Question

1 multiple answer 1 point which of the following biomolecules play an important role in the cell membr nucleic acids proteins carbohydrates lipids 2 multiple answer 1 point which of the following are the two types of cellular division? transcription meisosis mitosis replication 3 multiple choice 1 point which of the following cell membrane components prevent the cell membrane polar heads non - polar tails phospholipids cholesterol clear my selection

Explanation:

1. Proteins are involved in transport and cell - cell recognition in the cell membrane. Carbohydrates are important for cell - cell recognition and adhesion. Lipids (phospholipids) form the basic structure of the cell membrane. Nucleic acids are mainly for storing and transmitting genetic information and are not major components of the cell membrane structure.
2. Mitosis is the type of cell division for growth, repair, and asexual reproduction in somatic cells. Meiosis is for the production of gametes in sexual reproduction. Transcription is the process of making RNA from DNA and replication is the process of duplicating DNA.
3. Cholesterol helps maintain the fluidity and stability of the cell membrane, preventing it from being too rigid or too fluid.

Answer:

1. B. Proteins, C. Carbohydrates, D. Lipids
2. B. Meiosis, C. Mitosis
3. D. Cholesterol
