Answer:
D. A solution.
Explanation:
"Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution."
Answer:
First off Life sciences are anything concerned with the study of a living organisms. So ones that would be included would be, microbiology biology, botany, zoology, ecology, genetics and medicine, from what the dictionary states
Explanation:
Biology is the natural science that studies life and living organisms. Which also includes molecular interactions, including their physical structure.
Genetics, is the study of heredity and or the variation of inherited characteristics that we get from family.
Microbiology, is the branch of science which deals with microorganisms.
Let me know if this helps, if not I'll continue researching.
Membranes are barriers and “gatekeepers”, they only let certain molecules pass through them.
they also transport nutrients to the cell
Answer:
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Gravitational energy or gravitational potential energy is the potential energy a massive object has in relation to another massive object due to gravity. It is the potential energy associated with the gravitational field, which is released when the objects fall towards each other.
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Answer:
The mass of P₄O₁₀ (s) formed is 471.03 g
Explanation:
4PH₃(g) + 8O₂(g) → P₄O₁₀ (s) + 6H₂O (g)
This is the ballanced equation.
Every 4 moles of phosphine, 1 mol of tetraphosphorus decaoxide is generated.
Moles of PH₃ = Mass PH₃ / Molar mass PH₃
Moles PH₃ = 225 g / 33.9 g/m
Moles PH₃ = 6.63 moles
So the rule of three, will be:
If 4 moles of PH₃ generate 1 mol P₄O₁₀
Then, 6.63 moles of PH₃ generate (6.63 .1)/4 = 1.66 moles
If we want to know the mass:
Moles . Molar mass = mass
Molar mass P₄O₁₀ = 283.88 g/m
1.66m . 283.88 g/m = 471.03 g
