Answer: The correct answer is-
C.accurate.
As per the information in the question, a group of scientists has proposed a new theory on Adaptation, which is accepted by majority of scientists worldwide. This indicates that the proposed theory is most likely to be accurate.
A scientific theory is an explanation of certain aspects of nature that is based on some facts as well as evidences. It is tested, observed, and proven right on the basis of repeated experimentation.
As the theory on Adaptation is accepted by majority of the scientists, it means that it is most likely to be accurate.
Thus, option C) is the right answer.
B. 196 m
C. 260 m
D. 162.5 m
The Correct answer to this question for Penn Foster Students is: 137.5 m
Electrophiles are positively charged or neutral species having empty orbitals that are attracted to an electron rich center. Examples of these are the Bronsted acid. Bronsted acid accepts an electron pair for hydrogen.
(2) Add 30. g of solute to 970. mL of solvent to make 1.0 L of solution.
(3) Add 1000. g of solvent to 30. g of solute.
(4) Add enough solvent to 30. g of solute to make 1.0 L of solution.
A student wants to prepare a 1.0-liter solution of a specific Molarity. The student determines that the mass of the solute needs to be 30. grams. Add enough solvent to 30. g of solute to make 1.0 L of solution.
The proportion of solute moles to solution length is known as molarity. By dividing the number of moles of HCl by the volume (L) of the solution in which it was dissolved, we may get the acid solution's molarity.
A chemical species' concentration in a solution, specifically the amount of a solute per unit volume of solution, is measured by its molar concentration.
A mole is a unit of measurement for a chemical substance, and it is from this unit that the word "molarity" is derived. The method of figuring out how much of a material a certain chemical solution contains is known as molecularity, sometimes known as the molar concentration of a solution.
Thus, option 4 is correct.

A black hole collapsed to form the sun; small planetary objects formed; small planetary objects collided with each other to form larger objects.
B.
Most of the dust and gas contracted into a central mass—the Sun; half the mass of the cloud condensed to form Jupiter; asteroids and comets crashed into the sun to form the smaller planets.
C.
A spinning cloud of dust began to compress to form the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets.
D.
Gravitational force held the newly formed planets around the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets.
The statement about the formation of the solar system that are true and in a correct order are Gravitational force held the newly formed planets around the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets. The answer is letter D.
