Answer:
contains DNA associated with protein, contains naked DNA
Explanation:
E coli are prokaryotes with naked DNA found in the cytoplasm. In contrast, human liver cells contain DNA present in a nucleus, a membrane-enclosed organelle. The DNA is associated with proteins (forming a structure called chromatin).
Human liver cells contain mitochondria, but E Coli do not contain membrane-bound organelles.
Eukaryotic ribosomes are larger than prokaryotic ribosomes. Eukaryotic ribosomes are 80S in size, prokaryotic are 70S in size.
The contractions of the heart is what creates out blood to pulse through out body and is the basis of our blood pressure; which means this statement is TRUE.
The systolic number (top) of the blood pressure is our heart physically pushing the blood out of the heart and to the rest of the body.
The diastolic number (bottom) of the blood pressure our heart at rest when it has just finished with one pump.
Answer:
ATP donates energy through C phospho anhydride bond hydrolysis.
Explanation:
ATP or adenosine triphosphate is an energy rich compound which contain 3 phosphate moiety that are linked by 2 high energy phospho anhydride bonds.
The hydrolysis of phosphoanhydride bonds releases high amount of free energy which is used by cellular system of our body to exhibit various cellular,biological and physiological functions.
Some anoxygenic photosynthetic bacteria are able to use H2S or hydrogen sulfide as an electron donor.
Opportunistic pathogens only cause infection under certain circumstances eg in immune compromised hosts.
Answer:
The correct answer is option C) "are processed by proteases into both opiate and non-opioid peptides".
Explanation:
The opioid propeptides, as well as any other propeptides, is a protein precursor that needs to be excised into a smaller form to acquire its active form. The opioid propeptides are processed by proteases into both opiate and non-opioid peptides, where the latter could be active or non active. Opiate peptides are enkephalins, endorphins, and dynorphins that act by blocking secondary systems, such as the ones that cause pain perception.
