Help with biology!?

Posted on February 29, 2012 by admin| 1 Comment

1. Basking sharks swim close to the surface of the water and appear to be sunning themselves like lizards. In fact, however, they are feeding on plankton. Why might a land-dwelling creature like a lizard need to sun itself, while a water-dwelling creature like a shark does not?

2. Flying foxes, the largest bats, have a wingspan of about 5 feet. The albatross, one of the largest flying birds, has a wingspan of 11 1/2 feet. Why do you think flying birds can be so much larger than flying bats? (Hint: mention at least one adaption for flying which birds have and bats lack.)

Biology question?

Posted on February 7, 2012 by admin| Leave a comment

A species of bird with three-toed feet feed mostly on worms and crawling insects. Over a period of several thousand years, the ocean level rises, and the region where the bird lives is flooded. Over several thousand years or so, the birds’ descendants evolve webbed feet and begin to feed on fish. Is this an example of gradualism or punctuated equilibrium? Explain.

Biology Question related to Evolution?

A protein similar to the mammalian hormone prolactin is found in amphibians and birds. In amphibians, such as newts, it causes the animals to seek water as they do when they lay their eggs. In birds, such as pigeons, it causes them to regurgitate material from the crop to feed their young. Mammals respond to prolactin by producing milk. How does the theory of common descent explain these similarities?
This is for my lab so it does matter, religon people leave no comment.
When I say religion people no comment im not insulting them i have my religious beliefs, i just strictly wanted a science answers

Is it bad to feed birds cooked rice?

Posted on February 9, 2011 by admin| 6 Comments

My grandama thinks its okay to feed birds cooked rice. She said that back in her days, she did it all the time. But I swear my biology teacher told me it’s bad for them. Like their stomach expands or something. But I’m not sure…so if you know the answer, I would gladly appreciate if you gave me the answer. Thanks!
