Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question.
Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________.

- Hello! I am a 7th grade science teacher. I have 16 students, and I was wondering if this app was good enough to get the premium package for my students. If you solve these questions below correctly, I will buy the premium package for my 16 students. (Picture below) IMPORTANT: Give 1-3 (7th grade science info) good sentences explaining why you picked your answer.) (I don’t want collage/high school information about migration.

Include a description of the condition, possible genetic and environmental components that cause the condition as well as an explanation of why it is difficult to study multifactorial conditions.

This is a hypothesis used to explain why grandmothers tend to live longer than grandfathers. For this hypothesis to work, a grandmother will need to have an antagonistic pleiotropic mutation that extends her lifespan but also lessens her physical activities. Because grandmothers are older, so they tend to contribute less in a family. That is, grandmothers are usually a drain of resources for a family. The evolution of monthly menstrual cycle in human females is seen as an example explained by the grandmother hypothesis. None of the abovearrow_forward
- Go to the NCBI’s website at https://ncbi.nlm.nih.gov On the database dropdown menu, select “Gene” and search for “RB1.” The first entry should be on the Homo sapiens version; click the gene name. Use the information to answer the following: Go back to the RefSeq (back click once) section in the Gene Database entry for RB1. Click on “NP_000312.2” to access the protein’s amino acid acid sequence information: How many amino acids make up the RB protein? Does this value match your prediction in part d.ii.3? Scroll down to “Features.” List two examples of post-translational modifications that can happen to the RB proteinarrow_forwardThe tiny frog Paedophryne amauensis was discovered by researchers purposefully searching for the source of an unusual sound, but sometimes similarity between two species can lead scientists to accidental discoveries. A previously unknown species of wild cat was inadvertently discovered by researchers who were sequencing the DNA of a house cat–sized South American wild cat called the tigrina. The DNA analysis revealed that many alleles found in the supposed tigrinas living in northeastern Brazil are not shared with other tigrinas. This finding suggested that the northeastern cats do not interbreed with other tigrinas and are therefore a different species. What prevents the two species from interbreeding?arrow_forwardWhich of the following statements best characterizes genetic diversity in humans? 1.) There are far more genetic differences between populations/groups than there is variation within populations. 2.) Between-group differences in most phenotypic traits (e.g., athletic ability, performance on standardized tests, etc.) are mostly inherited and due to the effects of natural selection. 3.) The vast majority of polymorphisms (such as SNPs) in the genome are informative about a person's ancestry (in other words, you could get a pretty good idea of someone's ancestry by looking at their genotype at just about any random SNP in the genome). 4.) Humans have much lower levels of genetic diversity than most other animals.arrow_forward
- Using the information in the Reading file part II and textbook, answer the following questions: Whales possess vestigial organs in the form of pelvic girdle and hind limb bones. How would you explain this? How can you explain that, while forelimbs of bats and human arms are used for vastly different purposes, they do have similar anatomy? PART III.

In terrestrial mammals, the sense of smell (olfaction) involves receptor proteins encoded by a number of genes. Whales don't have a sense of smell underwater, but their genomes still contain copies (pseudogenes) of some of these olfactory genes in their genomes. Because they are still present in whales' genomes, these genes must serve some other function in whales. Whales have some vestigial features like muscles that are attached to external ears in other mammals, even though whales have lost their external ears. Humans also lost some traits (e.g., body fur) and also have some vestigial traits, such as a mechanism to cause fur to stand on end even though we are mostly hairless (i.e., arrector pili muscles that produce goosebumps). Some features like hindlimb buds and whiskers are observed…arrow_forwardThe image below shows how the Pokemon Charmeleon evolves into Charizard over generations. Pokemon fight battles in order to evolve into stronger Pokemon. When Charmeleon (on the left) wins enough battles, they evolve into Charizard shown on the right. If they don't defeat other pokemon they will stay in the form on the left. Explain why this fictional process is not a realistic representation of evolution. Refer to commonly held misconceptions as well as criteria for evolution by natural selection in your answer.arrow_forward
- Asthma is a common medical condition that is influenced by genetics and environment. In the US, appraximately 9% of adults have asthma. A recent genome wide association study (GWAS) identifieda genetic variation that increases asthma risk by S0% when a single copy of the risk variant is present in a genome. Which value below would represent the approximate asthma risk of an individual with this genetic variation in their genome? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a 59% b 50% 14.5% 9.5% e 9%arrow_forwardAn important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?arrow_forwardIn 2003, the Human Genome Project was successfully completed, determining the exact sequence of the entire human genome, which is made up of 3 billion nucleotide base pairs. The data generated from the Human Genome Project is freely available online to anyone. Many pieces of research and innovations stemmed from the HGP, allowing the identifications of 1 800 disease genes. Many of the corporations using the results from the HGP are privately funded, and research is being done for profit even though the HGP results are provided freely. State one advantage and one disadvantage of corporate funding and patenting genetic research results.arrow_forward
