Natural selection is the key mechanism of evolution and accounts for the commonality and diversity in nature. Can you give a specific example of a successful species and unsuccessful species adapting and not adapting respectively to their environments and why their adaptations or lack of made it so?
How can having high levels of serum sodium ions (high salt diets) contribute to the disease of hypertension (high blood pressure). Describe how these high levels of sodium ions can increase blood volume resulting in a rise in blood pressure.© BrainMass Inc. brainmass.com October 24, 2018, 7:41 pm ad1c9bdddf
2 species, one successful and one not so successful. Well we take the successful first, ourselves Homo Sapiens. We have an immense talent for adaptation, mainly by using our big brains and hands and our art of technology. The original natural habitat of ours were the African savannas close to the Equator. Most of us now live elsewhere on all continents of the Earth including Antarctica where apart from along the coasts no other mammal naturally lives. Without clothing (definitely a ...
The 12 science processes used in science experiments are divided into two groups:
(1) The basic processes include:
(2) The integrated processes include:
(a) identifying and controlling variables
(b) formulating and testing hypotheses
(c) interpreting data
(d) defining operationally
(f) constructing models
ii) Create a chart listing each process, the definition of each process, and one example of a science activity for each, in which a teacher can engage the students.
How do these processes support inquiry learning? What role does the teacher's attitude factor in the students' view of science?
iii) One or more of the twelve science processes are embedded in science experiments/lessons. Select a completed science lesson plan available online that includes students interacting through group work or individual experiments.
(1) suggested Web sites, identify any of the 12 science processes you recognize within that written lesson. You will bold the recognized process within the lesson plan, and label the corresponding process. All 12 processes may not be evident in one lesson plan.
(2) Include the lesson plan that you have used for this assignment.
