The answer should be A, inside the bag.
Permeable means allowing certain material to pass through. So if it's permeable to water and iodine, it means it can allow water and iodine to pass through the bag, but doesn't allow starch to go in.
Because iodine can pass through the bag, it can get into the bag filled with starch. But since starch couldn't diffuse out of the bag, the color change is only can be observed inside the bag. When no starch is gone out from the bag, there is no color reaction in the rest of the beaker.
So that answer is A.
Answer:
Codominant- traits don’t have a clear dominant or recessive
incomplete dominance- the heterozygous condition shows a “blending” or a “middle” condition
Explanation:
In codominance, the traits are expressed equally in the phenotype thus they don't have a clear dominant or recessive state. For example the ABO blood group alleles. The alleles A and B are codominant each being expressed equally.
In incomplete dominance the traits show intermediate expression where one allele expresses itself more strongly than the other. An example in man is seen in the inheritance of the disease sickle cell anaemia. Heterozygote who carry the sickle cell gene are said to have sickle cell trait and as such the carrier allele (HBa) has a stronger influence on the phenotype than the dominant alle (HBs).
Answer: <em>D. Causes an accumulation of lipids in brain cells</em>
Explanation:
Tay-Sachs disease is caused by a genetic mutation in the <em>HEXA</em> gene. It is an autosomal recessive disease that causes the mutation on an enzyme, which metabolizes <em>GM2 Ganglioside</em> in nerve cells, this leads to a build-up of the molecule in brain cells. At the moment there is no cure for the disease, only support treatment is available.
B
The wastes are radioactive and can cause cancer. This is the #1 reason according to my research why it is important to dispose of nuclear waste.
