Answer:C). A phospholipid bilayer with proteins
Explanation: A cell membrane is a phospholipid bilayer with proteins embedded in it. The fatty acyl chains of the phospholipids are non polar and hydrophobic while the phosphate groups are polar and hydrophilic. The hydrophobic regions of the phospholipids interact with each by facing each other, forming a bilayer with a fluid interior. The polar head groups face outward interacting with the external environment of the cell. Proteins are embedded in this bilayer and they float in this sea of phospholipids. Proteins anchored to the membrane through interactions between the hydrophobic regions of the phospholipids and the amino acid side chains of the proteins. These lipids and proteins swim laterally in each face of the bilayer but movement from one face of the bilayer to another is restricted.
Answer:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.

False
<h2>Explanation:</h2>
According to Sigmund Freud human consciousness have been divided into three levels of awareness: the conscious, precociousness, and unconscious. These stages are never understood by any person at the same time. There is always a transition period between these segments. For example the transition stage from wake to sleep where we see a gradual reduction in consciousness with fuzzy, halfway states in between conscious and unconscious.
Answer:
Explanation:
Proteins are involved in almost every function of cell and inside the body and each protein is specific for its role. Some of them are
1) Protein constitute major part of structure of cell. Proteins are major constituent of cell membrane along with lipids.
2) Enzymes which are proteins in nature catalyze all the important chemical reactions inside and outside the cell e.g transporting material across the cell, synthesizing and repair of DNA
3) Hormones which are proteins play important role in the regulation of metabolic reactions inside the cell
4) Regulation of cell division is performed by DNA-associated proteins
5) Proteins plays important role in storage of iron inside the cells
6) Proteins can be stored as fats inside the body and used as energy when needed by cells for its metabolic activities.
