<span>The
activity which is the best demonstration of Joseph John Thomson's use of creativity in
his work when he devised a better method and equipment in studying cathode rays.
This activity led to the discovery of originally termed particles “corpuscles”
which are now known as “elections”. This discovery also upended the dominating
theory that atoms are the smallest fundamental unit.

Answer:
The correct answer is option A. demonstrates that the E. coli cultures were viable.
Explanation:
In this lab experiment or culture, Plate I and plate III demonstrate, that E.coli bacteria can grow both in the presence and absence of plasmid DNA if ampicillin is not there.
So, which means that plasmid DNA is not required for the growth of E.coli in absence of ampicillin. The presence of growth in wild type (plate 1) and a plasmid containing bacteria (plate 3) in media without ampicillin shows that bacteria are viable in nature.
The Diplomonads and Parabasalids are the two groups that are adapted to anaerobic conditions and contain modified mitochondria that lack DNA.
<u>Explanation:</u>
The existence of a mitochrondrial-remnant organelle and nonfunctional, named a mitosome distinguishes diplomonads. Parabasalids are distinguished by a semi-functional mitochondria termed as hydrogenosome; they are made up of parasitic protists, including Trichomonas vaginalis.
Diplomonads function in anaerobic circumstances, and use alternate pathways to generate energy, like glycolysis. Growing cell of the diplomonad has two identical nuclei and utilizes multiple locomotive flagella. Trichomonas vaginalis, a parabasalid that induces a human sexually transmitted infection, uses these pathways to pass via the urogenital tracts of males and females.
Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.
Answer:
The tomato is the edible berry of the plant Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America and Central America. The Nahuatl (the language used by the Aztecs) word tomatl gave rise to the Spanish word tomate, from which the English word
