Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.
Hence , the correct option is B.

Please Help! What molecules need to travel through ATP synthase to help it create ATP?
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

On May 18, 1980, Mount St. Helens in Washington State experienced a huge volcanic eruption after a magnitude 5.1 earthquake. During the eruption, hot ash and pumice poured down the west, south, and east sides of the mountain, melting the snow and ice at the top of the volcano and producing volcanic mudflows. Which type of process first occurred in the ecosystem around Mount St. Helens after it erupted?
Answer:
primary succession
Explanation:
Primary succession starts in regions where there is no soil or where the soil is incapable of sustaining life due to any recent lava flows or newly formed sand dunes. Primary succession may lead to the formation of islands on land formed from glacial retreats or on new volcanic rock.
Primary succession occurred in the ecosystem around Mount St. Helens after the volcano erupted.

How does a radio use radiant energy
Answer Explanation:
A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.
When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.

what three animals are closley related to a tiger
Answer:
The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard, and jaguar.
Explanation:
Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. The geographic origin of the Panthera is most likely northern Central Asia or the Holarctic region. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.
Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu province of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.

Carbohydrates have chemical bonds that are a good source of energy for living things. A monosaccharide is a carbohydrate made by plants when energy from the sun combines water and carbon dioxide.
How are the two other types of carbohydrates formed? Give examples of each type.
Explanation:
The other two types of carbohydrates, disaccharides and polysaccharides, are formed when monosaccharides link together to form larger molecules and chains. A disaccharide is a sugar that is made from two monosaccharides (di=two). For example, sucrose is a disaccharide that is made from the bonding of glucose with fructose, which are both monosaccharides. Sucrose is known as table sugar, and is found naturally in plants. Polysaccharides are large, complex molecules that are formed when monosaccharides or disaccharides link together in repeating units to form long chains. The most abundant polysaccharide in the world is cellulose, the substance that makes up the cell wall of plant cells. Starches are also examples of polysaccharides, and these are stored in plants such as grains, corn and wheat.
All living organisms must obtain energy in order to survive, and most organisms rely on carbohydrates as energy sources. These molecules are made through the process of photosynthesis, and they store the sun's energy within them.

Cholesterol is synthesized by all animal cells and is an essential structural component of animal cell membranes. Cholesterol is the most common steroid and is mainly synthesized in the liver. Cholesterol also serves as a precursor for several important biological compounds including all, EXCEPT: A) insulin B) vitamin D C) bile salts D) testosterone
the answer is insulin. because the precursor for insulin is called pro insulin
Cholesterol does not serve as the precursor for insulin. So the correct option is A.
What is cholesterol?Cholesterol is a wax-like substance. Cholesterol is considered to be bad among the general public but it is not inherently “bad.” Our body needs for building cells and making vitamins and several other hormones. Cholesterol levels, in excess, can pose a problem.
Cholesterol can come from two sources. These are synthesized by the liver and from foods from animals. The liver produces all the required cholesterol but the remainder is obtained from foods. For example, meat, poultry, and dairy products of them contain dietary cholesterol.
These are the same foods that are also high in saturated fats and trans fats. These fats cause the liver to make more cholesterol than required or more than it normally does. This added production of cholesterol, for some people, means they go from a normal level of cholesterol level to unhealthy level of cholesterol.
Therefore the correct option is A.
