A cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of a corn plant. Based on this observation
Alik [6]

Answer:

This question lacks options, the options are:

A). synthesizes more sugar

B). has a higher chromosome count

C). produces fewer proteins

D). uses less carbon dioxide

The answer is A

Explanation:

The chloroplast is an organelle present in the cells of photosynthetic organisms. It is the site where photosynthesis, which is the production of food (sugars) from sunlight energy, occurs.

According to this question, a cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of the same corn plant. Based on this observation, it can be inferred that the LEAF CELLS WILL SYNTHESIZE MORE SUGARS THAN THE STEM CELL because the more the chloroplast, the higher the photosynthetic rate and subsequently the higher the amount of sugar produced.

A gas at constant volume has a pressure of 3.20 atm at 300. K. What will be the pressure of the gas at 290. K?
melomori [17]
  • From the general law of gases: PV = nRT,

where P is the pressure (atm),

V is the volume (L),

n is the number of moles,

R is the general gas constant (8.314 L.atm/mol.K),

T is the temperature in Kelvin

  • at constant volume of the gas: P1T2 = P2T1

P1 = 3.20 atm, T1 = 300 K, T2 = 290 K, P2 = ??

(3.20 atm)(290 K) = P2(300 K)

P2 = (3.20 atm)(290 K)/ (300 K) = 3.093 atm

If f(x)=x^2 and g(x)=2x+3, what is f(g(x))
IgorC [24]

Answer:

\huge\boxed{f(g(x)) = 4x^2 + 12x + 9}

Explanation:

In its raw form, function notation essentially represents an equation with only one unknown variable, expressed in terms of another.  Thus, f(x) = x² + 7x can be expressed as

g(x) = 2x + 3

f(g(x)) = (2x + 3)²

f(g(x)) = 4x² + 12x + 9

Hope it helps :) and let me know if you want me to elaborate.

Observe: click reset. select the gas collection setup. chemists use this apparatus to collect any gases produced in the reaction
Oxana [17]

Hello. Although it is not possible to see the video to which the question refers, we can see, in the question, that water is removed from the cylinder as a gas is added to the same cylinder. So we can see that a gas was produced in the reaction, through the displacement of water, that is, if the water starts to be removed from the cylinder, it is because the reaction is producing a gas. If the gas is not produced, water will not come out of the cylinder.
