Biology Homework Assistance

The most challenging aspect of biology education is making students grasp the microscopic realm of biology, delving into cells and exploring genes and molecules. However, with the advent of information technology, biology homework assistance can play a crucial role when neither words nor illustrations suffice to elucidate biology concepts.

QuestionAI is an online biology learning platform that aids in learning and mastering biology concepts, featuring a variety of experiments and corresponding exercises, a departure from conventional biology question aids. Here, you can simulate experiments to replicate experimental scenarios, delving deeper layer by layer to comprehend and internalise key concepts.

For the pedigree below , shaded symbols represent afflicted people. Males are squares; women are circles. If the trait is a sex-linkec I trait carried on the X chromosome, what is true about the mother represented by circle 1? She has one allele for the disorder. She has no alleles for the disorder. She has two alleles for the disorder. She has the genotype XXY.

Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have shapes and structures, including the presence of gill slits and talls. How is this comparison of the embryos used as supporting evidence of evolution? The similarities suggest that chickens and humans are the direct descendants of modern-day fish with talls and gill slits. The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of talls and gill slits.

1. Look at your Part 4 Notes on Lipids, at the top of the page in the section titled Basic Details,Use the information in that section to check the 3 statements about lipids that are TRUE. Lipids contain phosphorus and nitrogen Lipids are insoluble. Lipids are made of carbon, hydrogen and oxygen atoms. Lipids determine the type of cell that will grow and the organism that will grow from all those cells. Lipids include things that are fatty, oily or waxy. Lipids are made of amino acids Lipids determine the traits of an organism. 30 po

38. State the amount of digestion (in mathrm(mm) ) that might be expected after 48 hours in a test tube that is identical to the other 5 test tubes, but at a temperature of 15^circ mathrm(C) . (1) less than 2.5 mathrm(~mm) (2) between 2.5 and 4 mathrm(~mm) (3) between 4.0 and 7.5 mathrm(~mm) (4) more than 7.5 mathrm(~mm) 39. The best graph of the results of this investigation would be made by plotting the data on which set of axes? (1) (2) (3) (4) 40. The student repeated this same experiment using a glass tube containing potato instead of egg white. After 48 hours, he found no evidence of any digestion. Explain why no digestion occurred. [1] 41. During the winter, many fish eat very little. Some students thought this might be because less oxygen is dissolved in the cold winter wat than in the same water during the warm sum mer months. The students tested the water a found that cold water holds more dissolved oxygen than warm water. They also discover that the fish have nearly as much food avail during the winter as in the summer. Explain why the fish eat very little during winter. [1]
