Dihybrid Cross Practice Problems

Directions: Complete the following Dihybrid Cross problems. Identify the gametes from each parent. Complete a Punnett Square for the cross Identify the genotypes and phenotypes for the potential offspring. Find the phenotypic ratio for the potential offspring.

Plant Taxonomy: Summary & Characteristics

Defining Characteristics of the Plant Kingdom: Multicellular Terrestrial Embryophytes Photosynthetic (almost all) Eukaryotic 4 Major Groups 1.     Non-Vascular Plants (Bryophytes and Friends) No vascular tissue – therefore must rely on surrounding moisture and osmosis to move fluids through their bodies. Small in stature, and simplistic – NO organs (roots, leaves, stems) (Rhizoids = root-like structures…

Ventricles and Meninges

Ventricles= expansions of the brain’s central cavity Filled with CSF, lined with ependymal cells Continuous with each other, central canal, and spinal cord 1st/2nd= paired lateral ventricles (lie in cerebral hemispheres) [separated by septum pellucidum– transparent wall] 3rd ventricle lies within diencephalon [connected to each lateral ventricles by interventricular foreamen] In midbrain is central cavity…

Diencephalon: Thalamus, Hypothalamus, Epithalamus

Diencephalon: forms central core of forebrain, surrounded by cerebral hemispheres. Made of 3 paired structures: 1) thalamus, hypothalamus, and epithalamus. Thalamus: egg-shaped (known as inner room) has midline connection called interthalamic adhesion ***EVERY part of the brain that communicated with the cerebral cortex must relay its signals through a nucleus of the thalamus. Hypothalamus: inferior…
