Sunny_sXe [5.5K]
<h2>Inflation </h2>

Explanation:

During inflation, air moves in the lungs when the air pressure within the alveolar spaces falls below the atmospheric pressure

The forces that normally cause changes in volume of the chest and lungs arises not only from muscle contraction but from the elastic properties of both the lung and the chest

The force required to maintain inflation of the lung and to cause airflow is provided by the chest and diaphragm (the muscular partition between chest and abdomen), which are in turn stretched inward by the pull of the lungs

Hence during lung inflation, the lungs cling to the internal surface of the chest wall as it expands

Explain how salinity and temperature affect water density and how the salinity of the oceans can be both increased and decreased
finlep [7]

Answer:

Salinity is the <em><u>salt concentration</u></em> in water. Oceans salinity and temperature affect density of water, Higher the salinity denser the water and Lower the temperature denser the water.

Explanation:

As we go down in the ocean , temperature goes down and denser the water.

Less dense water will be on top and higher the density will be on bottom. Warmer water will be on top.

Salinity <em> increased</em> in ocean on evaporation of sea water and formation of ice in water. Weathering of rocks , formation of soil also add minerals and salt in ocean.

Melting of snow, ice in sea, addition of river freshwater and precipitation of rain <em>decrease </em>the salinity of ocean.

the frogs tongue is anchored in the very front opposite to the orientation and anchoring of humans why is that?
Mice21 [21]
Frog's tongues are attached to the front of their mouths rather than at the back like humans. When a frog catches an insect it throws its sticky tongue out of it's mouth and wraps it around its prey. The frog's tongue then snaps back and throws the food down its throat.
