She will have 23 chromosomes in her egg cells.
Photosynthesis? Its when a plant takes in sunlight for ATP (energy).
Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
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.
