Answer:
a is right I think so...........
Answer:
The correct answer is option
(B) Both Statement and Statement II are true.
Explanation:
Most marine invertebrates are osmoconformers, although their ionic arrangement may be distinct from that of seawater. Osmoregulatory tightly regulate their body osmolarity, which still remains constant, and exists more familiar in the animal kingdom.
All birds and mammals and a very rare lower vertebrate and invertebrate species exist certainly qualified for such regulation (thermoregulation and osmoregulation).
Some organisms can sustain homeostasis by physiological (sometimes behavioral also) points which ensure constant body temperature, constant osmotic concentration, etc.
An overwhelming majority (99 percent) of creatures and nearly all plants cannot maintain a constant internal environment.
Their body temperature modifications with the ambient temperature. In aquatic creatures, the osmotic concentration of the body fluids modifications with that of the ambient air, and water osmotic concentration. These animals and plants are just conformers.
Thermoregulation exists actively expensive for numerous organisms. This exists especially true for small animals like shrews and hummingbirds.
The correct answer is option (B) Both Statement and Statement II are true.
