Consider this northern site of primary succession following the retreat of a glacier. As we move from left to right, describe some improvements in the abiotic factors that support plant growth. A) change in climate over time B) less competition for water resources due to biodiversity C) improved soil quality: increased humus and water retention D) increased population density resulting in decreased pathogens

Answer: C. improved soil quality: increased humus and water retention.


An ecological succession brings change in the type of living species residing in an ecosystem with respect to changes that occur in the abiotic (non-living factors) with respect to time.

A region affected by a retreating glacier will not be suitable for the growth of living species. The soil may be lacking minerals and will be in the permafrost condition. So for the initiation of succession the improvement in soil an important abiotic factor is required. The improved soil quality will allow the accumulation of organic and inorganic minerals by physical and biological processes. This will help in formation of humus and water retention.

Describe how hibernation has helped bear species survive. Compare the needs of the organisms to the traits.

It's helps them survive throughout winter and thrive without food during winter too. Before they go into hibernation they consume a large amount of food which helps their heartbeat slow down. Other animals that don't hibernate have their source of food during the winter too, which is the reason why they don't hibernate.

Why could humans not travel to a planet in the solar system Kepler-186f?

Though I don't know if I'm fully correct in my answer. I would say it is because we have not created a fast enough way to travel that distance and we have of course not made the technology to inanimate a person for long periods of time while keeping them completely in tact. Since humans can only live to a certain degree and it takes far too long to reach a planet in that solar system. While also the resources need for human survival would run out before making it as well, most likely.

Which characteristic cannot be inherited? A.the ability to win a soccer game B. length of fur in dogs C. shape of ears in pigs D. height of stem in a sunflower plant


A.the ability to win a soccer game


The ability to win a soccer game is not an inborn trait, it is learned behavior which is acquired through regular practice so it will not be inherited in the next generation. The off-springs of a trained and competent soccer player will not be born with the ability to play and win the soccer. If they want to be a good soccer player they too will have to work hard for it. While other traits like length of fur in dogs, shape of ears in pigs & height of stem in a sunflower plant are the traits which are inherited from the parents through genes. So, the progenies of such parents will not have to work hard to develop these traits in their body. They will be like that naturally.
