Answer:
From what I have learned over the years, it is true that carbon dioxide may spend a lot of time in 1 reservoir , however it continually cycles through the Earth's surface and through the earth's atmosphere. There is NO reservoir that serves just to only take in carbon dioxide.
Explanation:
Biology experience, I got an A in Biology. I also have studied the planets in science. i have also taken physics and chemistry.
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Answer:
A layer of pale,Sandy soil lacking clay and iron is likely to be found in horizon E
1. it can help people learn and study the organisums so if any thing bad happens it helps
2.people can tell if there is something wrong with the animals habitat system more easy than it was before
3.there a scienists that learn about animals life and eco system so they can live like polar bears are going enstinced becuase of global warming so t helps them stop it
hope this helps :)
