Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

Describe the effects of the various antibiotic drugs you used. Were they all equally effective at controlling bacterial growth?
Kipish [7]

Answer:

Basically, most   antibiotic drugs  are not  effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of  diameter of the  bacterial growth . <u>This is because the diameter   is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a  measure  of how effective  it  can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control  the bacteria, While  a large diameter is an indication of low effectiveness of the drug.

Based on this analogy, penicillin with wide usage for control  of bacteria growth  with  diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm  or 6mm depending on   type of bacterial.

Therefore, the least 3mm  diameter presented by penicillin is an indication that , antibiotic drugs  are not effective enough, and further research need to be done to control growth of bacteria and therefore its   pathogenic  effects.
