Answer:
Medulla oblongata
Explanation:
Medulla oblongata is the part of hindbrain and have three vital centers located in it. The vital centers present in medulla are:
1. Cardiac center
2. respiratory center
3. and vasomotor center.
The cardiac center is also known as cardio inhibitory center and is involved in regulation of heart beat. The basic rhythm of breathing is under regulation of respiratory center while diameter of blood vessels is regulated by vasomotor center.
Hypertonic is when the solution has a high concentration (high osmolarity), hypotonic is when the solution has a low concentration (low osmolarity) and isotonic is when the conditions are equal (same osmolarity). When in an hypotonic environment, a cell will take in water, causing it to swell
Answer:
(E) seedless vascular plant
Explanation:
Seedless vascular plants, compared to some other kinds of plants, reproduce and disperse through unicellular spores instead of seed. They possess vascular tissues but do not possess seed or flower.
The life cycle of the seedless vascular plant is characterized by alternation between the diploid sporophyte and haploid gametophyte. The haploid gametophyte is small, but still independent while the diploid sporophyte is is large and long- lived, it is the dominant phase of the life cycle.
Examples of seedless vascular plants are horsetails and ferns
