Answer:
Perspiration provides homeostasis to the internal condition of temperature balance.
Explanation:
Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.
The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.
The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.
The other options are not correct because:
- <u><em>Water and electrolyte balance</em></u><em> is done at the renal level.
</em>
- <em>The </em><u><em>energy balance</em></u><em> depends on the food intake and the amount of energy used.</em>
Answer:
O sinkholes, caves, and hot springs chemical and physical actions of groundwater.
Explanation:
Sinkholes, caves, and hot springs are formed from the actions of groundwater. The rock is made up of lime below the surface of sinkholes. These lime react with underground water and dissolve it which soften the rock and causes sinkholes. Caves are also formed when the water dissolve the limestone present in the rocks of the cave and slowly the degradation of rock will occur and caves are formed. Hot springs are formed when the groundwater is heated by the magma of the earth crust.

Answer:
B. 26amu
Explanation:
The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.
The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.
Hence, A = Z + N
Where A = Mass number
Z = Proton (atomic number)
N = Neutron number
In this question, N is 11 while Z is 15
Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
