Biology DAC Review

Use this review to prepare yourself for the upcoming District Assessment


Evolution and natural selection

Evolution and Natural Selection

  • Why is Geographic Isolation so important to the process of natural selection?

  • Explain the process of Speciation

  • What does it mean to have a common ancestor?

  • Genetics problem and Natural Selection

  • What is the difference between Homologous and Analogous structures?


Classification

Classification

  • If two specific organisms are very similar genetically…should they be classified together? Explain!

  • Scientific name problem


Scientific name problem

Scientific Name Problem

  • 1. Dogs (Canisfamiliaris) are most closely related genetically to which of the following organisms?

  • A African hunting dog (Lycaonpictus)

  • B Gray wolf (Canis lupus)

  • C Grizzly bear (Ursusarctos)

  • D Domestic cat (Feliscatus)

  • 2. The bullfrog, Ranacatesbeiana, is most closely related to the —

  • F spotted chorus frog, Pseudacrisclarki

  • G Asian flying frog, Polypedatesleucomystax

  • H northern leopard frog, Ranapipiens

  • J African bullfrog, Pyxicephalusadspersus


Scientific name problem2

Mendelian genetics

Mendelian Genetics

  • Define in your own words

    • Incomplete Dominance

    • Codominance

    • Sex Linked

    • Dominant

    • Recessive


Mendelian genetics1

Mendelian Genetics

What trait will most likely be observed in all offspring of

the above set of parents? Show your punnett square!!!

A Green feathers

B Yellow feathers

C Long beak

D Short beak


Mendelian genetics co dominance

If you mix white paint (W) with

red paint (R) you would get

Pink paint…right? Show a punnett

square that proves this!


Experimental design

Experimental Design

A student placed a disk of filter paper in each of the following solutions: disinfectant 1, disinfectant 2, disinfectant 3, and distilled water. While the four disks were soaking in their respective solutions, she streaked a sterile nutrient agar dish with a culture of E. coli bacteria. Then, she placed each disk carefully onto the nutrient agar dish, placed the lid on the dish, taped it shut, and incubated the dish at 37ºC for several days. Figure 19-4 shows how the nutrient agar dish looked on Day 1 and Day 4.
