D is the right answer. Quantitative data is information that is conducted from measurements and written down with numbers.I hope i helped you!
Answer:
Please see below
Explanation:
These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.
The skin, mucous membranes, and endothelia throughout the body serve as physical barriers that prevent microbes from reaching potential sites of infection. Tight cell junctions in these tissues prevent microbes from passing through.
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
