1) the internal balance within an organism is called
a)physiology
b)homeostasis
c) thermoregulation
d) hypothalamus
2) which organism maintain a constant body temperature despite temperature changes in the environment?
a)a frog
b)maple tree
c)goldfish
d)human
3)when leaf has plenty of water
a) the guard cells swell and the stomates open
b)the guard cells swell and the stomates close
c)the guard cell lose pressure and the stomates open
d)the guard cells lose pressure and the stomates close

1. b. homeostasis: The internal balance of heat within an organism is maintained by the process of homeostasis. It is the ability of the organism to maintain the internal body temperature with respect to the changes that occur in the external environment.

2.d) human: The human beings are capable for maintaining the internal temperature due to homeostasis because they exhibit fat which allows them to maintain the internal heat.

3.c) the guard cell lose pressure and the stomata open: The stomata are small pores present on the underside of the leaf surface these are important for exchange of gases and water to the external environment. The water is lost by the stomata of the leaf during transpiration. When the plant requires to remove excess of water from the plant body it is evaporated from the stomata through transpiration.  

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
