Coral reefs are becoming highly vulnerable due to increased anthropological exploitation of the ocean reserves. Overfishing, usage of non-selective fishing gears, fishing the spawning areas, fishing using nets etc all affect the coral reefs and the marine ecosystem. The coral reefs and the fish population are interdependent and overfishing greatly impacts both the factors.
Overfishing is the main reason for damage and decline in coral reefs. The snappers are carnivores and survive on eating other fishes which can be herbivores or omnivores. Snappers remain at the top of the food pyramid of the marine ecosystem. A reduction at the top level of the food pyramid will automatically disturb the lower level population and the energy flow between each cycle. A reduction in carnivores leads to increase in herbivores which in turn deplete the coral reefs. Coral reef is a habitat for many fish populations, and a reduction in the habitat will again reduce the overall population of fishes. A decrease in predator population will increase prey population.

Explanation:
Answer: Atoms are the basic building blocks of all matter, living and nonliving. They are made up of subatomic particles (neutrons, protons, and electrons)
Explanation:
Hope thats correct and helps! :)
The answer is: A. True
Complex sugars or polysaccharides are composed of basic units called monosaccharides that are linked via glycosidic bonds. Glycosidic bond is formed through condensation reactions (water is released) that occur between a hydroxyl (OH) oxygen atom on one sugar and the α-anomeric form of C-1 on the other. There are are two types of glycosidic bonds:
- 1,4 alpha ( the OH is below the glucose ring)
- 1,4 beta glycosidic bonds (the OH is above the glucose ring)
Amylase is an enzyme that breaks down starch into smaller glucose molecules, it act on α-1,4-glycosidic bonds and it works in mouth where the digestion begins (salivary amylase) . Maltase breaks down maltose into glucose; sucrase, breaks down sucrose into glucose and fructose; and lactase, which breaks down lactose into glucose and galactose work in small intestine and also act on α-1,4-glycosidic bonds.
