Answer:
cell wall, chloroplast, and one big vacuole
Explanation:
Cell wall - exterior to the cell membrane is a rigid cell wall made up of cellulose. It is freely permeable to water and solutes but prevents the cell from bursting
Chloroplast- contains green pigment, chlorophyll, which traps light used in photosynthesis.
Vacuole- filled with sap which contains sugar, salts and waste products and enclosed by tonoplast. Acts as a store for sugars and salts. Maintains the shape of the cell.
Answer:
Amount of XY or XX chromosomes in the sperm used to fertilize the egg
Explanation:
If you're female the sperm had XX chromosomes
If you're male the sperm had XY chromosomes
Question: A student makes a claim that a cell is undergoing the process of transcription. What evidence would be present to support this claim?
A) tRNA with anticondos is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotide at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
The evidence that the student have to produce as an evidence is the "RNA polymerase using the single strand of the DNA molecule as a template for mRNA production."
Explanation:
We know, that in transcription the genetic information from the DNA is copied into RNA for production of the proteins. According to various research methods, to know whether the cell is going through the transcription, a student can use the bacteriophage coat protein, which must have labelled with the fluorescent protein for studying it under microscope. After, this has been done, in the right location stem loop present, the RNA will be seen initiating of the elongation step, hence the transcription site will be more visible when the coat protein binds to the new RNA, which has happened in the transcription site. We can know see the transcription as fluorescent which will help the student to determine the process of transcription in the cell. Presence of promoters are important to demonstrate the process.

</span><span>Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells.

12 chromosomes for diploid becomes 6 for the sperm cell
