Answer:
The skin helps in the cooling of the body,when there is exess temperature in the body,the skin reduce it and changes it in the form of sweat and also skin acts as a passage of the sweats.
Answer:
Dissolved oxygen concentrations are constantly affected by diffusion and aeration, photosynthesis, respiration and decomposition. While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³.
Explanation:
A narrow valley is formed. Hope this helps :)
Answer:
1. Wind moves horizontally because of differences in air pressure. These differences in air pressure are a result of __differential______ heating of earth’s atmosphere from the _sun____.
2:This pressure moves from an area of __high___pressure to an area of__low___ pressure, creating the wind.
Explanation:
The sun rays ‘hit’ the earth's surface with increased obliquity with increasing latitude. In addition, the density of the sun rays per sq meter also decreases with increasing latitude. This is all due to the spherical nature of the earth.
However, there are also local differences that cause the earth's surface to heat differentially such as terrain and cloud cover, etc. This creates regions of warmer air mass (low-pressure zones) and cooler air mass(high-pressure zones). These differences cause winds because of air rushes from high to low-pressure zones due to differences in air masses’ temperature-related densities.

Explanation:
Integrins are principal receptors that bind to the extracellular matrix. They act as transmembrane linkers to link extracellular matrix and the actin cytoskeleton
The adhesive activity of integrins is regulated through two ways –
a) Within the cell
b) Out side the cell by extracellular divalent cations i.e Ca2+ or Mg2+. This shows that there is divalent-cation-binding domains in the extracellular part of the α and β subunits which affects both affinity and the specificity of the ligands to which the integrin binds
