Answer:
Simple Diffusion across the Cell (Plasma) Membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Explanation:
While monosaccharides typically all have a molecular formula that is a multiple of CH20, they differ in factors such as the length of the carbon skeleton or the orientation of their atoms around asymmetric carbon atoms. What is the impact of this variation in molecular structure? 1.) Different monosaccharides will form disaccharides with the same properties. 2.) Cells will use more energy to metabolize a wider variety of polysaccharides. 3.) Molecules that all share the same bonding pattern but have different properties will be produced. 4.) Sugars with different properties that can build a wide variety of carbohydrates will result.
Answer:
Sugars with different properties that can build a wide variety of carbohydrates will result.
Explanation:
This is the correct answer.This is because the arrangement of the monosaccharides units though the linking of the monomers with the glycosidic bonds via condensation reaction goes a long way to determine the orientation of the monosccharides and therefore the chemical properties displays.
Therefore when monosaccharides are linked by glycosidic bonds in different ways to form diasaccharidesa and polysacharrides,these macromolecueles display different chemical properties and physical properties from one another.
This is evident in cellulose((beta-glucose) whose 3-helix structure strengthened the wall of green plants.This orientation ensures that the hydrogen of -OH group is attached to the Oxygen of the same OH in the same molecule,or to that of another molecule.This formed hydrogen bond strong enough to form microfibrils which are held by fibres.
This is different from the structure of glycogen(from alpha 1,4 and 1,6-glycosidic bonds) despite the two been formed from monoscacharides. This is also evident in the structure of starch formed by alpha glucose
It is the orientation of the monomoers of the monosccharides in space that determines this different properties
what objects can minimize the effect of friction?
Answer:
There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
Breathing occurs when the changes in air pressure causes air to flow into or out of your lungs as you inhale or exhale.

how does pinocytosis work
Answer:
In cellular biology, pinocytosis is a type of endocytosis that involves the taking in of extracellular fluid into the cell. By utilizing this process, the cell can draw fluids and even solutes (as long as they are dissolved in fluids) into the cell with only a small amount of energy (ATP) needed.

Fresh milk has several parts that a farmer can separate and sell. A farmer removes the top layer of fat from fresh milk. What property does the farmer use to separate the fat from the rest of the milk?
A. density
B.Magnetism
C. Boiling Point
D. Electrical Conductivity
The fats present in the top layer of fresh milk can be separated from the rest of the milk by the help of density gradient. Thus, the correct option is A.
What is density gradient?Different molecules present in a cell or liquid can be separated on the basis of density gradient. Density gradient is the difference in the density of compounds. It is a spatial variation in density over an area in a compound or cell. It is used to describe the changes in the densities of matter. This is used widely in laboratory for the purpose of the separation of compounds such as DNA, RNA, proteins, cell organelles.
The fats present in milk does not mix well due to difference in their densities with the other parts of the milk. The fats in milk has a lower density than the other compounds present in the milk.
Therefore, the correct option is A.

Consider a population of Clostridium difficile living in the human gut. Regular ingestion of an antibiotic is a selective process on the gut ecosystem. Which of the following events could be considered adaptive mutations for C. difficile in this environment? A. Acquisition of a plasmid with a gene encoding an enzyme to inactivate the antibiotic B. Deletion of the gene encoding a restriction endonuclease C. Duplication of the gene encoding flagellin D. Point mutation changing a single amino acid in a membrane transporter
Answer:Acquisition of a plasmid with a gene encoding an enzyme to inactivate the antibiotic
Explanation:
Clostridium difficile is a Gram-positive gastroimtestinal bacteria that forms spore it cause a range of diseases like antibiotic-associated diarrhea (AAD).
C. difficile genome harbors a variety of resistance genes that makes it resistance to different classes of antibiotics. Analysis conducted on C. difficile 630 genome identified genes encoding β-lactamase-like proteins and penicillin-binding proteins (PBPs) as one that mediate the resistance to the β-lactam antibiotics such as penicillin and cephalosporins this is done by an enzymes that unlocks the drug active site making the bacteria resistance to it.

A. would be a good item to add to the list of characteristics of life since there aren't any
non-living things that can do photosynthesis.
B. would be a good item to add to the list of characteristics of life because all life either
directly or indirectly gets its energy from the sun.
C. would not be a good item to add to the list of characteristics of life because not all
living organisms can conduct photosynthesis.
D. would not be a good item to add to the list of characteristics of life because someday in
the future, a non-living thing may be able to conduct photsynthesis.
E. Is currently one of the characteristics of life
Answer:
Is currently one of the characteristics of life
Explanation:
One major characteristic of life is nutrition. Nutrition refers to the process by which a living organism obtains its food.
Photosynthesis belongs to the kind of nutrition called autotrophic nutrition. Autotrophs are living organisms that produce their own food from simple inorganic chemicals.
Hence, only living organisms can undergo nutrition and it is already one of the characteristics of life.
