<span>She is at an increased risk of osteoporosis. Girls who first experience menarche at later ages are more disposed to having a lowered bone density and osteoporosis later in life. This is due to having a reduced peak bone mass, which can increase the risks of fracture.</span>
1.The trait is recessive. This means both your parents were carries, but did not show the trait. For example, B represents the allele, you're parents would have to both be Bb. This means that they are carriers, and you could have inherited either BB/Bb/bb - you actually inherited bb, which means because its a recessive trait you will show the trait.
2. For your children, it depends on who you have them with. Because you're bb, you will definitely pass on the b allele, so any child you have would be a carrier and could potentially have the trait. If you have a child with someone BB, all your offspring will be Bb (carriers- as the kid gets one allele form each parent). If you have a child with someone who is bb, all your kids would definitely have the trait. However, if you have a child with someone who as Bb, then the four outcomes are Bb Bb bb bb, so there would be a 50% chance of your kid having the trait.
Hope this helps!! :)

Today, any environment surrounded by other ecosystems that are unlike it is subject to Wilson’s theory of island biogeography. Because they are geographically isolated from other related ecosystems, these ecologies are referred to as "islands." Waterbodies divide tropical islands, but this idea also takes into account mountaintops, caverns, and other isolated ecosystems.
<h3>
What is Wilson’s theory of island biogeography?</h3>
- The biologist Edward O. Wilson and environmentalist Robert MacArthur published The Theory of Island Biogeography in 1967. It is widely considered as a foundational work in the ecology and biogeography of islands. The book was reissued by the Princeton University Press in 2001 as a volume in their "Princeton Landmarks in Biology" series.
- The hypothesis that insular biota maintain a dynamic equilibrium between extinction and immigration rates was made more well-known by the book. An island's pace of new species immigration will decline as the number of species increases, while the rate of extinction of native species will rise.
- Thus, MacArthur and Wilson anticipate that there will come a point of equilibrium where the rate of immigration and the rate of extinction are equal.
