1. Why are the onion root tip and whitefish blastula useful tissues for studying cell division? 2. What other structures in a plant or animals might be useful for studying mitosis? 3. If a cell has 32 chromosomes when it first enters interphase, how many chromosomes will it have when it starts prophase? 4. What is the purpose of mitosis? In other words, how is it useful for life? 5. How is mitosis different from cytokinesis? 6. How do plant...

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...

Part C: Mitosis the body nceds more cells (for growth or repair), the way to produce new ones is for existing cells to divide. The series of events that leads to cell division is called the cell cycle. The cell cycle has distinct phases-most of the time, a cell is in itself is divided into three phases: Gl, in which a cell is engaged in the normal activity of thar cell making protcin, gencrating ATT, etc.l; S, the phase when...

Can anyone help me with this? Thank you.
Lab 13. Mitosis and Meiosis Purpose The purpose of this lab is to understand the process of mitosis and melosis in animal and plant cells. Learning Objectives After completing this lab, you will be able to: 1. Describe the stages of mitosis. 2. Identify the stages of mitosis in an onion root or whitefish blastula using a light microscope. 3. Describe how cytokinesis differs in plant vs. animal cells. 4. Name and...

answer this pls asap
PART 1: How Long Do Cells Spend in Each stage of Mitosis? In this activity, you will be presented with cells from the tip of an onion root. You will classify each cell based on what phase it is in. At the end you will count up the cells found in each phase and use those numbers to predict how much time a dividing cell spends in each phase. You can base your calculation on a...

In animal cells, a characteristic feature during cytokinesis is the formation of something called the (26), while in plants a characteristic feature that forms is the Prokaryotes do not have a nucleus, and so they do not perform their chromosome and divide with a process known as (28), and simply duplicate Different cells divide at different rates because they vary with respect to regulation of their (30) .

Part II: Ann’s doctor is worried enough to send her to a breast cancer specialist, just to be safe. Ann makes an appointment and is referred for a mammogram, which will image the soft tissue in the breast. After the mammogram and an exam, she meets with the surgeon, Dr. Hernandez. Dr. Hernandez is also concerned, as she felt and has images from the mammogram of a small tumor. She recommends a biopsy of the tumor as soon as possible....
