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.
<u>Answer:</u> The fraction of atom's mass contributed by nucleus is 0.99
<u>Explanation:</u>
Nucleons are defined as the sub-atomic particles which are present in the nucleus of an atom. Nucleons are protons and neutrons.
The isotopic symbol of Helium-4 atom is
Number of electrons = 2
Number of protons = 2
Number of neutrons = 4 - 2 = 2
We are given:
Mass of He-4 atom =
Mass of 1 electron =
Calculating the mass contributed by the nucleus =
Mass of the nucleus of He-4 atom =
To calculate the fraction of atom's mass contributed by the nucleus, we use the equation:
Putting values in above equation, we get:
Hence, the fraction of atom's mass contributed by nucleus is 0.99
The answer is c. because you have to increase concentration of h2
Answer:trifluoromethanesulfonic acid (CF3SO3H).
Explanation:
The trifluoromethanesulfonic acid (CF3SO3H) has a halogen atom which stabilizes the leaving group by withdrawal of charge from the SO3- moiety. The methanesulfonic acid (CH3SO3H) contains an electron pushing group which tends to destabilize the charge centre. The better leaving group will be the stabilized anion which in this case is trifluoromethanesulfonic acid (CF3SO3H). This typifies the role of stabilizing factors in formation of chemical species.
