The correct answers are:

• Liver cells are abundant in SER.

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

Explanation:

Winds are caused by low and high pressure zones, mainly due to temperature differences of atmospheric air in different regions. Air moves from high to low-pressure zones causing winds.

Local winds, as the name suggests, are winds due to regional temperature differences. An example is sea breeze caused by temperature differences over land and sea in the region.

Global winds, on the other hand, are caused by large pressure systems across the planet. These are mainly caused by differences in how the sunlight ‘hits’ the planet at different latitudes – due to earth’s spherical nature- causing differential heating of the earth. These winds travel great distances causing trade winds.
