when Clover seeds are coated with bacteria What does this bacteria do for the clover and...
1. How do bacteria do C.R. without mitochondrion? - 2. What does the pacing graph show? 3. Where do you get the "extra" speed? 4. Why does the muscle lab data drop off? 5. Do plants do C.R. also? So, do they have mitochondria? 6. What does the glucose turn into? del til at holde sig 7. How do mitochondria reproduce? 8. During glycolysis, one glucose is broken down into _(3C). 9. Acetyl CoA is a C molecule. 10. Where...
What do botanists call plants that form flowers and seeds through the sexual process that allows more mixing of genes and evolution to proceed more quickly? 1. Sexualphores 2. Spermatophores 3. Angiosperms 4. Gymnosperms
Your body encounters a bacterium that is coated in LPS. How does the innate immune system recognize and respond to the bacteria in your system? Make sure to include any pathways of activation, cells or processes that will be utilized.
1) What does beta lactamase do, and how is that helpful in selecting bacteria that contain your plasmid of interest (in this case, pUC19)? 2) (6 points) What protein fragment does the gene lacZ alpha encode for? a. When this peptide is expressed in E. coli DHSq, it combines with an E.coli expressed peptide to make a functional protein. What is this E. coli encoded peptide called? b. What is the biological role of the complete protein that is made...
Question 18 4 pts What role do restriction enzymes play in bacteria? How do bacteria protect their own DNA from the action of restriction enzymes? Change the surface proteins of bacteria; since DNA is not protein, there is no need for protection Cut foreign DNA into pieces; bacteria have RNA genomes. Destroy invading viral DNA: bacterial DNA does not contain the restriction enzyme recognition sequences. Restrict the growth rate of bacteria; bacterial DNA is restriction enzyme resistant. Question 18 4...
Bacteria and plants that live in soils will sometimes produce biogenic siderophores which are small organic compounds that act as ligands to complex metals. It can be difficult for bacteria and plants to move around and find nutrients on their own sometimes, so they rely on siderophores to do the job for them. They produce the siderophores, release them when water passes by, and the siderophores complex metal nutrients like iron, and the bacteria or plants can then suck up the iron-siderophore...
If two heterozygous plants with round seeds are mated, what fraction of the progeny with round seeds are genotypically heterozygous? a) 2/3 b) 1/4 c) 1/2 d) 3/4
(More Genetics Problems and Difficult Genetics Problems). MORE GENETICS PROBLEMS 1. When tall plants mate with dwarf plants, only tall plants occur in the offspring. Assign symbols and show the phenotypes and genotypes in the parental (P) and first filial generations for a cross between tall plants and dwarf plants that produces only tall plants. 2. Show the expected outcome when the F1 plants in problem #1 are crossed. Be sure to give both phenotype and genotype ratios for these...
As bacteria have always been referred to as growing in colonies, how does the concept of biofilms apply to bacterial growth?
Like any seeds, watermelon seeds lose their viability over time. If they've been left sitting for years, it's possible that only a small proportion of the seeds may sprout when planted. If they have been stored in a cool, dark, dry location, they have a better chance of sprouting. Drake has a large quantity of old watermelon seeds he's been saving, and now wants to know how many of them may still be able to sprout. He randomly selects 100...
