lysosomes and vacuoles both are cell organelles that are membrane bound, and used for storage.
lysosomes contain/ store digestive enzymes and also known as suicidal bags.
vacuoles contain/ store undigested/ waste materials

Answer:
A molecule with 32 percent or more amount of Cytosine.
Explanation:
DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.
The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.
Thus, the answer is molecule with 32 percent or more amount of Cytosine.
Answer:
This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.
The answer is: 30grams
Explanation:
According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M
Molarity or Molar concentration is calculated using the formula:
M= n/V
Where; M= Molarity (M) = 0.5M
n= number of moles (mol)
V= Volume (V) = 1L
Hence, number of moles (n) = M × V
n = 0.5 × 1
n = 0.5 moles.
To calculate the mass in grams of CH3COOH, we say;
Number of moles (n) × molar mass (MM)
Since atomic mass for (C= 12, H= 1 and O=16)
Molar mass of CH3COOH:
= 12 + 1(3) + 12 + 16 + 16 + 1
Molar mass of CH3COOH = 60g/mol
Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol
Mass = 30grams.
Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.
