Explanation:

The Cytomegalovirus is one of the most common viruses there is that affects humans. Humans of all ages can carry it but because the immune system is capable of fighting it, it is usually in its latent form which is the way that it is usually spread.

When the immune system has been weakened, the virus can cause conditions such as liver problems. It is spread through bodily fluids such as  saliva, respiratory mucus, milk, urine, semen, and cervical secretions.

Answer:

The answers are:

carrier proteins → charged amino acid    

Carrier proteins are transmembrane proteins for the facilitated diffusion of charged amino acids across plasma membranes.

osmosis → water molecule

A type of passive transport, osmosis is the diffusion of water molecules in and out of cells.

active transport → calcium moves from low concentration to high concentration

This is the movement of substances across membranes against concentration gradient.

simple diffusion → oxygen

Oxygen molecules enter through membrane by simple diffusion from an area of high to low concentration.

exocytosis → proteins from the Golgi apparatus  

This process of exocytosis is used by cells to release particles that has been packaged by the golgi bodies.

Explanation: Boom

Carrier Proteins is Charged Amino Acid, Osmosis implies to Water Molecule, Active Transport - Calcium moves from low concentration to high concentration, Simple Diffusion - Oxygen, and Exocytosis - Protein from the Golgi Apparatus.

In assisted diffusion, a type of transport in which charged amino acids or other molecules bind to particular carrier proteins in order to traverse the cell membrane, carrier proteins are involved.

The passage of charged amino acids through the membrane is aided by this mechanism.

Osmosis is the flow of water molecules over a membrane that is selectively permeable, caused by variations in solute concentrations.

The movement of substances against a gradient of concentration, usually from a region of lower concentration to one of greater concentration, is referred to as active transport.

In this instance, calcium ions are actively moved utilising ATP energy from low concentration to high concentration areas.

Simple diffusion is the gradient-driven passive migration of molecules from a region of higher concentration to a region of lower concentration.

Due to their small size and nonpolarity, oxygen molecules can freely diffuse through the cell membrane through simple diffusion.

Exocytosis is the process through which cells discharge big molecules, such proteins, to the exterior of the cell from the Golgi apparatus.

The proteins are contained in vesicles that join the cell membrane and discharge their contents outside of the body.

Thus, charged amino acid transport is facilitated by carrier proteins, water molecules are moved by osmosis, calcium is moved against its concentration gradient by active transport, oxygen is moved along its concentration gradient by simple diffusion, and proteins are released from the Golgi apparatus through exocytosis.

Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more. The process of theory change may take time and involve controversy, but eventually the scientific explanation that is more accurate will be accepted.

Answer: At low temperatures the fluidity of the membrane decreases and it favors fluidity. The higher the concentration of unsaturated fatty acids, the less tightly the phospholipids can bind and the more fluid (more permeable).

Explanation:

The plasma membrane is a lipid layer that delimits the entire cell, dividing the extracellular medium from the intracellular (the cytoplasm of a cell). They are composed of phospholipids, which are molecules composed of glycerol, a phosphate group and two lipid chains (such as fatty acids). Glycerol is a three-carbon molecule that functions as the backbone of this membrane. A geometry is formed that allows the phospholipids to line up side by side to form broad sheets. They are insoluble in water, but their unique geometry causes them to aggregate in layers without any energy input, as they possess a hydrophilic phosphate head and a hydrophobic tail consisting of the two fatty acid chains. The hydrophilic heads of the phospholipids in a bilayer membrane face outward and are in contact with the aqueous fluid inside and outside the cell. Because water is a polar molecule, it readily forms electrostatic (charge-based) interactions with the phospholipid heads.

Selective permeability is a property of the plasma membrane and other semipermeable membranes that allow only certain particles to pass through them. In this way, those particles that are needed by the cell can enter the cell and those that are not useful to the cell are prevented from entering. In the same way, the cell can eliminate the particles it has produced as waste. In this way, the entry and exit of substances through the membrane is regulated and the correct functioning of the cell is achieved.

For a particle to be able to cross the plasma membrane it must have a size equal to or smaller than the pores of the membrane, it must have the opposite charge to the charge of the membrane or simply have a neutral charge, and if it is larger than the pores it must be dissolved in a solution, decreasing its size and thus be able to enter the cell through the membrane.  

Plasma membranes are fluid and this fluidity depends on their lipid composition and temperature. Depending on the temperature, membrane lipids can be found in two different states or phases: gel (solid-like, with more rigid hydrocarbon chains) and liquid crystal (more fluid, with more mobile hydrocarbon chains). At low temperatures the fluidity of the membrane decreases and in these conditions the increase of its concentration favors fluidity. The temperature at which the transition from one state to the other occurs is the phase transition temperature (Tc). At values below Tc, the bilayer is in the gel state and at higher values it passes to the liquid crystal. It should be noted that there is an equilibrium between the gel state and the liquid crystal state and that the characteristics of the lipids of the bilayer condition the transition temperature. In the case of bilayers consisting of only one type of lipid, the Tc is well defined. But biological membranes are complex lipid mixtures and the transition from one state to another occurs over a range of temperatures. The presence of short-chain or unsaturated fatty acids reduces the transition temperature, while saturated fatty acids and the increase in the length of the hydrocarbon chains cause this temperature to rise. Then, phospholipids with unsaturated fatty acid tails cannot bind as tightly due to the bent structure of their tails. For this reason, a membrane of unsaturated phospholipids remains fluid at lower temperatures than a membrane of saturated phospholipids.  

The fluidity of a membrane is the ability of a molecule to move through it. In short, the higher the concentration of unsaturated fatty acids, the less tightly the phospholipids can bind and the more fluid (more permeable) the membrane will be even at low temperatures. However, at low temperatures the fluidity of the membrane decreases (lower permeability) but the effect will depend on the composition of the fatty acids. To determine the exact permeability, it is necessary to relate the concentration of unsaturated bonds and the length of the fatty acids in the phospholipids and the temperature.

Answer:

 true it consumes some ATP as well as producing it

true it produces ATP that can be directly used by cells

true it does not directly require oxygen to operate

false it produces more ATP than any of the other respiration reactions

Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.

Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.

Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

Answer:

Bacterial conjugation

Explanation:

Carbapenem-resistant Enterobacterales (CRE) are different types of bacteria that lead to infections in healthcare settings. Moreover, a plasmid is a small piece of DNA that can replicate independently from the bacterial chromosome. Bacterial conjugation is a type of horizontal gene transfer by which plasmids are transferred from one bacterium referred to as 'donor' into another called 'recipient' by sex pili. Plasmid transfer is unidirectional and depends on physical contact between bacterial cells. In this case, it is expected that this type of DNA transport mechanism occurs among patients occupying the same rooms in healthcare settings.
