Urbanization has changed literally everything over the years from the environment being destroyed little by little but also it effects water pollution and by factories being made puts a bunch of terrible greenhouse gasses that are not healthy to breath in.

The process that tend to reduceb the variety within a population is called B. Random fertilization.
Answer:
0.7
Explanation:
Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.
p² + pq + q² = 1 and p + q = 1
where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then
the fitness of the green/green homozygote = 1 - 0.3 = 0.7

<u>Answer:</u>
Q: Which skeletal system <u>disorder</u> might she be suffering from?
A: <u>Osteoporosis</u>
Q: What <u>techniques</u> could be used to diagnose her condition?
A: <u>Bone mineral density (BMD) test</u> or <u>dual energy X-ray absorptiometry (DXA) scan</u>
Q: What treatments are available?
A: Medication, healthy food.
<u>Explanation:</u>
<u>The vertebral discs between vertebrae could shrink with age</u>. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to <u>osteoporosis</u>.
A <u>bone mineral density test</u>, also known as <u>dual energy X-ray absorptiometry</u> scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses <u>X-rays</u> to measure the content of calcium and thus strength of bones.
A person who is already suffering from osteoporosis should be treated with <u>medicine</u> right away so that it <u>stops</u> further <u>deterioration of the bones</u> and <u>avoid any future bone fractures</u>. Further, it can be handled by <u>eating a healthy diet</u> and <u>supplements</u> such as <u>vitamins D</u>. In case some of the bones/vertebrae are <u>already fractured</u>, <u>surgical approaches</u> might be necessary.
