Length

types of behaviors and the length of AR-CAG repeat lengths in males. From a geneticist view, it is hypothesized that the shorter the CAG repeat length, the more AR activity there will be. The androgen receptor, AR, is activated by testosterone or dihydrotestosterone. These hormones control the development of male characteristics. Higher levels of testosterone have been linked to aggressive behavior in numerous studies. The length of the CAG repeat…

Purpose The purpose of this lab is to discover if the theory that the proportions that Vitruvius has set out for us are accurate. This lab will test the theories that Vitruvius has set out. This will also test the measuring skills and mathematical skills of the data taker. Background Information Vitruvius’ idea that a lasting idea of beauty could be learned from the 'truth of nature', that nature's designs were based on universal laws of proportion and symmetry. Vitruvius thought that the…

class? Variables: Manipulated variable: The length of the head circumference, arm span, hand span etc. Responding variable: The experimenter has different people to measure Controls: The procedure, materials, classroom Hypothesis: If I measure the foot length of my partner and me then our foot length will differ greatly by cm. Materials: Meter stick, pencil, paper, people Procedure: Measure the circumference of the head,arm span, hand span, length of the foot. Observation: Head…

Due to the fact, that the increase of radicle length within lentil bean seeds was affected by the environmental aqueous solutions, which was made up of either a table sugar, dextrose or a control. It presented that there was not a statistical difference between the table sugar or dextrose aqueous solutions in comparison to the radicle lengths since the P values were less than 0.05. Although, there was a statistical increase in radicle length with the comparison to the control. If these seeds…

Introduction Hemicentetes semispinosus is a species of tenrecs found on Madagascar that possess black and yellow quills. The trait of the species that is believed to be an adaptation are the quills because the length of the quills vary by 8-15mm (Cho et al. 2012), are barbed and can be detachable, which could indicate that it is used for defense against predators, such as viverrids, owls and boas (Eisenberg & Gould, 1970). Their behaviour also suggests that it is used as a line of defense…

trait due to the variety of horn lengths and sizes in Bovids, as well as a heritable trait, due to the continual frequency in horns throughout generations, in the species of Nyala. The adaptivity and heritability of this trait can be analyzed through the natural history of the species of Bovids, observing how horns are used in combat as a sign of defense to other males of their same species (Lundrigan 1996). What is currently known on this species is how different lengths of horns are used in…

combinations of cars used to create different train lengths using Cuisinaire Rods? If so, what is it and how do you find it? Lesson Rational: In this lesson, the students will use Cuisinaire Rods to create different combinations while having different “car lengths” (individual rods) add up to “trains” (combinations) which are equal to the length of a larger car. The students will record the different combinations and how many there are for each car length and then look for a pattern by…

each type. Their total length and diameter is measured using a ruler and caliper for comparison. Any candle found to have a deviation of more than 1 mm in diameter is replaced with a new candle. All of the candle heights are recorded.…

results to the longer length of stay in the hospital but with an improved state of health of patients. A decision on whether to implement the treatment method in the hospital depends on the management board of the hospital. If the hospital is interested in the state of health of patients, a clinical pathway should be implemented. The longer length of stay due to this treatment method can be reduced by increasing the number of doctors in the hospital to ensure that the target length of stay in…

1. The honey possum has a long pointed snout, a brush-tipped tongue, reduced jawbones and muscles, and pointed incisors and canines but small peg-like teeth. It also has ridges across the roof of its mouth. Explain how these adaptations relate to the animal’s diet, which is usually a mixture of nectar and pollen. 
 Answer The honey possum’s adaptations relate to its diet because they do not need massive jawbones and muscles to eat the pollen and nectar. Their long pointed snout and brush-tipped…
