The human body contains trillions of microorganisms — outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that's 2 to 6 pounds of bacteria), but play a vital role in human health.
Answer: <u>The human body contains trillions of microorganisms — dwarfing human cells by 10 to 1. Due to their little size, nonetheless, microorganisms make up just around 1 to 3 percent of the weight's (in a 200-pound grown-up, that is 2 to 6 pounds of microscopic organisms), yet assume a crucial function in human wellbeing. In 2016, a survey of over forty years of examination into the human microbiome found that there is zero logical proof to back this frequently refered to tidbit up. Rather, the proportion appears to be about 1.3-to-1, with the normal human playing host to around 100 trillion microorganisms, plus or minus. Rather, the proportion seems to be about 1.3-to-1, with the normal human playing host to around 100 trillion organisms, plus or minus. </u>

Explanation:
You can mix this up and paraphrase this into ur own words.
To determine the number of atoms of Boron that are present within 3.61 grams of Boron Trifluoride, it would be best to convert the grams to moles of the compound and then after that use the Avogadro's number to determine the number of molecules and then use the 1 to 3 ratio to determine the total number of Boron atoms.
KOH is a strong base and HBr is a strong acid and completely dissociates. The balanced equation for the reaction is; KOH + HBr ---> KBr + H₂O Stoichiometry of acid to base is 1:1 The number of KOH moles reacted - 0.50 M / 1000 mL/L x 48.0 mL = 0.024 mol number of HBr moles reacted - 0.25 M/ 1000 mL/L x 96.0 mL = 0.024 mol the number of H⁺ ions are equal to number of OH⁻ ions. Then the solution is neutral. pH of neutral solutions at 25 °C is 7. Therefore pH is 7
In an atom, the nucleus is composed of positive charged particles called protons and neutrons that have zero charge. Most of the mass of the atom is in the nucleus. The atom is surrounded by orbits of electrons that are mobile and are negatively charged.
Carbon is found in the biosphere stored in plants and trees. Plants use carbon dioxide from the atmosphere to make the building blocks of food during photosynthesis. Carbon is found in the hydrosphere dissolved in ocean water and lakes. Carbon is used by many organisms to produce shells.
