Scavenger Hunt: 41-45

45. Dominant vs. Recessive

This picture shows a dominant gene vs. a recessive gene. Brown hair is dominant (D) over blonde hair (d).

44. Endotherm

This is a picture I took on a fishing trip this summer. It is a seagull which is also and endotherm. An endotherm is a warm-blooded animal species is one whose members maintain a constant body temperature or thermal homeostasis.

43. Cambium

Cambium is a layer of active cells that separates the xylem and the phloem. These cells produce the new xylem and phloem that are represented by the annual rings of trees. This picture is part of a tree stump.

42. Evidence of different alleles for the same trait

Alleles are either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character. Some alleles are dominant over others. My mom's eye is brown and my sister's eye is blue/gray.

41. Adaptation of a Plant

Plants have adaptations to help them survive (live and grow) in different areas. In this picture, this plant adapted to conditions of growing in between concrete.
