Answer:
the sample contains starch and starch is stored in ground tissue.
Explanation:
It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.
This process can simply be demonstrated by simply following these steps.
* Take two potted plants of the same kind.
* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.
* Take one leaf from each of the plants.
* Put few drops of iodine solution on each of the leaves.
* The leaf kept in the sunlight will turn blue-black due to presence of starch.
* The leaf kept in the dark will not turn blue-black because of absence of starch.
In conclusion, the iodine is used to test for starch.
Environmental change has to do with any kind of alteration that occurs in the natural environment.
<h3>What is environmental change?</h3>

Answer:
A.
half of its genetic material from each parent.
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
C. Genetic variation
Bacteria are very numerous, and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
