A study of a population of Eastern bearded dragons, Pogona barbata, found that lizards killed by a common predator, dingos, had shorter “beards” than surviving lizards. 1A. Describe how evolution by natural selection on beard length occurs in this population (, 2 sentences). 1B. Explain which type of selection is acting on beard length and why (1 sentence). How could we demonstrate that short beard length is an adaptation? ( 1-2 sentences). 1C. A researcher wants to compare beard length and its effect on predator evasion in bearded dragons. They are going to compare Eastern bearded dragons to a close relative, the Pygmy Bearded Dragon, Pogona henrylawsoni, using the comparative method. Why should the researcher include at least one more species in their study? (2sentences) 2. As an undergraduate, Marcell was required to memorize the attached phylogeny in preparation for the first midterm (and final) of the evolution course at CSULB. Fortunately, you are NOT required to know this tree. Instead, you will use it to answer the following questions in this essay assignment 2A. What phylogeny term learned in lecture would you use to describe the group containing Annelida, Mollusca, and Arthropoda? ( one word). 2B. What phylogeny term learned in lecture would you use to describe the group containing Primates, Lagomorpha, Dermoptera, and Scandentia? (one word) 2C. It may be useful to compare Monotremes to other mammals because Monotremes are the ( one word): 2D. What phylogeny term would you use to describe the internal node between Anura, Amphibia Caudata, and Gymnophiona (one word)?
Framework Review of Integumentary The patient is by all accounts a sound 64-year-old white man. The patient 's past activity history was a break and obsession of the correct lower leg 23 years back. The patient revealed that hypertension could be treated with prescription as his solitary ailment. Precise appraisal of the careful framework After looking at the dermal framework, we found that the reciprocal knees are swollen. Expanding on the two sides was estimated by estimating the boundary of the upper tibia and lower tibia of the two knees. Left knee expanding of 44.5 cm and 41.0 cm was estimated at the upper tibia and the lower tibia separately. The skin framework incorporates skin, nails and toenails, and different structures including organs. Not at all like other body frameworks of the whole body framework, the integument framework isn't restricted to one zone or territory of the body, however rather the external covering framework covers the entire body. The dermis, the center layer of the skin, contains veins, which have two sublayers, reticular and areola like sublayers, the two of which are flexible to the skin, for example, when there is growing under the skin during pregnancy Gives sex and versatility. Skin stretch Body framework comprises of outside organs, for example, skin, nails, hair and so on, to shield the body from harm. Skin is the biggest organ in the body. It comprises of three layers: the epidermis, the dermis and the subcutaneous tissues contain put away muscle to fat ratio. Nails and hair are made of protein keratin. In different creatures, the integumentary framework may incorporate quills, scales or hooves. The skeletal framework comprises of the considerable number of bones, or bones, of the human body. The skeleton frames the supporting structure of the body. It originates from the Greek σκελετός (skeletós), which signifies "dry" and means the dry idea of the bone. A human infant has 270 bones, some of which are melded to shape 206 grown-up bones. At the point when the incipient organism creates, ligament turns into an antecedent of the bone and it is found in a particular structure of the body, for example, nose, ear, joint. The integument framework is a gathering of organs that structure the body's envelope and shield it from numerous dangers, for example, disease, dryness, scraped area, concoction assault and radiation harm. In people, the integumentary framework contains a thick keratinized epithelium made out of skin, that is, a multilayered cell that is considerably water impermeable. It additionally contains extraordinary cells that discharge melanin to shield the body from bright beams and cancer-causing impacts of insusceptible cells. Sweat organs that channel squander and direct internal heat level are likewise part of the dermal framework. Somatosensory sensation and nociceptors are a significant piece of the organ framework and go about as a notice sensor to get the body far from hurtful upgrades>GET ANSWER
