NARA [144]

Answer:

False

Explanation:

Diffusion uses the concentration gradient that has been set up, this is a naturally occurring phenomena, and using a diffusion gradient some small particles can cross over the cell membrane. Some bigger or polar molecules require facilitated diffusion to move these molecules across the membrane.

Facilitated diffusion still uses the gradient for passive transport. This means that ATP is not used to transport molecules.

The reason that glucose will not move into the cell via passive transport is because there is a higher concentration of glucose inside the cell, meaning it needs active transport to move glucose (against the concentration gradient) into the cell.

How does carbon cycle through the ocean, atmosphere, soil, and biosphere?
saw5 [17]
Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
make sure to paraphrase and give thanks:) good luck

For the reaction 2A(g) â B(g), the equilibrium constant is Kp = 0.76. A reaction mixture initially contains 4.0 atm of gas (PA =
timofeeve [1]

Answer: (a) The reaction mixture will proceed toward products.

Explanation:

Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as K_p

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

2A(g)\rightleftharpoons B(g)

The expression for Q_p is written as:

Q_p=\frac{p_B}{(p_A)^2}

Q_p=\frac{(2.0)}{(2.0)^2}

Q_p=0.5

K_p=0.76

Thus as K_p>Q_p , the reaction will shift towards the right i.e. towards the product side.

Which element would mostly have chemical properties similar to that of magnesium (Mg)?
DanielleElmas [232]

The elements of same group are placed in same group as they have similar properties. So Calcium is the element which resembles Mangesium.

Calcium and Magnesium both are alkaline earth metals.

They have similar properties as they have similar outer or valence shell electronic configuration

The general electronic configuration of alkaline earht metal is ns2

The electronic configuration of Mg [atomic number 12] and Ca [atomic number 20] are

[Ne]3s^{2}  and [Ar]4s^{2} respectively.
