<h3><u>Answer;</u></h3>
Climax-Pattern Theory
<h3><u>Explanation;</u></h3>
- The Climax Pattern Theory emphasizes that a natural community is adapted to the whole pattern of environmental factors in which it exists.
- In addition to climatic factors, e.g. wind, there are a whole range of edaphic factors, fire, and biotic factors, including grazing, disease and mutualistic and competitive interactions.
- The Climax Pattern Theory allows a continuity of climax types, varying gradually along environmental gradients and not neatly packaged into discrete climax types.

The process of <u><em>meiosis </em></u>increases genetic variability as it produces gametes for sexual reproduction
Explanation:
More complex organisms, including humans, produce specialized sex cells (gametes) that carry half of the genetic information, then combine these to form new organisms. The process that produces gametes is called meiosis. During meiosis, homologous chromosomes (1 from each parent) pair along their lengths.
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.
