Step by step
Solved in 2 steps
- Describe why bilateral symmetry can be considered an evolutionary consequence of triploblastiaEnlist the order of endopterygota division with one example of each. explain briefly.Differentiate analogous structures from homologous types. Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a. For each cell, write either AS for analogous structures, or HS for homologous types. Note (not all structures encountered need to be here).
- The Amoeba cell exhibits specialized abilities that enable it to react to a stimulus by producing a response or a behavior. It can do this because it has adapted properties exhibited by simpler more primitive cells. These cellular properties include a) Separation of the fluid environments inside and outside the cell. b) Active transport of Na+ out of and K+ into the cell, c) diffusion of Na+ in to and K+ out of a cell in reaction to a stimulus, d) the stimulus interacting with a receptor site in a membrane embedded protein, e) All of these are true.identify the type of trichome present in: -Phoenix sylvestris-Cassia obtusifolia-Bauhinia anguinafor the organism Polyommatus eleniae Use this link to answer the following: https://www.iucnredlist.org/species/173273/6983441 Name your family and provide a description of the family including: Which Phylum does this family belong to? How many members are there in this family? What is the geographic distribution of the family? What’s special about them - list up to three unique characters found in that family.
- Multicellularity has evolved multiple times in different lineages on Earth. What is one major advantage of multicellularity over unicellularity? Multicellular organisms can move faster than unicellular organisms Multicellularity allows for specialization of cells into different tissues and organs Multicellular organisms have higher fitness than unicellular organisms. Multicellularity allows organisms to reproduce more rapidly. Only multicellular organisms can reproduce sexually.What type of symmetry is found in Cnidaria?Volvox carteri, an volvocine alga, has approximately 2000 somatic cells and only 16 reproductive or germ line cells. The observation that multicellular individuals, like Volvox, have a much smaller subset of germ line cells compared to somatic cells appears to be general rule. Which of the following is the best evolutionary explanation for why this is the case? A) Organisms can biologically only contain a small number of germ line cells as they are always larger than somatic cells. B) Multicellular individuals with a germ line vs. somatic cell line differentiation only evolved a single time, thus all members of this lineage share the same scheme of more soma cells with a much smaller subset of germ line cells. C) Having a smaller subset of reproductive cells helps reduce the likelihood of cheating from evolving, which in turns prevents the collapse of the multicellular individual system. D) None of the above.
