Answer:
The correct option is C. The level of organization best represented by the corn plant is : organism, the level of organization directly above organ system organ system
Explanation:
An organism can be described as a living thing made up of organ systems.
Plants are organisms that have levels of organizations similar to animals. Cells in plants make up tissues. There are mainly two types of tissues in plants: the meristematic tissue and non-meristematic tissue.
Just like animals, plants have organ systems. There are two kinds of organ systems mainly in plants: the shoot system and the root system. Hence, option C is the correct option.
Explanation:
We have to find the number of moles of N₂ that are present in a sample that has a volume of 40.0 L at STP.
STP means Standard Conditions of Temperature and Pressure. These conditions are 273.15 K and 1 atm. We know that 1 mol of N₂ will occupy 22.4 L. We can use that ratio to find the answer to our problem.
1 mol of N₂ = 22.4 L
moles of N₂ = 40.0 L * 1 mol/(22.4 L)
moles of N₂ = 1.79 mol
Answer: 1.79 moles of nitrogen are present.
Answer:
two atoms share 1 pair of valenece electrons
Explanation:
because double bond is created when each of two atoms share 2 valenece electrons (1 pair of electrons = 2 electrons)
Answer: D : A is 3 : 2.
Explanation:
The law of definite proportion is being used here. The law states that a given compound always has the same proportion of its constituent elements by mass.
2a + b = c + 3d
This actually means that, two moles of “a” react with a mole of “b” to produce a mole of “c” and 3 moles of “d”
Using the concept of stoichiometry coefficients of d and a
d:a = 3:2
