Digestion is the process by which food and drink are broken down into their smallest parts so that the body can use them to build and nourish cells and to provide energy.
A hypothesis is something u assume before the research has been made and a theory is a explanation already supported by evidence/data.
Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Answer:
D. a protein is formed.
Explanation:
The formation of a dipeptide is the join of two amino acids by a peptide bond, when this occurs a molecule of water is produced, two amino acids are joined together and a double bond forms between the carbon and the nitrogen from the two amino acids . A protein is composed by one or more large chains of amino acids, in other words, a great number of peptide bonds are needed to form a protein not just one which will give a dipeptide or two which will give a tripeptide.
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.
