Hair Matrix
The hair matrix is wrapped almost totally around the papilla. It is a collection of cells, primarily comprising of epithelial cells and some pigment-producing cells called melanocytes. The continuous division of cells in the hair matrix forms the hair shaft (the strands of hair that we actually see) and the inner and outer root sheaths of the hair.
Answer:
LONG-LIVED DESERT SHRUBS EXHIBIT INFREQUENT, EPISODIC RECRUITMENT FROM SEED. IN SPITE OF THIS LONG TIME SCALE, SELECTION ON LIFE HISTORY ATTRIBUTES THAT AFFECT SEEDING RECRUITMENT SHOULD BE STRONG.
Explanation:
The cell would die as it must maintain homeostasis in order to function.
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
