Biology

crimeas [40]2 years ago

Answer:

C)

Explanation:

Bacteria are prokaryotic, which means they (generally) don't have organelles or a nuclear envelope around their nucleus.  They have ester linkages in the phospholipids in their cell membranes, while archea, which are also prokaryotic, have ether linkages.  Ether linkages are more chemically stable than ester linkages, and since archea live in extreme environments this is helpful.  

Bacteria are not multicellular and do not have organelles (complex cellular structures) besides ribosomes.

oksian1 [2.3K]

The process of cellular respiration is achieved in plants by the process of photosynthesis. The energy from glucose is derived in this process. The steps of the cellular respiration includes the glycolysis, the kreb's cycle, and the oxidative phosphorylation. During this process, the proton concentration builds in the thylakoid space of the plant cell.

Inessa [10]

Answer:

A) Effect of findings on other family members would be most important factor.

Explanation:

Genetic research is done on human DNA to know the genes and environmental factors associated with certain disease.

Institutional review board (IRB) is the regulatory authority to protect the rights of subjects invloved in a resaerch.

The genetic reaerches usually involve families, so the researcher subjects and the result of research is related to all subjects that cause increased information flow between subjects and effect their decision to partcipate independently in research. Also, if the research involve therapeutic studies special precautions would be taken to choose the subject
