Using the mammalian pentadactyl limb as an example, outline the process of adaptive radiation. [2 marks] Outline the causes of variation in one example of continuous variation in humans. [5 marks] Explain how evolution occurs and which factors can cause the process to be rapid. [7 marks] Ce...
Whole-genome duplication (WGD) occurs often during tumorigenesis and is associated with intra-tumoral heterogeneity22,23,24,25,26, therapeutic resistance and poorer outcomes27,28,29. WGD increases the number of copy number states that chromosomes may adopt and may also buffer against mutation of ...
Fall 2003, and Winter 2003 semesters. Most (92%) of the students were under 23 years of age. Introduction to Biological Anthropology is a large (150–200 students per semester) sophomore-level course that fulfills UMC’s Biological Sciences general education ...
the brittleness index are proposed by considering the pre-peak failure energy and post-peak fracture energy, which are regarded as key factors in determining whether brittle failure of rock occurs. By taking the Longmaxi Formation shale as an example, the energy evolution laws of shales under ...
This work reviews the long-term evolution of the atmosphere of Venus, and modulation of its composition by interior/exterior cycling. The formation and evolution of Venus’s atmosphere, leading to contemporary surface conditions, remain hotly debated topics, and involve questions that tie into many ...
We specifically argue that self-domestication can account for some of the cognitive changes, and particularly for the behaviors conducive to the complexification of music through a cultural mechanism. We hypothesize four stages in the evolution of music under self-domestication forces: (1) collective...
The phase-field method is a numerical technique implementing the Cahn-Hilliard equation and other relevant kinetic equations to simulate the microstructural evolution of materials. From: Materials Kinetics, 2021 About this pageSet alert Also in subject area: EngineeringDiscover other topics ...
Humans, and many other species, are host to diverse symbionts. It is often suggested that the mutual benefits of host-microbe relationships can alone explain cooperative evolution. Here, we evaluate this hypothesis with evolutionary modelling. Our model
答案解析:原文只是提到效果定律所提出的时间,而没有解释其时代背景或者理论背景如何。题干中when psychologists were seeking a scientific reason why creativity occurs的说法属于无中生有,因此判断答案为NOT GIVEN。 第34题答案:YES 对应原文:第9段:Law of Effect involves an entirely mechanical process of variatio...
(EB) model, where the greatest phenotypic divergence occurs early in the tree63. This step required the random resolution of soft polytomies (via the 'multi2di' function of the same package). Simulation-based studies have highlighted the importance of incorporating an estimate of error in ...
