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.

- Directions : Select ALL the correct answers. An armadillo is a type of mammal that has a hard shell that covers the top of its body Armadillos can be found in North America and South America. A zoologis studied two kinds of the same species of armadillo Both kinds protect themselves from predators by digging and hiding in the ground. One kind has short claws, and the other has long claws. The zoologist called them short -clawed I armadillos and long-clawed armadillos Data was collected on the numbers of the two kinds of armadillos found in two locations location X and location Y Location X is covered in sand Location Y is covered in hard clay and rocks Data collected by the zoologist is shown below. Armadillo Populations Which explanations are supported by the zoologist's data? themselves in location X. Short-clawec and long -clawed armadillos have an approximately equal ability to protect Short-clawed armadillos are less able to protect themselves in the sand in location X Short-clawed armadillos are less able to protect themselves in the rocks and hard clay in location Y themselves in location Y. Short-clawe and long-clawed armadillos have an approximately equal ability to protect
- The sticky monkey flower, Mimulus aurantiacus, is a flowering shrub that grows in a variety of climates. The flowers of each plant can be either red or yellow. These colors attract different pollinators to aid in reproduction: hummingbirds primarily feed from red flowers, while hawkmoths only feed from yellow flowers. Image courtesy of M. Strisfield et al 2013. PLOS Genetics Lionsed under CC BY 4.0 Red flowers contain a red pigment called anthocyanin, while yellow flowers lack this pigment. Researchers have identified a gene involved in the production of anthocyanin. The allele R of this gene allows flowers to produce anthocyanin, while the allele Y prevents anthocyanin production. The table below compares the frequency of the RR (red), RY (partially red) and YY (yellow) genotypes in a population of monkey flowers in a certain region over 5 years. Year & }(c) RR Frequency & RY Frequency & YY Frequency 1 & 0.81 & 0.12 & 0.07 3 & 0.85 & 0.09 & 0.06 5 & 0.91 & 0.05 & 0.04 In year 6, the population of hawkmoths in the region increased. As a result, is the diversity of coloration in this population of monkey flowers likely to increase over time? A. No, because the population lacks the genetic variation needed to allow the frequency of yellow flowers to increase. B. No, because there is little color variation in the population and the hawkmoths will further increase the ability of red flowers to reproduce. C. Yes, because the hawkmoths will promote mutations in anthocyanin genes so new colors will appear in the population. D. Yes, because there is genetic variation in the population and the hawkmoths will increase the ability of yellow flowers to reproduce.
- Gregor Mendel's study of genetics helped to form an understanding of how biological traits are passed from generation to generation. According to Mendel's law of segregation pairs of alleles for each gene locus are separated and to different gametes during meiosis Further, Mendel's law of independent assortment explains that during meiosis, alleles for specific traits are separated independently of alleles for other traits. Which statement best describes how heredity is affected by the application of these laws? A. genetic variation decreases through meiosis B. genetic variation increases through meiosis C. only dominant alleles are passed on D. only recessive alleles are passed on
