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.
<u>Less reproductive </u><u>isolation </u><u>among populations that share similar </u><u>habitats</u><u>.</u>
What is habitat reproductive isolation?
- Habitat isolation is the term for when populations of a species move to a new habitat and settle in an area where they no longer overlap with other populations of the same species.
- When reproduction with the parent species stops, a new group emerges that is genetically and reproductively independent.
What factors affect reproductive isolation?
- The members of different species will be reproductively isolated by any factor that prevents potentially viable individuals from coming together.
- Different habitats, physical barriers, and a variation in the timing of sexual development or flowering are examples of the different types of barriers that can result in isolation.

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
