Answer:
Explanation:
DNA replication occurs in several steps that involve multiple proteins called replication enzymes, as well as RNA. DNA replication is vital for cell growth, repair, and reproduction in organisms.
There are three main steps to DNA replication: initiation, elongation, and termination.
Answer:
Boron and Aluminium
Explanation:
Boron and Aluminium are present in Group 13 of the modern periodic table. Group 13 (IUPAC System) can also be referred to as Group III-A. Logically, Boron and Aluminum can't be placed alongwith elements such as Yttrium as they don't exhibit properties of a transition metal.
Answer:
- 75.5 g O₂ (g) can be produced from 42.6 g of H₂O (g)
Explanation:
<u>1) Balanced chemical equation (given):</u>
<u>2) Mole ratios:</u>
- 2 moles H₂O(g) : 2 moles H₂(g) : 2 moles O₂(g)
<u>3) Calculate the number of moles of reactant (H₂0):</u>
- number of moles = mass in grams / molar mass
- molar mass of water: 18.015 g/mol
- mass in grams of water: 42.6 g
- number of moles = 42.6 g / 18.05 g/mol = 2.36 moles H₂O
<u>4) Set a proportion using the mole ratio O₂ to H₂O and the actual number of moles of H₂O:</u>
- 2 moles O₂ / 2 moles H₂O = x / 2.36 moles H₂O
<u>5) Convert 2.36 moles O₂ to grams:</u>
- mass in grams = number of moles × molar mass
- mass = 2.36 moles × 32.00 g/mol = 75.5 g O₂
Many protons would bypass ATP synthase, resulting in a sudden decline in ATP synthesis.
Friedrich Mohs devised a scale that tested mineral <span>hardness, </span>which means the resistance of a mineral to being scratched. This scale (from 1 to 10) is known as the Mohs Hardness Test. Objects are used as tools to perform the hardness test:
<span>fingernail (hardness = 2,5).
copper penny (hardness = 3)
glass plate or steel knife (hardness = 5,5)
<span>steel file (hardness = 6,5).
According to this scale </span></span><span>hardness of the mineral is between 5,5 and 6,5.</span>
