Answer:
(B)
Explanation:
Translation will not occur in the cultured cells, because mRNA will be degraded at a greater rate than normal.
The reason of degradation is that scientist mutated the gene in eukaryotic cell which means translation will only occur in eukaryotic cell not in cultured cell.
Answer:
Earthquake occur in the sea of Indonesia instead on the land.
Explanation:
The earthquake in Indonesia have been so less deadly than those in India or Iran, even though it's magnitude was greater than both of them because the earthquake occurs in the sea of Indonesia which is far from the Indonesian land while on the other hand, the earthquake occur on the the land in India and Iran not on the sea which is more deadly as compared to Indonesia even its lower magnitude.
- Xylem contains tracheids, vessels, xylem parenchyma and xylem fibre.
- Tracheids: They are elongated, tubular dead cells with tapering end walls.
- Vessels: These are also known as trachea. They are elongated, tubular dead cells. They are joined to each other by end to end forming a continuous pipe. The cells are thick and lignified.
- Xylem parenchyma: They are also called wood parenchyma. This is the only living tissue of xylem.
- Xylem fibre: They are dead cells with thick walled fibre.
- Phloem consists of sieve tubes, companion cells, phloem parenchyma and phloem fibres.
- Sieve tubes: These are elongated, tubular living cells arranged in a row, with their perforated end walls forming a sieve. They are non-nucleated. Their protoplasm are inter-connected through sieve plates. They possess vacuoles.
- Companion cell: They are elongated, lens-shaped cells containing dense cytoplasm and prominent nuclei. These cells maintain connection with sieve cells through pits.
- Phloem parenchyma: They are living thin walled parenchyma cells.
- Phloem fibre: They are also known as bast fibre. They are elongated fibre like sclerenchymatous dead cells with thick walls containing pits and interlocked ends. Phloem fibre are the only dead cells in phloem.
