<span>The cell cycle is divided into two main parts interphase and mitosis. Mitosis is when the cell divides and this process is taken up by the process of dividing. Interphase is broken down into several phases: G1, growth occurs (cytoplasm increases); S, DNA synthesis (replication) occurs; and G2, growth occurs (cytoplasm increases and organelles are replicated).
So the answer is b) Cytoplasm increases, and organelles and DNA are replicated</span>

Answer: For (a):
(Lys-Ala)3 is soluble and (Gly)zo is not soluble.
(b) (Glu)zo is soluble and (Phe-Met) is not soluble.
(c) ( Asn-Ser-His) is soluble and (Ala- Asp-Gly) is not soluble.
(d) (Asn-Ser-His) is soluble and (Ala-Ser-Gly).
Explanation:Firstly, the solubility of polypeptides relies on polar groups in the R group of the side chain and also ionized groups because these groups can interact with dipole bond of water.
For (a): (Gly)zo, no R group of the side chain of (Gly)zo is polar nor ionizable and solubility is based on the ability of R group of polypeptides to be polar or ionized while in polypeptides of (Lys-Ala), Lys is polar and therefore soluble though Ala in the compound is not polar nor ionizable but the presence of Lys makes the polypeptide to be soluble.
(b) (Glu)zo is a polar peptide, therefore soluble peptides while both the combination of (Phe-Met)3 gives polypeptides that are not polar therefore not soluble.
(c) In poypeptide of (Ala-Asp-Gly)s, the R group on the side chain of both Ala and Gly are neither polar nor ionizable therefore cannot be soluble even though Asp( which at PH 3 can partially be protonated and partially deprotonated to make it soluble) is present in the polypeptide. Therefore the polypeptide of Ala-Asp-Gly is not soluble compared to Asn- Ser-His, where Asn has polar covalent bond which can interact with water, His which at pH 6 will be half protonated and half deprotonated making the substance to react with water and also Ser is a soluble polypeptide too.
(d) Also between (Ala- Ser-Gly) and ( Asn- Ser-His), polypeptide with (Asn-Ser-His) will be considered soluble because Ala and Gly have R groups that neither polar nor ionizable though Ser is soluble but common to both substances, its influence will not be effective and (His) is a soluble which at pH 6 get partially protonated and deprotonated.
Answer:
four amino acids are produced from 15 nucleotide sequence which includes last three nucleotides for stop codon.
Explanation:
Every three nucleotides makes one codons that encodes one amino acid. As in this question there are only 15 nucleotides and each 3 nucleotides makes one codon hence only 4 amino acids are encoded by this sequence. Last three nucleotides for stop codon which does not encodes an amino acid.
Answer is 15 nucleotide sequence encodes 4 amino acids and one stop codon
The strawberry preserves heterogeneous mixtures.
Homogeneous mixtures exhibit uniform composition and characteristics throughout and are called solutions. On the other hand, the heterogeneous mixtures refer to those that are not the same in composition and characteristics throughout. The heterogeneous mixtures can be colloids or suspensions.
The homogeneous mixtures comprise a single phase, on the other hand, heterogeneous mixtures comprise various phases.
