Help! ASAP, this is due tomorrow and I’m struggling as this isn’t what they taught us. The question is: Explain why the bacteria

shown (E. coli) have a second membrane outside the
peptidoglycan.

The second membrane protects e.coli (Gram-negative bacteria) against a harsh environment.

The outer membrane indirectly helps stabilize the inner membrane as peptidoglycan layer in Gram-negative bacteria is relatively thin than gram positive bacteria ( they have multilayer pepdtidoglycan )

Answer:

The outer membrane of Escherichia coli consists of lipopolysaccharide, phospholipid, protein and Enterobacterial common antigen. The outer membrane as a layer has a protective function. Several specific functions can be attributed to individual constituents. hope this helps!

if a prey evolves to increase its defenses, its predator often evolves to counteract this change. a. True b. False​
DerKrebs [107]

Answer:

a. True

Explanation:  

Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.

Which is not a major difference in the organization or content of prokaryotic and eukaryotic genomes?
bulgar [2K]

Answer:

All of the above are true

Explanation:

Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:

- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.

- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.

- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.

- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.

Based on this, all of the above options are TRUE
