Answer:
True
True
Explanation:
Lactose transporter are not absent from the membrane before induction. They are already present in the cell membrane. Lactose requires some transport medium, for this reason protein acts as transport medium for the lactose.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.

The question is not given. You just placed some statements. Apparently, here you have some definitions to pair with the type of elements. So, I will separate the statements as per my best understanding. If the question requires anything else tell me to give you more details.
<span>1. Metalloid
Metalloid is an element that has properties in between metals and non metals, this is metalloids have some properties of both.
Then you can pair it with ---> moderate ability to conduct heat and electricity
2. noble gas
The elements that are knwon by not reacting with other elements are noble gases.
Then, pair this with ---> will not react with other elements.
3. metal:
Metals are malleable, polishes to a luster and are good conductors of heat and electricity.
Then pair metal with ---> malleable, polishes to a luster;
conducts heat and electricity well
4) non metal gaseous: non metal are poor conductors
So, pair this with ---> does not conduct heat or electricity well
Given that the question is no
