- 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.

Hihi!
There are seven characteristics of living things: movement, breathing or respiration, excretion, growth, sensitivity, and reproduction! But sadly as for non-living things they lack most of these things. Their characteristics are that <span>they lack the </span>capability<span> for </span>growth<span>, </span>reproduction, respiration<span>, </span>metabolism<span>, and </span>movement<span>. They also cannot </span><span>respond to a stimuli and they also cannot</span><span> evolve and adapt to their environment. Isn't that kind of sad?
</span>
I hope I helped!

Atlantic cod is a benthopelagic fish that is consumed primarily by humans. These are commercially known as codling. From the given choices, legal regulations and increasing reproductive capacity are both beneficial to the population of the cod. The water temperature is also likely to affect the population but not as much as overfishing does. Therefore, the answer is the first choice.
Yes if have them in the refrigerator for a long time and then take them out and leave them on the counter for a good 2 days
