1. rough endoplasmic reticulum

2. smooth endoplasmic reticulum

Explanation:

Hair, which is made up of cells called KERATINOCYTES, is primarily made up of a protein called KERATIN. Cells in every part of the body contains organnelles that performs certain functions. Based on the asked question, we'll be looking at two of these organnelles; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum.

Rough Endoplasmic Reticulum is a cellular organnelle that is directly involved in the production of proteins in a cell due to the attachment of ribosomes (site of protein synthesis) to it. Hence, RER is responsible for the production of matured proteins in a cell. The Smooth Endoplasmic Reticulum, on the other hand, is involved in the synthesis of lipids (fats and oils) in a cell.

Since the hair is basically made up of keratin protein, it is just sensible that the cells responsible for the production of hair (keratinocytes) will be rich in the organnelles that produces proteins (Rough Endoplasmic Reticulum) while the cells that produces the oily substances that coat the hair will be rich in the organnelle that synthesizes oil (Smooth Endoplasmic Reticulum).

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
