Staphylothermus marinus is an extremophile archaea that inhabits deep ocean hydrothermal vents at temperatures near boiling. what would be the effect on this species' environmental requirements if the membrane lipid linkages were changed from ether bonds to ester bonds?
a. it would require shallower depths with more light.
b. it would only be able to survive farther away from the vents where there is less methane.
c. it would only survive in freshwater habitats.
d. it would only survive in areas farther away from the vents at lower temperatures.
e. it would require anaerobic conditions such as those found in hot springs.

Which prevent errors in dna replication? a. helicase enzyme checks the dna for errors. b. each base can attach to only one other type of base. c. ribosome enzymes prevent errors from happening. d. dna contains no complementary base pairs.

1. the passing of is the basis of heredity. 2. our encode the instructions that define our traits. 3. each of us has thousands of genes, which are made of and reside in our chromosomes. 4. in addition to our genes, the we live in also define our traits. 5. humans have two complete sets of chromosomes. 6. when parents conceive a child, each parent contributes set of chromosomes. 7. every child receives of its chromosomes from the mother and half from the father. 8. this transfer takes place at when the father’s sperm joins the mother’s egg. 9. while most cells in our bodies have two sets of chromosomes, or a total of egg and sperm each have chromosomes. 10. when egg and sperm unite they create a single cell called a 11. each parent contributes complete set of chromosomes to their child. 12. since the parents contribute the chromosomes to each new child, every child inherits a unique set of chromosomes. 13. as a result, every baby will have a combination of traits.

Before the can be observed by using a transmission electron microscope, cells are sliced into very thin sections. what disadvantage does this procedure present in the study of cellular parts
