Answer:
The formation of magnesium chloride, MgCl2, is another example of ionic bonding. When magnesium reacts with chlorine, a magnesium atom loses two electrons and becomes a positively charged ion, Mg2+. At the same time, two chlorine atoms gain one electron each and become negatively charged chloride ions, Cl−.
Composite volcano erupts with massive cloud of smoke and ash towering above a large volcano with steep sides.
Explanation:
A volcanic terrain composed of slowly accumulated lava erupts out to the earth’s surface through vents or openings. Depending upon the type of vent and the flow of lava, volcanoes are classified into four basic types – Cinder cone, Composite, Shield, and Lava dome volcanoes.
A Composite volcano, also called Stratovolcano, arise from grandest large mountains. These mountains usually are tall with sides being even but steep.
These mountains are built by several layers of a repeated lava flow, cinders, volcanic ash, blocks and other volcanic material.
Due to these volcanoes arising from tall mountains, these can erupt and rise to great height to even above 8,000 feet from their surroundings.
Most of the tall mountains of the world like Mt. Rainier, Mt. Hood, Mt. Shasta, Mt. St. Helen in the USA, Mt. Cotopaxi in Ecuador, and Mt. Fuji in Japan are all composite volcanoes

The answer to this question would be: recessive gen from his father and recessive gene from his mother.
Cystic fibrosis is a genetic disorder that resulted from the defect at cystic fibrosis transmembrane conductance regulator<span> (CFTR). CFTR has a role in the production of mucus, sweat or the gastric juice.
</span>The disease is inherited by recessive autosomal gene, which means the patient should get the defective gene from both parents.
The correct answer is: B) "All roads lead to Rome"
Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle that connects carbohydrate, fat, and protein metabolism so “all the roads” from the different metabolic pathways come to this cycle.
Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
The genotype would be dominant and the phenotype would be a big nose (N).
