Topic 1 Assignment The three topics that I have chosen to examine for the first assignment are: reproduction, adaptation and homeostasis. All eight the components that are necessary to be termed a living entity are worthwhile, but these are the three that most peaked my interest in which I wanted to learn more about the process in answering necessary assignment questions. Reproduction Every living thing has to be able to reproduce in order to maintain being a living thing. Every living organism, eventually dies. If there is no reproduction or offspring, that species, would eventually die out or become extinct. Examples of organisms that reproduce are everywhere around us in the world, from plants and animals to parasites and red blood cells.

Bio104 Laboratory ? Student?s Guide John Jay College, C.U.N.Y Lab #5 ? Page 1 Lab #5: Green Algae, Fungi, and Lichens I. More Protista a. Continuing from last week, this will lab will explore the Domain of Eukarya. Remember that the group of organisms commonly called ?protists? is not an actual taxon ? it?s a collection of many phyla. b. Some of the protists that we will examine today are the green algae. These single-celled organisms have a common ancestor with plants, and present-day algae share many features with the ancestor of plants. All green algae are technically unicellular organisms, but some form colonies with an impressive degree of organization.

Bio104 Laboratory ? Student?s Guide John Jay College, C.U.N.Y Lab #6 ? Page 1 Lab #6: Evolution of Land Plants I. Introduction a. Last week, we learned about several types of green algae and explored their evolution from solitary single-celled organisms through colonialism and into multicellularity. Although green algae are protists, green algae and land plants share a common ancestor and have many shared features. Both are Eukaryotes and both have chloroplasts that are strikingly similar. b. However, plants have diverged considerably from algae. The two most striking differences are that plants have evolved life cycles that are very distinct from that of protists, and that nearly

Cell Cycle cancer is the cell cycle going out of control most animal species are diploid cell division is a part of the cell cycle DNA is just the one molecule when you see chromosomes in a condensed state, DNA replication has already occurred cell division time varies according to cell type, but takes about 24h on average Meiosis ?How does meiosis affect genetic content?? asexual reproduction is quick and efficient transition to haploid occurs at anaphase II chiasma: crossing over 2n: number of possible chromosomal recombinations Genetics Problems note ratio - see if epistasis is occurring outside members of the genetic line can bring mutated alleles for carrier questions, discard affected genotypes from Punnett square (setting a limit)

Chapter 47: Animal Development Overview ?It is difficult to imagine that each of us began life as a single cell called a zygote ?A human embryo at about 6?8 weeks after conception shows development of distinctive features 1. An organism?s development is controlled by the genome of the zygote as well as by molecules from the mother that are in the cytoplasm of the egg. What are these proteins and RNAs called? ?Development is determined by the zygote?s genome and molecules in the egg called cytoplasmic determinants 2. What is cell differentiation? ?Cell differentiation is the specialization of cells 3. How do cytoplasmic determinants affect cell differentiation? ?Structure and function 4. What is morphogenesis? ?Morphogenesis is the process by which an animal takes shape

Maia Regman Mrs. Magnan Biology Honors 22 March 2014 Understanding Miscarriage Possibly the most taboo topic of childbirth is miscarriage. It is rarely spoken about because it is such a sensitive topic for women and their partners. Miscarriage is very common despite it not being represented that way.
