The material that makes up the membrane cell is the phospholipids, cholesterol, proteins, and carbohydrates.
Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.
1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.
2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.
3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.
4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.
Answer: it’s A
Explanation:
Because uni means one and that means unicellular is only made of one cell
Answer: The correct answer is -
C) Mutualism.
Explanation:
Mutualism is a type long term biological relationship between two organisms belonging to same or different species in which both are benefitted from one another.
For example - E.coli bacteria, present large intestines of human, gets food and place to live in our digestive tract. In return, the bacteria produce vitamin K, which make it harder for other disease causing bacteria to establish in our system.
Thus, option C) is the right answer.
