The xylem generally transports _, whereas the phloem transports _.

1 answer:

3 0

The answers are "water and mineral ions" and "amino acids and sucrose" respectively.

For the xylem, it usually transports water and mineral ions that are absorbed from the root hair cells up to the leaves, where photosynthesis take place. Water is one of the necessary substance for photosynthesis to take place, while different mineral ions can help the plant by for example Magnesium ions can help produce chloroplast.

While phloem transports amino acid and sucrose from the location of production (eg. Leaves by photosynthesis) to the place where it is used or stored. Plant needs these substances to generate energy for activities such as growth by for example cellular respiration. This process is called translocation.

Both of these tubes help transport substances in the plant, in order to keep the plant alive.

Anna35 [415]

Calculate the average metabolic rate of a 65-kg person who sleeps 8.0h, sits at a desk 6.0h, engages in light activity 6.0h, watches TV 2.0h, plays tennis 1.5 h, and runs 0.50h daily, If the metabolic rate for sleeping is 70 J/s, for sitting is 115 J/s, for engage in light activity is 230 J/s, for watching TV is 115 J/s, for playing tennis is 460J/s and for running is 1150 J/s.

Answer:

171.8 W

Explanation:

The Average metabolic rate can be deduced by multiplying each entity performed at a some particular hour of time with their corresponding energy, all divided by 24 hours.

Average metabolic rate = $\frac{(8.0*70)(6.0*115)(6.0*230)(2.0*115)(1.5*460)(0.5*1150)}{24}$
