is a Disaccharide molecule it is to monosccarides connected by a phosphodister bond. one example would be Maltose
hope this helps!!!!
Explanation:
- stomata
1 (a) Carbon dioxide enters stomata while water and oxygen exit, through a leaf's stomata they allow carbon dioxide in, but they also let precious water escape.
1 (b) Plants use carbon dioxide, oxygen and water in photosynthesis
2 Water is passively transported into the roots and then into the xylem. The forces of cohesion and adhesion cause the water molecules to form a column in the xylem
2(a)Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant
The following events will be catastrophic to an ecosystem:
1. Al volcanic eruption
2. An oil spill and
3. The introduction of a species that reproduce quickly.
A volcanic eruption will disrupt both the plants and the animal activities in a particular ecosystem and lead to loss of habitation. Depending on the extent of the volcanic eruption, a whole ecosystem can be completely wipe out. An oil spill is very poisonous to aquatic ecosystem and it leads to the death of the organisms that live in the water. Introducing a specie that reproduce quickly into an ecosystem will lead to fast taking over of the ecosystem by that specie to the detriment of other species.
The DNA should be the one storing information in a cell because it contains all of your needed features of being you.
