Why was iodine able to diffuse across the membrane while starch was not?

Biology

Starch cannot diffuse across the membrane because starch molecules are too large to fit through the pores in the dialysis tubing, whereas iodine is a smaller molecule and therefore can diffuse across.

Answer:

The correct reason would be their size difference iodine are small while starch molecules are large to pass through the membrane.

Explanation:

The permeability of the membrane also depends on the size of the molecule. The large molecule can not pass even though all other conditions are in their favor. For example Iodine molecules are small enough to go through the membrane freely, however starch molecules are too large and complex to pass through the membrane.

Thus, The correct reason would be their size difference iodine are small while starch molecules are large to pass through the membrane.

How does water filtration work?
krok68 [10]
water filtration systems work by capturing undesirable elements in the water and allowing only clean water through. Water filtration systems for residential use that use actual filters, such as the thin film composite in reverse osmosis, do this by using microscopic pores that block even small bacteria while letting water through. Others work through other materials such as activated carbon or sand, which essentially scrubs the water clean.

How many genotypes are in the ABO+/- system?
Vinil7 [7]

Answer: There are six genotypes in the ABO blood group system and three genotypes in the Rh +/- system.

Explanation: The ABO system is a system of blood group based on the type of antigens present in the red blood cells. There are basically four types of blood groups: A, B, AB and O. Blood group A has A antigen, blood group B has B antigen, blood group AB has A and B antigens while blood group O has neither A nor B antigen.

The possible genotypes for these blood groups are AA, AO, BB, BO, AB and OO. Blood group A has two possible genotypes: AA and AO. Blood group B has two possible genotypes: BB and BO.

Blood groups ==> Genotypes

A ==> AA, AO

B ==> BB, BO

AB ==> AB

O ==> OO

The Rh+/- system is the second most important blood system after the ABO system. Rhesus factor was first discovered in rhesus monkey. Rhesus factor inheritance is independent from the ABO blood groups. An individual can either be Rh + or - based on the presence of rhesus antigen in the red blood cells.

Genotypes for the Rh factor are +/+, +/-, and -/-. Individuals who are rhesus positive will have either +/+ or +/- genotype while individuals who are rhesus negative will have a genotype of -/-.

Rhesus factor ==> Genotypes

Positive ==> +/+ (homozygous),

or +/- (heterozygous)

Negative. ==> -/-

What does transcription produce
kow [346]

Answer:

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the original DNA sequence. The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.
