Answer:
positive affects and negative
Explanation:
Habitat Destruction. Virtually all Ocean habitats have been affected in some way via drilling or mining, dredging for aggregates for concrete and other building materials, destructive anchoring, removal of corals and land “reclamation”.
Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.
During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent the leaves from taking in too much water during rainfall.
Answer:
Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
I would say photosynthetic bacteria are the most important, because if they disappeared most of the oxygen in the atmosphere wouldnt be here and complex life like humans wouldnt exist
