To define:
The term 'Cheliped', 'Swimmeret', 'Chelicera', 'Pedipalp' and 'Spinneret'.
Introduction:
Arthropods incorporate a staggeringly diverse group of taxa, for example, bugs, scavengers, insects, scorpions, and centipedes.
Explanation of Solution
Cheliped:
One of the enormous specific chelate appendages of a scavenger, as the extraordinary hook of a lobster, adjusted to shape a prehensile as opposed to a natatorial organ.
Swimmeret:
One of the combined stomach extremities of certain sea-going shellfish, for example, shrimp, lobsters, and isopods. Swimmerets are ordinarily found on the initial five stomach fragments and regularly end in combined oar like branches.
Chelicera:
Chelicera relates to any of the two of every a couple of extremities that emerge from portion two of chelicerates. They are ordinarily found in front of the mouth. Most chelicerae are comprised of three areas aside from insect chelicerae that are contained just two segments.
Pedipalp:
Pedipalps are the two limbs on the facade of an arachnid's head. A few insects appear to have ten legs and not eight, in light of the fact that these pedipalps resemble an additional pair of legs. The pedipalps are utilized rather like arms. Bugs frequently use them to hold creepy crawlies (for example crickets) for them to eat.
Spinneret:
A spinneret is a silk-turning organ of a bug or the hatchling of a bug. Some grown-up insects likewise have spinnerets, for example, those borne on the forelegs of Embioptera. Spinnerets are as a rule on the underside of an arachnid's opisthosoma, and are regularly divided.

- Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group? A) A, B, C, and D B) C and D C) D, E, and F D) E, F, and Garrow_forward
- Molecular Biology Question. Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures? Have a good day!arrow_forwardUsing the data provided on the mean body mass and horn size of 4-year-old male sheep, draw a scatterplot graph to examine how body mass and horn size changed over time.arrow_forwardPlease write a 500-word report about the intake of saturated fat, sodium, alcoholic beverages, or added sugar in America. Choose ONE of these and write about what is recommended by the Dietary Guidelines for Americans (guideline #4) and why Americans exceed the intake of that nutrient. Explain what we could do as a society and/or individuals to reduce our intake of your chosen nutrient.arrow_forward
