Your nose is a sensory organ and it’s function is to be able to smell chemicals, it cleans the air you breathe, it regulates the temp of the air you breathe, and it’s the main route for your breathing.
Answer:
Photosynthesis transforms light energy into chemical energy by making sugars. Cellular respiration releases the chemical energy from food by breaking down sugars.

Answer:
0.550
Explanation:
The absorbance (A) of a substance depends on its concentration (c) according to Beer-Lambert law.
A = ε . <em>l</em> . c
where,
ε: absorptivity of the species
<em>l</em>: optical path length
A 45 mM phosphate solution (solution A) had an absorbance of 1.012.
A = ε . <em>l</em> . c
1.012 = ε . <em>l</em> . 45 mM
ε . <em>l</em> = 0.022 mM⁻¹
We can find the concentration of the second solution using the dilution rule.
C₁ . V₁ = C₂ . V₂
45mM . 11mL = C₂ . 20.0 mL
C₂ = 25 mM
The absorbance of the second solution is:
A = (ε . <em>l</em> ). c
A = (0.022 mM⁻¹) . 25 mM = 0.55 (rounding off to 3 significant figures = 0.550)
Answer:
²⁵⁰₉₆Cm → ²⁴⁶₉₆Cm + 4 ¹₀n
Explanation:
The complete equation is;
²⁵⁰₉₆Cm → ²⁴⁶₉₆Cm + 4 ¹₀n
- The above equation is an example of a nuclear reaction in which unstable atom of Cm emits neutrons to become more stable.
- Radioactive isotopes undergo radioactivity or decay to attain stability, they do so by emitting particles such as alpha, beta particles or a neutron.
- An atom of Cm-250 undergoes decay and emits four neutrons to form an atom of Cm-246.
