Answer:

Natural selection.

Explanation:

Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)

A student wanted to know which sugar would yield the greatest amount of energy for the cell when metabolized by mitochondria. Th
Naddika [18.5K]

Answer:

A possible hypothesis would be:

IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria

Explanation:

The hypothesis is a testable explanation aimed at providing a theoretical explanation to a question. The hypothesis is a predictive statement about the possible solution, which can be tested. A hypothesis must be testable via experimentation. It often has an IF, THEN format.

Hence, in the case experiment where a student wanted to know which sugar (maltose, glucose or sucrose) would yield the greatest amount of energy for the cell when metabolized by mitochondria. A possible hypothesis of this experiment will be that: IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria

Note that, this hypothesis must be testable by conducting an experiment and it doesn't have to be true. It can be disproved or proved by the outcome of the experiment. In this case, the hypothesis is giving an educated guess that maltose is the sugar that will yield the greatest amount of energy for yeast cells

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by a(n) _________ system. Multiple Choice riboswitch
zmey [24]

Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.

  • Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
  • A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
  • Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

How is the scientific method used in earth science (it was due yesterday)
Bingel [31]

Answer: <em>The steps used in scientific methods are to ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate results. A controlled experiment tests only one factor at a time so that scientists can determine the effects of changes to just that one factor.</em>
