No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
Answer:
Atoms are smallest unit of matter
Explanation:
Answer and Explanation:
Carbon dioxide (CO₂) dissolves in water and gives carbonic acid (H₂CO₃) which then dissociates first in HCO₃⁻ and then in CO₃⁻. So, its ionization increases the concentration of H⁺ and the solution becomes more acidic. If you measure the pH of a sample by using a colorimetric indicator and then you exhale your CO₂ in the sample, you will see that the indicator changes its color to the correspondent to a acid solution.
Answer:
Exothermic
q = -8.03 kJ/g
Explanation:
<em>When 2 moles of Na(s) react with H₂O(l) to form NaOH(aq) and H₂(g) according to the following equation, 369 kJ of energy are evolved.</em>
The thermochemical equation is:
2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) ΔH = -369 kJ
Since the energy is evolved, the reaction is exothermic, which is why the enthalpy of the reaction (ΔH) is negative.
The heat released (q) per gram of Na(s) is (molar mass 22.98 g/mol):
