Explanation:
The question is incomplete, the complete question is;
The levels of organizations in multicellular organisms are shown below, but they are not in the correct order. Arrange the levels of organization in order from simplest to most complex. tissues organs whole organisms organ systems
Answer:
tissues --> organs --> organ system --> whole organisms
Explanation:
The levels of organizations in multicellular organisms refers to the increasing complexity of the components of the organism.
A tissue is an aggregation of cells hence it is the lowest level of organization here.
Organs are an aggregation of tissues, this is the next higher level of organization.
Organ systems are an aggregation of organs, this is the next higher level of organization.
Whole organisms are an aggregation of organ systems. This is the highest level of organization.
Answers:
(a) 508 THz; (b) 337 zJ
Step-by-step explanation:
The formula relating the frequency (f) and wavelength (λ) of a photon is
fλ = c Divide both sides by λ
f = c/λ
The formula for the energy of a photon is
E = hf
Data:
c = 2.998 × 10⁸ m·s⁻¹
λ = 590 nm
h = 6.626 × 10³⁴ J·s
Calculations:
(a) <em>Frequency
</em>
f = 2.998 × 10⁸/(590 × 10⁻⁹)
= 5.08 × 10¹⁴ s⁻¹
= 508 × 10¹² s⁻¹
= 508 THz
(b) <em>Energy
</em>
E = 6.626 × 10⁻³⁴ × 508 × 10¹²
= 3.37 × 10⁻¹⁹ J
= 337 × 10⁻²¹ J
= 337 zJ
<span>We know that density is equal to mass divided by volum, D=M/V and in this case we have 1 gallon of a solution of sulfuric acid with 37.4% of concentration in mass.
1 gallon is 3785.41 ml and according the formula M=D*V = 1.31 * 3785.41 = 4958.89 grams of solution.
Only 37.4% of the solution is sulfuric acid, that is 4958.89 * 37.4/100= 1854.62 grams
Then the number of grams of sulfuric acid is 1854.62 gr.</span>
Answer
is: molar solubility of barium carbonate is 4.47·10⁻⁵ M.
Chemical
reaction:BaCO₃(s) →
Ba²⁺(aq) + CO₃²⁻(aq).
Ksp
= 2.0·10⁻⁹.
s(BaCO₃) = ?M.
s(BaCO₃) = s(Ba²⁺)
=s(CO₃²⁻) = x.
Ksp
= s(Ba²⁺) · s(CO₃²⁻).
Ksp
= x · x.
2.0·10⁻⁹ =
