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.
<h2>Ecological Footprint - Option C</h2>
An ecological footprint is determined by measuring the rate of water used. The Ecological Footprint is determined by following how much biologically prolific field it needs to consume a population's carbon dioxide radiations and to produce all the means it absorbs.
A country's consumption is measured by summing imports to and deducting exports from its nationwide generation.
The answer is B. A dependent variable is one that varies according to the modulated independent variable. In this case, the independent variable is A -‘The amount of Drug x given to the mice’ since it is the one that is being controlled in the experiment.
This should be True
Seafood Watch has had an immense influence on decisions regarding illegal fishing practices and has helped design sustainable seafood environments due to their lists of seafood that should be eaten without worries.
