Answer:
After a cell was treated with a certain chemical, the ribosomes stopped functioning. The cell activity immediately affected by this change in ribosome function is protein synthesis.
Explanation:
The basic structural units of all living things are known as cells. Inside the cells, specialized structures called ribosomes are present, which synthesize proteins. The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation.
The transcription process takes place in nucleus, where the information from a DNA strand is copied into a single stranded messenger RNA (mRNA) molecule using RNA polymerase enzyme. During the ending of transcription, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the ribosome, translation occurs where the genetic code in mRNA is read and protein is synthesized. These proteins are used by cells to perform important functions such as repairing cellular damage, maintain cellular structure, create hormones, cell division etc.
Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells
The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
