<span>
Tracheids and vessel elements are the main components of xylem witch have a function to transport water. Those are elongated dead cells at maturity (without protoplast) with a thick, strengthened cellulose cell wall and a hollow lumen. Even though they are dead they still maintain a function, because are being protected by surrounding living cells.</span>
Answer:
B. Decrease to its carrying capacity
Explanation:
Goby fish feed over algae for their survival and growth but if 50% of algae in the ocean decreases then the population of goby fish will decrease to its carrying capacity.
This is so because then the goby fish will be dependent on the left number of algae and maximum population size will depend on the rest 50% of food or algae available.
Hence, the correct answer is "B. Decrease to its carrying capacity".
<span>If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.</span>
