Hello can you help me out here!

1) They are a pipe like consisting of specialised cells. They transport substances and form a two way traffic in plants
a) Xylem tissue
b) phloem tissue
c) Root hair
d) Vascular tissue

B

Explanation:

because Phloem tissue consists of a group of specialized cells. Sieve tubes are elongated tubular conducting channels of phloem through which food is transported. The contents of phloem can move in the upward as well as in the downward direction. Therefore, they form two-way traffic in plants.

Phloem

Explanation:

Xylem transports water by action of trandpiriation pull, capillary action and root pressure. Phloem consists of sieve tubes and companion cells. The phloem is made of tubes and cells basically.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
