Two genetically identical daughter cells are formed. d Crossing over occurs during prophase e. It consists of two nuclear divisions. Quession 15 How does a nucleus in G2 difler from a nucleus in G17 Select one a. DNA synthesis occurs only in G1 phase. b Inactive cells are arrested only in G2...

5. For this part of the lab you will be observing a whitefish
blastula under the microscope. A blastula is a developmental stage
in many animals. It occurs shortly after fertilization and the
formation of the zygote. It is the “ball of cells” stage of
development, where cells are dividing rapidly to form the
multicellular organism. Note: In this simulation early and late
prophase are combined into one stage: prophase. 1. Go to the
Virtual Microscope (Links to an external...

It sort of looks like the number or to this cell is two buiging ends. It sort of looks like the number 81 You realize that A) undergoing cytokinesis. C) in the G1 phase of interphase.

Draw the slide under 400X. Indicate the cell type, magnification, and estimate the cell size. 14. Elodea 1. Prepare a wet mount of an Elodea leaf (Anarcharis). You will use one glass slide and cover slip for this entire lab. After preparing each slide, remove the specimen and throw it into the trash. Wash the slide in the sink. Dry the slide with a paper towel very carefully and pat the cover slip dry so that the plastic does not...

Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, homologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...
