Answer:
The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the
*founder effect
, allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of
*evolution
resulted in adaptation and
*natural selection
of the island population into a new
*species
over time. Some of the birds crossed to some of the other islands where they were
*geographically isolated
and evolved into more species occupying different niches.

What is the solubility of mg(oh)₂ at a ph of 12.70? (ksp mg(oh)₂ is 1.6 × 10⁻¹³)
Based on the calculations, the solubility of mg(oh)₂ at a pH of 12.70 is equal to 3.4 × 10⁻⁵ M.
Given the following data:
Ksp of mg(oh)₂ = 1.6 × 10⁻¹³pH = 12.70What is pH?pH is an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions that are present in a given solution. Thus, the power of hydrogen ions (pH) is generally used to identify or specify the acidity, neutrality, or basicity of any chemical solution.
First of al, we would write the properly balanced chemical equation for this chemical reaction:
[tex]Mg(OH)_2(s)\rightleftharpoons Mg^{2+} (aq)+ 2OH^{-}(aq)[/tex]
Mathematically, the Ksp for the above chemical reaction is given by:
Ksp = [Mg²⁺][OH⁻]²
Ksp = [x][2x]²
1.6 × 10⁻¹³ = 4x³
x = ∛4 × 10⁻¹⁴
x = 3.4 × 10⁻⁵ M.

An ellipse is represented by the equation . each directrix of this ellipse is a ________________________ from the center on the major axis.
The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.
How to determine the distance of the directrix?The equation of the ellipse is given as:
[tex]\frac{(x - 5)^2}{625} -\frac{(y - 4)^2}{225} =1[/tex]
The above means that:
a^2 = 625
a = 25
b^2 = 225
b = 15
Calculate c using:
c^2 = a^2 - b^2
This gives
c^2 = 625 - 225
Evaluate the difference
c^2 = 400
Evaluate the square root
c = 20
The equation of the directrix is
x - x₀ = ± a²/c
So, we have:
x - x₀ = ± 625/20
Evaluate the quotient
x - x₀ = ± 31.25
This means that, each directrix is 31.25 units from the center on the major axis.

When 14.0 g of zinc metal reacts with excess hcl, how many litres of h2 gas are produced at stp? zn(s) + 2hcl(aq) → zncl2(aq) + h2(g)
Convert the given mass of Zn to moles:
(14.0 g) (1/65.32 mol/g) ≈ 0.214 mol Zn
According to the balanced reaction, 1 mol H₂ gas is produced for every 1 mol Zn consumed in the reaction, so get the same number of moles of H₂.
Convert this amount of H₂ to a volume at STP:
(0.214 mol H₂) (22.4 L/mol) ≈ 4.80 L H₂

In stage 3 identify the structure that made the organism
Answer:
In the first and second stages, the two organisms may show similarities. But when it comes to stage 3 it is possible that the organism can show a different structure. The difference can be seen from for example the front legs, size, eyes, and others.
Explanation:
An organism when viewed in an ecosystem is a community that develops together with the physical environment as a system. Organisms will always adapt to the physical environment, otherwise organisms also affect the physical environment for the purposes of life.
