On the off chance that the cell membrane can't carry out its activity appropriately, this can make the cell quit working legitimately. On the off chance that numerous cells have awful cell membrane , the illness can influence a whole organ or even the entire body. In a significant number of these cell membrane sicknesses, proteins inside the cell layer don't transport materials appropriately. It isn't really that the layer itself vanishes, rather that specific parts don't work. Water, salt, and different supplements can wind up plainly imbalanced, prompting side effects often detrimental.
Backpedaling to the house similarity, on the off chance that you evacuated the ways to your home, creatures could move in and cause harm. In the event that every one of the houses in an area lost their entryways also, the area would have significant irritation administration concerns.
Answer: rough endoplasmic reticulum--b
Smooth endoplasmic reticulum--a,c,d
Explanation:The rough endoplasmic reticulum has numerous ribosomes attached to it. Thus it has a coarse texture.it is involved in the production of proteins. The ribosomes receives the messages to produce a protein from the messenger RNA, the ribosome the packs amino acid into proteins and transfers it to the rough endoplasmic reticulum.
The smooth endoplasmic reticulum does not have ribosomes attached.it is involved in the production of non-protein molecules eg lipids and fats.
It is an also important organelle for the metabolism of the cell.it helps in detoxification in the liver. It also stores calcium for use in the skeleton.The sarcoplasmic reticulum is an modified smooth endoplasmic reticulum
Answer:
Proteins and lipids exist as separate but loosely attached molecules that can move around
Explanation:
Cell membranes are mainly composed of lipids, proteins, and also carbohydrates. Phospholipids are the most abundant type of lipid and the main constituent of the cell membranes. Membrane proteins are divided into two types according to their interactions with the cell membrane: 1-integral (intrinsic) and peripheral (extrinsic) proteins. These peripheral proteins are loosely attached by ionic bonds or calcium bridges with the phosphate heads of the phospholipids; whereas integral membrane proteins contain side chains that interact with fatty acyl groups of the phospholipids. Cell membrane fluidity indicates how easily lipids (e.g., phospholipids and cholesterol) and proteins (e.g., intrinsic proteins) diffuse laterally in the cell membrane. This fluidity is affected by the amount of cholesterol, temperature, and the ratio of unsaturated to saturated fatty acids. Saturated fatty acids have no double bonds in the hydrocarbon chain, whereas unsaturated fatty acids have at least one double bond (these double bonds increase fluidity). Moreover, higher temperatures increase membrane fluidity, whereas cholesterol molecules function to regulate membrane fluidity: at high temperatures cholesterol molecules stabilize the membrane, whereas at low temperatures intercalate between phospholipids, thereby preventing them from clustering together.
Secondary or second-level consumers eat primary consumers. Tertiary or third-level consumers eat lower-level consumers and are sometimes called final consumers. Some secondary and tertiary consumers eat plants as well as lower level consumers, making them omnivores.
