<u>(B) wheat</u>
Explanation:
- Wheat is an <u>anemophilous</u> plant (form of pollination by which wind distributes pollen)
- They lack petals and sepals (outer whorls of the flower)
- The female plants consist of an ovary (female reproductive part) from which two styles (connecting stigma and ovary) arise
- The feathery stigma catches the pollen and sends it to the ovary for fertilization
Answer:
Explanation:
Velocity of plane relative to ground V_pg = ?
Given the velocity in vector form ,
velocity of plane relative to air V_pw = 120 cos30 i + 120sin30j
V_wg = 60 i
V_pg = V_pw +V_wg
= 120 cos30 i + 120sin30j + 60i
= 164 i + 60 j
