As part of a science experiment, Jose did a test for starch on a slice of apple and a slice of potato. The yellow-orange iodine solution stayed the same color when it was put on the apple, but it became black on the potato. Why did the iodine solution change color on the potato?

Answers

Answer 1
Answer: If iodine solution reacts with starch, it will change color into black.
Since the yellow-orange iodine solution stayed the same color when it was put on the apple, it can be concluded that there is no starch in the apple. On the other case, the black color of the potato suggests that there is a great amount of starch in the potato. Anyway, this does not mean that there is no starch in the apple at all. As fruits ripen, starch slowly changes to sugar. Iodine cannot react with sugar, so the black color in the apple is missing.
Answer 2
Answer:

Answer:

The iodine reacted with the potato to form a new substance.

A pond near a city park is found to be contaminated with both bacteria and excess nitrogen. The bacteria most likely came from _____, and the excess nitrogen most likely came from _____.

Answers

Excess nitrogen is brought in the pond from the fertilizer, which are ladden in nitrogen and phosphorous, and rain water or running water takes that nitrogen to the water bodies.Bacteria must have come from the sewage disposal in the pond. Sewage is rich in organic material and allows proliferation of bacteria, which is taken to the pond when the sewage is disposed in the pond.

Answer:

runoff;sewage

What is the primary source of water stored in an aquifer?Precipitation

Ocean storage

Condensation

Transpiration

Answers

Precipitation is the primary source of water stored in an aquifer. the correct option in regards to the given question is the first option.An aquifer is actually an underground layer of water thatcontains permeable rocks, gravel, sand etc. the water can be brought to thesurface by making a water well. Hydrogeology is the study of aquifers and theway of water flow in the aquifers. The depth of the aquifers differs from areato area and the aquifers that are closest to the surface are used for drinkingand irrigation purposes.



Precipitation is the primary source of water stored in an aquifer.

Precipitation process entails the formation of clouds as a result of water vapor condensation into bigger droplets of water.

The final process of Precipitation is when its falls back to the Earth.

Hence, the process of Precipitation is the primary source of water stored in an aquifer.

Therefore, the Option A is correct.

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant characteristic. The flower color trait in radishes is an example of which of the following?
A) a multiple allelic system
B) sex linkage
C) codominance
D) incomplete dominance
E) epistasis

Answers

The answer is D) incomplete dominance.

Incomplete dominance occurs when heterozygous phenotype is intermediate to the dominant homozygous and recessive homozygous phenotypes. In radish flowers, purple is intermediate to white and red flowers. So, purple 
color is characteristic for heterozygous phenotypes. When dominant red flowers are crossed with recessive white flowers, all offspring will be heterozygotic and with intermediate - purple color.

Final answer:

The flower color trait in radishes, as described in your question, is a classic example of incomplete dominance, as the offspring's phenotype (purple flowers) is a blend of the parental traits (red and white flowers).

Explanation:

The flower color trait in radishes, as described in your question, is an example of incomplete dominance. In incomplete dominance, neither allelic version of the trait is completely dominant, resulting in an offspring phenotype that is a blend of the parental traits.

In your presented case, neither the red flower trait nor the white flower trait is entirely dominant, which is why a cross between a red-flowered and a white-flowered radish produces all-purple offspring. This is a classic example of incomplete dominance in biology.
