Current populations of organisms vary significantly depending on the species and ecosystem. For instance, the population of pine trees in a forest is determined by ecological factors. Total known species represent a fraction of entire biodiversity, with limitations due to resources and political will.
The current population of an organism varies greatly depending on the species and its ecology. For instance, in a forest, each pine tree is an organism and all these pine trees together make up a population. The number of individuals in this population would be dependent on various ecological factors such as availability of resources and interactions with other species.
Furthermore, it's important to note that our current knowledge of species that inhabit the planet is quite limited, and always will be, due to lack of resources and political willpower. Estimates suggest that the known eukaryote species, approximately 1.5 million, account for less than 20 percent of the total eukaryotes present on earth (around 8.7 million species, according to one estimate). For prokaryotic species, current numbers are largely speculative and scientists agree that we have only begun to catalog their diversity.

Marfan syndrome is a rare disease of the connective tissue, which affects different structures, including skeleton, lungs, eyes, heart and blood vessels.
It is characterized by an unusual increase in limb length. It is believed to affect one in 5,000 people. Unlike other genetic problems, it does not negatively affect intelligence.
Answer:
The correct answer is a. early menopause.
Explanation:
Estrogen is the hormone that helps in the protection of bones from being lost or degraded. This hormone is released in the ovary by follicle. The level of estrogen decreases sharply when a woman reached its menopause.
This decrease in estrogen levels in females can lead to osteoporosis in women. So early menopause increases the chances of bone loss in woman and bone loss increases the chances of fractures in women. One in two women who are above 50 in America breaks a bone due to osteoporosis. Therefore the correct answer is a. early menopause.
