Answer:
an inducer
Explanation:
An Enzyme is a protein molecule found in cells which work as biological catalysts.
They speed up chemical reactions in the body, but do not get used up in the process, and can be used over and over again.
In chemistry inducers are molecules that regulates gene expression, and can bind to protein repressors or activators.
Lactose here acts as an inducer because it inactivates the repressor of an operon.
Because oxygen is more electronegative than hydrogen, the water molecule is polar.
Explanation:
Flourine has atomic number of 9 and hence 9 electrons in its neutral state. The full electronic configuration is given as;
1s2 2s2 2p5
Carbon has atomic number of 6 and hence 6 electrons in it's neutral state. The noble gas notation as the following format;
[closest noble gas before the element] remaining electrons
The nearest noble gas to carbon is Helium, the noble gas notation is given as;
[He] 2s4
Answer:
a new substance is formed, if heat is formed, color change, the evolution of gas, and bubbles or fizzing
