Why, in the evolution of eukaryotes, might ithave been advantageous for separate organismsto become united into a single organism? Canyou describe analogous, more recently evolved,examples of intimate symbioses that function asa single integrated organism?
The fact that a prokaryote has the ability to make a new protein that is placed in the cell membrane of the mesosome is important to the process of evolution because this represents a) the mutation of a gene, b) new DNA producing a new genetic variation, c) r RNA using a new type of m RNA, d) the species having a greater degree of genetic variability, e) all are true
Tell whether the statement is true or false. 1. The endosymbiont hypothesis state that prokaryotes evolved into eukaryotic cells 2. Eukaryotes contain organelles such as mitochondria and chloroplast 3. Organisms develop by a process known as spontaneous generation 4. Bacteria is an example of prokaryoric cwll 5. Prokaryote is a type of cell that has no nucleus and no cell membrane but has cytoplasm
WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.
Ernst Mayr defined a biological species as a population whosemembers can exchange genetic material during reproduction (seechapter 14). How does horizontal gene transfer complicate thisdefinition of species?
Place the following organisms in the order in which they are thought to have appeared on the Earth (from earliest to most recent). - 1. 2. 3. 4. organisms tolerant of oxygen photosynthetic organisms eukaryotic cells heterotrophic organisms 2) n their laboratory experiments of simulations of early Earth, Miller and Urey observed the abiotic synthesis of abundant amounts of DNA amino acids liposomes genetic systems
All living things are divided into three domains: bacteria, archaea, and eukarya. They have several traits that are specific to each domain or shared across the domains. Based on this information, what traits would the last universal common ancestor (LUCA) be expected to have? A. Nuclear envelope, introns in genes, and peptidoglycan in cell walls. B. Histones associated with DNA, circular chromosome, and peptidoglycan in cell walls. C. Unbranched hydrocarbons in membrane lipids, histones associated with DNA, and introns in genes. D. Circular chromosome, unbranched hydrocarbons in membrane lipids, and one kind of RNA polymerase.
Approximately how long ago did homo sapen (humans) first appear on Earth 2,000 years ago 5-7 million years ago 65 million years ago 150,000 - 200,000 years ago Hominins developed their unique larger brains before acquiring the ability to move on two feet. True False the production of atmospheric oxygen in Earth's environment started with photosynthesis by prokaryotes photosynthesis by multicellular eukaryotes photosynthesis by single celled algae photosynthesis by land plants Homologous structures among animal provide evidence for evolution in that theses structure are all produced by the same gene different in different animals, but are modifications of the same basic structure similar in function, but of different basic structure all different structures within the same species
Within six months of effectively using methicillin to treatS. aureus infections in a community, all new S. aureus infectionswere caused by MRSA. How can this best be explained?(A) A patient must have become infected with MRSA fromanother community.(B) In response to the drug, S. aureus began making drugresistant versions of the protein targeted by the drug.(C) Some drug-resistant bacteria were present at the startof treatment, and natural selection increased theirfrequency.(D) S. aureus evolved to resist vaccines
Here is the question: What was the likely source of the raw material incorporated into the first life forms? I believe it is carbon, but I don't know why it is carbon. What I mean is, why is carbon considered the thing that makes something alive? Why are eukaryotes and prokaryotes simply considered alive just because they have carbon. Would that mean that carbon is alive because carbon has carbon? I would appreciate an anwser because I'm really trying to understand everything I run across. I love educating myself and I'm on a quest for knowledge. Thanks guys!
Fossil evidence indicates that prokaryotes have been around for about 3.5 billion years, whereas the origin of eukaryotes has been dated at only about 1.5 billion years ago. Suggest why, in spite of the lesser time for evolution, eukaryotes are much more diverse (have a much larger number of species) than prokaryotes.
Which of the following statements are TRUE about organisms in the Domain Bacteria? I. Consist of bacteria and cyanobacteria II. Some are photoautotrophs III. Genetic material is a single stranded DNA IV. Organelles are not present
