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).

What logical scientific inference can be drawn from the observation that many different species have homologous structures?
Alexus [3.1K]
<h2>Answer:</h2>

Option C) All species with similar anatomical structures are related.

<h2>Explanation:</h2>
  • Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
  • All species with similar anatomical structures which means they have  homologous structures and are related as they have evolved from a common ancestor.
  • Homologous structures shows divergent evolution.

Result: Option C is the correct scientific inference for homologous structures.

In a study of the raw materials used for photosynthesis, what two kinds of molecules would be studied?
il63 [147K]
In a study of the raw materials used for photosynthesis, the two molecules that would be studied are carbon dioxide and water. This is because they are the reactants of the process. Without these molecules the process of photosynthesis cannot happen.
