Answer:
In roots, the vascular tissues, i.e., xylem and phloem, are found in the central vascular cylinder, while in stems these tissues are dispersed throughout the stem, generally arranged as a ring towards the outside of the stem (epidermis)
Explanation:
Vascular plants have two different transport tissues: xylem and phloem. The xylem transports water from roots to stems and leaves, while the phloem transports food (i.e. dissolved sugars) from the leaves to all parts of the plant. In roots, vascular tissues form a central core in order to withstand stretching forces. Moreover, in stems, vascular tissues are dispersed (generally concentrated towards the epidermis), in an arrangement that enables them to resist compression and bending forces.
Answer:
E. Fecal coliforms will likely contain enzymes to counteract toxic oxygen forms.
D. Fecal coliforms will need to acquire trace elements for growth in the lake environment.
C. The lake environment will support the growth of facultative anaerobes.
Explanation:
For the growth and multiplication of bacteria following factors are important required in their environment;
- trace elements
- oxygen
- nutrients
"The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms. ... This set of reactions is also called carbon fixation. The key enzyme of the cycle is called RuBisCO."
d) Meiosis occurs often because it allows growth and repair of body tissues in multicellular organisms.
