1. Three (3) eggs are boiled and all weigh 2g. The eggs are placed in a 15% solution ofNaCI and reweighed after 30 minutes. Tell me which egg was isotonic to the NaClsolution, which egg was hypotonic to the NaCI solution, and which egg was hypertonic tothe NaCl solution and explain how you know this. - Egg 1 = 2.5 grams hypertonic, Egg 2 = 2 grams isotonic, Egg 3 = 1.8 grams hypotonic. 5 properties of life - cellular organization, metabolism, homeostasis, growth and reproduction, heredity ...

Primavera Biology B Unit 1: Genetics Questions and Answers 100% Pass CHECKPOINT 01 Some people have dimples; other people do not. Having dimples is dominant over not having dimples. If the allele for having dimples is represented with the letter D, what allele combinations can result in having dimples? DD, Dd Which statement is true about model organisms? They help scientists understand biological processes. A pea plant that is tall has a dominant trait. Which statements are true about the...

Allele - alternative form of a gene (one member of a pair) located at a specific position on a specific chromosome (a letter) Codominance - occurs when BOTH alleles of a gene are expressed in an individual (ex. Black + White = Black & White Speckled) Dihybrid cross - a two-trait cross (ex. color & shape) Dominant Allele - an allele that produces the same phenotype whether its paired allele is identical or different (capital letter) F1 Generation - first filial generation is the generation...

binary fission - asexual, usually in prokaryotes origin (of replication) - bidirectional (replication AND separation together) homologous chromosome (homologue) - one from mom, one from dad; similar not identical; same alleles in the same order chromatid; sister chromatid - two IDENTICAL halves of a single replicated eukaryotic chromosome histone - proteins that have DNA wrapped around them in the *nucleosome* structure nucleosome - 147nt of DNA wrapped around a core of 8 histone proteins ...
