Answer:The cells that produce hair contain a lot of ROUGH ENDOPLASMIC RETICULUM , while the cells that produce the oils that coat the hair contain a lot of SMOOTH ENDOPLASMIC RETICULUM.

Explanation: ROUGH ENDOPLASMIC RETICULUM or  RER is a cisternae organelle that have two faces: the cytosolic face and the nucleus face. The cytosolic face is studded with ribosomes that are responsible for synthesizing proteins, a process known as translation. In the cells that produce hair, keratinocytes, the main protein synthesized is keratin.

SMOOTH ENDOPLASMIC RETICULUM is an organelle that lacks ribosomes and the function is related to lipid synthesis, different case that proteins synthesis. Specialized cells located in the SER (smooth endoplasmic reticulum) produces the oils that coat the hair called sebum to lubricate the hair. These cells secrete the sebum in an holocrine way. The composition of the sebum is made of triglycerides, wax esters, squalene.

Answer:

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).

Which of these is an disadvantage of multicellular organisms?
Softa [21]

Multicellular organisms require a lot of energy and resources to survive.

Unicellular organisms, on the other hand, require just the basic necessities. On top of that, unicellular organisms don't require a long time to reproduce as multicellular organisms do.

Thus, multicellular organisms are at a disadvantage because they require more energy, sources, and essentially time.

Hope this helps!

Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of
alexandr1967 [171]

Answer:

True.

Explanation:

Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.
