me too please l need to know how to use this
Answer:
D. Kingdom Fungi includes organisms that get energy by absorbing materials in their environment.
Explanation:
Organisms in the domain Eukarya are characterized by the possession of a well defined NUCLEUS in their cells. Kingdoms in this domain include animalia, plantae and fungi.
- Kingdom animalia contains multicellular organisms that are strictly heterotrophic i.e. cannot synthesize their own food, hence, rely on other organisms for nutrition.
- Kingdom plantae contains multicellular organisms that are capable of movement but not independently i.e. they cannot move from their fixed positions.
- Kingdom Fungi includes organisms that get energy by absorbing materials in their environment via a structure called MYCELIUM.
Answer and Explanation:
The equation that depicts oxidation of neutral atom A is shown below:
This is because one species is losing electrons due to oxidation. The species possesses positively charged after losing electrons, the magnitude of which is proportional to the number of electrons lost.
The net charge will be equivalent on both sides of the equation, too.
Therefore all other options are not correct
The equation that depicts the decline of neutral atom X is
It is how a cell gains electrons by reduction. The species obtains a negative charge upon possessing electrons, whose magnitude is equivalent to the amount of electrons gained.
The net charge will be equivalent on both sides of the equation, too.
Therefore all other options are not correct
A, B, and D. You already answered the first one, so I wouldn't think this would be too hard

Answer:
4.6g
Explanation:
We are given the following parameters:
Molecular weight of the compound = 74g/mol
Volume = 2500mL = 2.5L or 2.5dm³
Concentration = 0.025M
Unknown:
Mass of compound = ?
Solution:
To solve this problem, we need to find the number of moles from the given concentration and volume values.
Number of moles = concentration x volume
So;
Number of moles = 0.025 x 2.5 = 0.0625mol
Therefore, mass of compound;
Mass = number of moles x molar mass
Mass = 0.0625 x 74 = 4.6g
