Is the theory of human evolution proven? What is the strongest argument used to support evolution? What is the evolutionary outcome of genetic drift? What is the relationship between mutation, natural selection and adaptation? What does parallel evolution result in?
It is an evolutionary adaptation that allows the body to react to danger quickly. Dilated air passages, for example, allow the body to get more oxygen into the lungs quickly, increasing physical performance for short bursts of time. The blood vessels contract in most of the body, which ...
The frequency of waves is how many waves pass a given point in a specific unit of time. Frequency is directly proportional to the energy. The higher the frequency, the higher the energy. What is meant by frequency in sound? Frequency in sound refers to the number of mechanical sound waves...
What is groupthink? What is modernism? What is prosocial behavior? What is a general adaptation syndrome? What is morphological typology? What was the concept of normalcy based on? What is meant by "biological traits", and "sexual identity traits". ...
What is meant by an unconditioned stimulus (US) and an unconditioned response (UR)? In Pavlov's experiments with dogs, what were the US and the UR? 2. What is meant by a conditioned stimulus (CS) and a conditioned response (CR)? In Pavlov's experiments with dogs, what were the CS...
For now, at least, the increase is small, never much more than 10%.5Since any evolutionary adaptation comes with trade-offs (妥协), it is unclear how far the process might go. A.Therefore, climate change is the most reasonable explanation. ...
A proposed new definition might read: A mineral plant nutrient is an element which is essential or beneficial for plant growth and development or for the quality attributes of the plant or harvested product, of a given plant species, grown in its natural or cultivated environment. A plant ...
The truth, as Darwin wrote, is that “it is absurd to talk of one animal being higher than another”, and the popular conception of evolution-as-hierarchy is just plain wrong. No, what Darwin meant by an evolutionary tree is more like a map. There’s an element of time embedded in ...
What is meant by a matrix structure in an organisation? What is the difference between heredity and variations? How is the structure of a neuron linked to its function? What is a synaptonemal complex? Identify the normal structure and function of the reproductive system. ...
What is meant by natural selection? What are two factors that could limit the size of the human population? What are some examples of natural selection that have favored particular physical traits in particular populations? What are the steps in the process of natural selection?
