Answer:
lignified vascular tissue
Explanation:
Stems of Vascular plants are made of vascular tissues and lignin which gives it is characteristics stiffness and the ability to grow tall to access more light and air.
Water can act as either a base or an acid. Water acts as an acid by donating a hydrogen ion when it reacts with a stronger base such as sodium hydroxide. Water may also act as a base when it accepts hydrogen ion when reacting with a strong acid such as hydrochloric acid. This is based on Bronsted concept and definition of a base ( proton acceptor) and acid (proton donor). Such a compound that can act as a base and as an acid is called an amphiprotic molecule.
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms.
The most painfull effect resulting from loss of insect species globally would likely be a drop in crop pollination.
<h3>What do you mean by pollination?</h3>
Pollination is the act of moving pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, contains plants, is to create offspring for the next generation. One of the ways that plants can make offspring is by creating seeds.
Thus, option "B" is correct, The most painfull effect resulting from loss of insect species globally would likely be a drop in crop pollination.
