The answer would be: Increased intracranial pressure caused by blood pooling in the head
A tumour will also apply pressure to the surrounding when growing. <span>It can also obstruct the nearby blood vessels, cause the blood or cerebral fluid to be trapped. The trapped fluid will increase the intra cranial pressure because the skull is a closed space organ. </span>
The sun rises in the east (and sets in the west).
Answer:
The correct answer is option c. "formation of protocells that use DNA to direct the polymerization of amino acids".
Explanation:
The polymerization of amino acids is a complex biological function that involves multiple proteins and cofactors working together at different locations in the cell. Even though there are some scientific advances in the production of synthetic protocells (cell like structures made from synthetic particles), the formation of protocells able to synthesize amino acids from DNA directly has not been accomplished.
Answer:
55.7 moles of PCl₃ and 55.7 moles of Cl₂
Explanation:
The balanced chemical equation for the reaction in which phosphorus pentachloride (PCl₅) is decomposed in phosphorus trichloride gas (PCl₃) and chloride gas (Cl₂) is the following:
PCl₅(g) → PCl₃(g) + Cl₂(g)
According to the stoichiometric coefficients, 1 mol of PCl₅ produces 1 mol of PCl₃ and 1 mol of Cl₂. So, the stoichiometric ratios reactant/product are: 1 mol PCl₃/1 mol PCl₅ and 1 mol Cl₂/1 mol PCl₅. Thus, we multiply the stoichiometric ratios by the number of moles of reactant:
1 mol PCl₃/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol PCl₃
1 mol Cl₂/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol Cl₂
Therefore, 55.7 moles of PCl₃ and 55.7 moles of Cl₂ are obtained from the decomposition of 55.7 moles of PCl₅.
