Flowering plants have common ancestors with other plants and plant-like organisms. The table below shows the last common ancestor shared between flowering plants and two other types of organisms. Last common ancestor with flowering plants Cone-producing plants 250 million years ago Green Algae 500 million years ago A scientist compares the amino acid sequences of a protein produced by flowering plants, a cone-producing plant, and green algae. What prediction about these sequences is supported by the data in the table?

Flowering plants have common ancestors with other plants and plant-like organisms. The table below shows the last common ancestor shared between flowering plants and two other types of organisms. Last common ancestor with flowering plants Cone-producing plants 250 million years ago Green Algae 500 million years ago A scientist compares the amino acid sequences of a protein produced by flowering plants, a cone-producing plant, and green algae. What prediction about these sequences is supported by the data in the table? The amino acid sequences for flowering plants and cone-producing plants will be the most similar. O The amino acid sequences for all three organisms will be identical. O The amino acid sequences for flowering plants and green algae will be the most similar. O The amino acid sequences for all three organisms will have no similarities.
If you are to compare the genetic sequences between monkeys and fungi, what molecular sequence are you going to use? Why? How about comparing genetic sequences of monkeys to humans, what genetic sequence will you use? Provide an explanation.
A group of researchers are trying to determine the relationship between various groups of organisms. The researchers analyze the amino acid sequence of the protein cytochrome c in various groups of organisms. Once they sequence cytochrome c in all organisms, they determine the number of amino acid substitutions in each group. The results can be seen in the graph below, which plots the data with respect to the time since the divergence of the members of paired groups from a common ancestor. A B mammals and reptiles с Number of Amino Acid Substitutions (per 100 amino acids) in Cytochrome, c D 60- 50+ 40+ 30- 20+ 10+ 0 0 O birds and reptiles A graph showing when various groups of organisms diverged from a common ancestor Based on the graph above, can you conclude which of the following organisms are most distantly related? 200 400 600 800 1,000 Time Since Divergence from a Common Ancestor (millions of years) fish and land vertebrates mammals and reptiles birds and mammals insects and…
Transfer RNA (after becoming “charged” with an amino acid) contains which of the following covalent bonds that are absent in all other forms of RNA? the glycosidic bond the phosphodiester bond the hydrogen bond the aminoacyl bond the peptide bond The green sea slug carries the genes for synthesizing chlorophyll (apparently acquired from the chloroplasts of green algae), illustrating which type of genetic change leading to evolution? horizontal gene transfer gene deletion gene duplication mutation exon shuffling
A consortium of dairy and beef farmers has hired you to study the evolutionary origins of domestic cattle. They particularly want to know whether the humped zebu cattle of Asia and the cattle of Africa are derived from different species of wild cattle than European breeds. Outline a complete research program to study this question. Describe the sequence of steps you would need to do, what kind of data you would collect, and the methods you could use to evaluate possible trees and branches.
Geneticists have determined the amount of DNA, the number of different genes, and the size of the cell/nucleus in a wide variety of model organisms. as we move up the phylogenetic scale, the amount of DNA/cell increases much more rapidly than does the volume in which that DNA must be packaged. How do higher organisms package their DNA in the interphase cell?
The Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes. In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.
The table below shows short DNA sequences from a gene in a closely related group of dragons, as well as their close relative, the Winged Ground Lizard. Assume each change in the DNA sequence evolved only once. Draw a phylogenetic tree that represents the relationship among the dragon species, as well as the Winged Ground Lizard. Indicate the locations on the tree where there is a change in the DNA sequence and indicate the site position and what the change is
Asian tiger mosquito Trace its origin and evolutionary history or changes in the species. Describe its structures and their functions. What is the importance of this species to our environment? Give trivia about this species. Does this organism produce oxygen? Explain. What are the ancestral species of your chosen organism? Has this species been genetically engineered? If yes, in what way? How does this species reproduce? What organisms have similar structures to this species? Do these structures have the same function? Does the species have tissues, organs, and/or organ systems? What is its role in the flow of energy? Give at 15 least a sentence to each question.
What are trumpet cells in brown algae? What type of cells do they resemble in true plants? Is their presence in brown algae a sign that brown algae are related to the ancestors of true plants, or is it just a remarkable case of convergent evolution?
Evolutionary theory predicts that species are related, not independent. Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? O A. Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. O B. All prokaryotes and eukaryotes use DNA to carry their genetic information. OC. Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. O D. Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other. O E. The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. «< Question 5 of 120 A Moving to another question will save this response. 11:51 AM 12/16/202 End F10 pgUP F11 PgDn F12 Home PrtScn F8 DII F5 F7 F6 F3 F4 F2 & #3 2$ 7 8 9.…
A researcher studying two species (species 1 and species 2) sequences a short stretch of eight codons from the same gene, gene B, in each and compares them. Species 1 and species 2 had a most recent common ancestor 50 million years ago. Species 1: ATC GGG CGG GAC TTA CTA TAT GCC Species 2: ATT GGG CGG GAC TTG CTA TAT GCC Given the differences between the sequences of the two species' genes shown here, what evolutionary force can you predict is most likely in operation on gene B?
