Which line of evidence has been traditionally accepted as conclusive proof of evolution? the presumed age of the Earth the fossi
Nataly_w [17]

The most generally accepted form of conclusive evidence for the theory of Evolution is the fossil record.

<h3>What is the theory of Evolution?</h3>
  • The theory of evolution was proposed by Charles Darwin.
  • It states that as time passes, organisms evolve to better adapt to their environments.
  • This is closely related to natural selection, which is considered a <em><u>driving force of </u></em><em><u>evolution</u></em><em><u>. </u></em>

<h3>How the fossil record supports this theory</h3>
  • The fossil record provides essential data to support this claim.
  • The data comes in the form of the comparison between fossils of two closely related organisms, separated by a matter of generations, that <em><u>present changes in the genetic code that made them more apt for survival.</u></em>

Therefore, we can confirm that the most generally accepted form of conclusive evidence for evolution is the presence of <u>fossils </u><u>that show the genetic correlation between two organisms and the progression of </u><u>evolution </u><u>between them. </u>

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L
Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of CdCl_{2} = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = \frac{number of moles}{volume in litres}

putting the values in the above formula and rearranging it for volume:

volume = \frac{number of moles}{molarity}

volume = \frac{0.196}{3.91}

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.

Bună ziua, mă poate ajuta și pe mine cineva, spunândumi din ce substanțe este formată cărămida și care este formula
Ne4ueva [31]

Answer: De câte cărămizi am nevoie? Pentru un perete de cărămidă cu strat singular, înmulțiți lungimea peretelui cu înălțimea pentru a obține zona. Înmulțiți acea zonă cu 60 pentru a obține numărul de cărămizi de care ar trebui să aveți nevoie, apoi adăugați 10% pentru risipă. Acesta este răspunsul scurt și presupune dimensiuni „standard” de cărămidă și mortar.

A 62.6-gram piece of heated limestone is placed into 75.0 grams of water at 23.1°C. The limestone and the water come to a final
VMariaS [17]
M₁ = mass of water = 75 g
T₁ = initial temperature of water = 23.1 °C
c₁ = specific heat of water = 4.186 J/g°C

m₂ = mass of limestone = 62.6 g
T₂ = initial temperature of limestone = ?
c₂ = specific heat of limestone = 0.921 J/g°C

T = equilibrium temperature = 51.9 °C
using conservation of heat
Heat lost by limestone = heat gained by water
m₂c₂(T₂ - T) = m₁c₁(T - T₁)
inserting the values
(62.6) (0.921) (T₂ - 51.9) = (75) (4.186) (51.9 - 23.1)
T₂ = 208.73 °C
in three significant figures
T₂ = 209 °C
