-Lipids do not contain monomers, which repeat to make polymers.
- A cell is unable to take up or make sugars.
Answer:
y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Explanation:
30 chromosomes
Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.
From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.
Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.
From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.
DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.
Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.
Animal cell do not have cell walls
25 degrees Celsius, as this is the highest point on the graph which means that the oxygen flow is optimal at this temp. Since oxygen is a product of photosynthesis, if more is flowing at 25 degree, more photosynthesis is happening.
When a protein is synthesized on fixed ribosomes, it is threaded into the lumen of endoplasmic reticulum (ER).
Every eukaryotic cell has an endoplasmic reticulum (ER). The ER is arranged systematically into a web-like maze of radiating tubules and flattened sacs stretching all over the cytosol.
The tubules and sacs are all believed to interlink, so that the ER membrane forms an extended sheet bordering a single internal space. This highly complicated space is known as the ER lumen.
The ER traps selected proteins from the cytosol during their synthesis.
The two kinds of proteins include:-
- transmembrane proteins, which are only partially moved across the ER membrane and are submerged in it, and
- water-soluble proteins, which are completely transported across the ER membrane and are discharged into the ER lumen.
