Q3. Is it true that all known eukaryotes have mitochondria? A. Yes, but some eukaryotes have mitochondria that do not contain DNA. B. Yes, but some have only one mitochondrion per cell. C. No, but all eukaryotes contain mitochondria-derived genes. D. No, but those that don't contain mitochondria contain chloroplasts instead.
1. Why was the great oxygenation event important for mitochondrial development? a) In your own words, define symbiotic. 2. Chloroplasts and mitochondria both contain a circular DNA chromosome, and ribosomes. Why does this evidence support the theory of endosymbiosis as the mechanism for the origin of eukaryotic cells? a) Today, could mitochondria live independently of their eukaryotic cell host? Give two pieces of evidence to support your answer.
Question 3. The hypothesis thatexplains the origin of eukaryotic cellsas the result of two or more simplercells developing a relationship withone another is called:A. Theory of panspermia.B. Theory of symbiosis.C. Evolutionary theory.D. Theory of endosymbiosisE. Law of eukaryotic evolution.
Regarding the following statement: “Human females are a mosaic of cell types” (2-3 sentences maximum per answer) A) What is the basis for this cellular mosaicism? B) Why has this female-specific mosaicism evolved? ? C) What is the molecular (molecular = proteins, nucleic acids, other small molecules) basis of this mosaicism ?
Hello, I need help answering 5c & 5d using the phylogeny below(letter (A) graph to the left). Pls and thank you! a) In the 1990s, when only mitochondrial DNA sequencing was available, geneticists claimed that there was no hybridization between humans (Homo sapiens) and Neanderthals (Homo neanderthalensis). Does the phylogeny shown above support the claim humans did not hybridize with Neanderthals in the past? How can you tell? b) Once nuclear DNA sequencing became fast and able to handle sequencing ancient DNA, living humans were found to have some Neanderthal genes. Is this finding clear evidence that some early modern humans did indeed hybridize with Neanderthals? Why? c) Did female H. sapiens hybridize with Neanderthal males to produce fertile offspring that then back-crossed with modern humans? What does the graph say about this? d) Did male H. sapiens hybridize with Neanderthal females that then back-crossed with modern humans? What does the graph say about this?…
You isolate a cell from a eukaryotic species where n = 14. The cell contains 28 DNA molecules. choose best answer from the bolded words in each phrase: 1. The cell could/could not be at the end of stage G1 of the cell cycle, as the cell in this stage is diploid/haploid and each chromosome is made of 2/1 DNA molecule(s). 2. The cell could/could not be at the end of stage Metaphase I, as the cell in this stage is diploid/haploid and each chromosome is made of 2/1 DNA molecule(s). 3. The cell could/could not be at the end of stage Prophase II, as the cell in this stage is diploid/haploid and each chromosome is made of 2/1 DNA molecule(s).
One piece of supporting evidence for the endosymbiotic theory for the origin of eukaryotic cells is thata. eukaryotic cells have internal membranes.b. mitochondria and chloroplasts have their own DNA.c. Golgi bodies and endoplasmic reticulum were present in ancestral cells.d. the nuclear membrane could only have come from another cell.
The extra energy required for the evolution of the highly complex eukaryotic cell was possible because: a) mesosomes released enzymes into the nucleus b) two types of prokaryotic bacteria became endo symbiotic invaders of the complex cells c) the DNA of the eukaryote cell functions within the nucleoid area d) chloroplasts were able to use O2 to conduct photosynthesis e) the space between the two layers of the nuclear membrane contained mitochondria
