Your lab group is experimenting with the diffusion of molecules across a membrane. Dialysis tubing is used as a model cell membr
Margaret [11]

Answer: the membrane channel

Explanation:

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Thus the water will move from an area of high concentration  to an area of low concentration, until the system reaches a steady state called equilibrium- after this, there will be no net movement of water. Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

The dialysis tubing mimics a semi permeable membrane; it only allows water and small molecules of iodine to cross into the bag containing starch. The tubing is impermeable to starch;  these large molecules require the aid of protein omplexes called membrane channels, in order to move across the membrane and against the concentration gradient.

A set of identical twins are together in an introductory biology class. The unit of study is DNA and its structure. The teacher
Hunter-Best [27]

In identical twins, alleles are identical and the order of the bases on the interior of the DNA molecule is identical (Options C and E). It is because genetic material is identical.

<h3>What are identical twins?</h3>

Identical twins refer to individuals produced by the same zygote cell, i.e., they are monozygotic twins.

Since these individuals are produced by the same zygote cell, their genetic material (DNA) will be identical.

Identical twins are useful to understand the exact role of genetics and environment in a given phenotypic trait.

Eating is important to your body because molecules in food contain_________ energy that cells use to produce ATP and it also sup
oee [108]


Food molecules contain chemical energy which is released when its chemical bonds are broken.

Food undergoes  digestion in the digestive system and is broken down into its monomer units. Carbohydrates, which are the principal source of energy, are broken down into glucose. Glucose is the monomer unit of carbohydrates.

Glucose then is taken up by cells and is used in cellular respiration, which involves three main stages namely glycolysis, Krebs cycle and the electron transport chain, through which a glucose molecule is processed to form at least 36 molecules of ATP.

ATP is the form of energy that cells use.
