Answer:
The nucleus in eukaryotes and the cytoplasm in prokaryotes
Explanation:
The nucleus is the largest organ in a eukaryotic cell which is responsible for the control of the cell activities based on processing of received information and cell administration. The nucleus is therefore, known as the cell cell control center for regulating the metabolism of the cell and administers the cell and cellular information with which proteins are made
The nucleus contains nucleolus and it is the store for the chromosomes, which play an important role in genetics, related to the synthesis and replication of DNA and RNA
The functions of the nucleus are spread out through out the cytoplasm of prokaryotes.
Answer:
6.78 × 10⁵ J
Explanation:
Step 1: Given and required data
- Latent heat of vaporization of water (ΔH°vap): 2260 J/g
Step 2: Calculate the heat (Q) required to vaporize 300 grams of water
We will use the following expression.
Q = ΔH°vap × m
Q = 2260 J/g × 300 g
Q = 6.78 × 10⁵ J
6.78 × 10⁵ Joule will be required to convert 300 g of water to steam at 100 °C.
- 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
Answer: 0.25mol
Explanation: RMM of compound = (3 x 1) + (30) + (16 x 4) = 97g
# of moles = 25g / 97g = 0.25mol
During the first step of a redox reaction, the enzyme dehydrogenase strip hydrogen atoms from organic fuel.
<h3>WHAT IS AN ENZYME?</h3>
An enzyme is a biological catalyst that regulates the rate of a chemical reaction. Enzymes are of different types and are specific in function.
Dehydrogenase is a specific kind of enzyme that reduces/oxidizes molecules by removing or adding hydrogen atoms in the molecule.
Therefore, during the first step of a redox reaction, the enzyme dehydrogenase strip hydrogen atoms from organic fuel.
