Which of the following investigators was (were) responsible for the following discovery? In DNA from any species, the amount of

Zarrin [17]

Answer :Erwin Chargaff a Biochemist

Explanation:

He formulated the base paring of double helix of DNA. He reasoned that since the percentage of four DNA bases are of this proportions in human;

Adenine=30.9% and Thymine =29.4%;

Guanine=19.9% and Cytosine =19.8%

Then, the amount of adenine will always be equal to thymine,

And the amount of Guanine equals to cytosine based on this percentages of distribution.

(Adenine and Guanine are large, molecule of Purines, while thymine and Cytosine are Pyrimidine)

He concluded (although scientist believed, he did not explicitly stated this) that this should be the base paring patterns in DNA molecule. This is the first Chargaff Rule.

His second rule is that the DNA composition, in the relative amount of the four bases Adenine, Thymine, Cytosine and Guanine varies in proportion from one organisms to another. And this is the basis of molecular diversity.

This would be mitosis. mitosis consist of four main parts interphase,prophase,metaphase, anaphase, and telophase which also included cytokinesis which you can also study this term by using this terminology ( I P M A T )

How come one type of matter can be converted to a totally different one?

wariber [46]

Answer:

Explanation:

En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.

Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1 la palabra está relacionada con māter («origen, fuente, madre»)2 y se corresponde con el griego hyle3 (de hylos: «bosque, madera, leña, material»)45 que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6

El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.

Which of the following samples will have the greatest volume at STP?a. 22 g Neb. 22 g Hec. 22 g O2d. 22 g Cl2 e. All have the sa

sammy [17]

Answer:

22g of He

Explanation:

Volume of gas at STP is given as :

Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹

In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.

Number of moles = $\frac{mass }{Molar mass}$

Now, let us obtain the molar mass of the given atoms and elements:

For Ne; molar mass is the atomic mass = 20gmol⁻¹

He = 4gmol⁻¹

O₂ = (16 x2)gmol⁻¹ = 32gmol⁻¹

Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹

Number of moles of Ne = $\frac{22}{20}$ = 1.1mol

Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³

Number of moles of He = $\frac{22}{4}$ = 5.5mol

Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³

Number of moles of O₂ = $\frac{22}{32}$ = 0.688mol

Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol

Number of moles of Cl₂ = $\frac{22}{71}$ = 0.3099mol

Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³
