The first serious attack on the idea of spontaneous generation<span> was made in 1668 by Francesco Redi, an Italian physician and poet. At that time, it was widely held that maggots arose </span>spontaneously<span> in rotting meat. Redi believed that maggots developed from eggs laid by flies.</span>
<span>The correct answer is A. atoms. Atoms are studied by physics and chemistry, not by ecology. Ecology studies organisms, populations, and the earth in terms of climate, pollution prevention, natural habitats and biomes, and all kinds of similar things that are related to living on earth. Atoms are irrelevant for the study of ecology.</span>
to be honest I just wanted to say nice profile pic okay I'll leave u alone now
The question is incomplete as it does not have the options which are:
A. bioremediation
B. mutualism
C. quorum sensing
D. quorum settling
E. mass-settling
Answer:
C. quorum sensing
Explanation:
Quorum sensing is the gene regulation mechanism used by the bacteria to communicate with the other bacteria. The quorum sensing process depends on the number of bacterial cells or the density of the cells.
When the bacterial number increase in number then the bacterial cells send the signal to the nearby cells and and regulates the expression of the gene. In the given question, the same chemical signal process depends on the density of the cell and thus quorum sensing is correct.
Answer:
K+-coupled.
Explanation:
The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.
The passive transport do not require the energy for its transport whereas the active transport require energy. The K+ coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.
Thus, the correct answer is option (C).
