Xylem tissue is composed of vessel cells and tracheids. Vessel cells lack end walls and join to form long tubes. Tracheids are slender cells with over lapping ends. This structure enables it to give support to the tree as well as moves water to aerial parts.

iii) In Phosphoenolpyruvate, initial incorporation of 14^C occurs at C-3
iv) In Acetyl-CoA, initial incorporation of 14^C occurs at C-2 (methyl group)
v) In Citrate, initial incorporation of 14^C occurs at C-4
vi) In a-ketoglutarate, initial incorporation of 14^C occurs at C-4
vii) in Oxaloacetate, initial incorporation of 14^C occurs at Equally distributed in C-2 and C-3.
Answer:
Pressure gradients, the rotation of the earth, and friction are three primary variables that influence the wind. Atmospheric pressure gradients are the ultimate source of wind. The wind blows from high-pressure zones to low-pressure areas.

B.
Viruses are classified as biological agents instead of a living things, $& they are only made of genetic material.
The correct answer is B. <span>When a bar magnet is cut in half, each half has a north pole and a south pole.
So, Candice learned that every magnet has two magnetic poles. This means that when you cut a whole magnet into two parts, you will get two new magnets. According to her observation, each of these two new magnets are going to have a north pole and a south pole.</span>
