Answer:
50 visible chromosomes and replicated.
Explanation:
- Diploid number 50
- Haploid number 25
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
Interphase is composed of stages G1, S, and G2. During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
Meiosis occurs after the interphase is over.
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
At the beginning of prophase 1, DNI is condensed in a well-defined chromosome formed by two sister chromatids joined by a centromere. Each chromosome carefully pairs with its homologous chromosome. Homologous chromosomes aline together to make the crossing-over possible, the stage where they interchange their parts.
The whole set of chromosomes is present in prophase 1. The reduction occurs later.
So if the germ cell has 50 chromosomes, the same 50 will be visible during prophase 1. DNA has already been replicated during the S stage of interphase.
Answer: increase of a blood pressure can cause the body to increase its temperature
Explanation:
Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
<span>B. Stamen is the correct answer. It is the only part that
belongs to the male flower. Stamen has anther which is a saclike structure where
pollens are developed and filaments which act as the part of the flower which
transports the pollen. Flowers usually has the same petals as their number of
stamen. Various flowering plants have different types of stamen. Some are
attached to the petals and some are not. When female flowers receive the
pollens from the male flower’s stamen, the flowers reproduce.</span>
Garments cannot be made out of coconut fibre because they are very rough and are unable to be sew as it also the break very easily.
The coco fiber or coir is a fiber extracted from the husk of a coconut and is often used to make floor or door mats, mattresses and brushes. It is hard that is only suitable in making upholstery padding and sacking.
