What are the 4 types of adaptations? Evolution by natural selection Behavioural – responses made by an organism that help it to survive/reproduce. Physiological – a body process that helps an organism to survive/reproduce. Structural – a feature of an organism’s body that helps it to survive/reproduce. What are adaptations examples? Examples include the long […]
What is an example of red shift?
What is an example of red shift? Scientists can use redshift to measure how the universe is structured on a large scale. One example of this is the Hercules-Corona Borealis Great Wall; light takes about 10 billion years to go across the structure. How is Red Shift measured? How Do Astronomers Measure Redshift? The most […]
What is the difference between heat transfer by conduction and convection?
What is the difference between heat transfer by conduction and convection? In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. The heat transfer occurs through a heated solid object. What is the difference between conduction and convection name one medium in? hope this helps. […]
What can a child not do in the concrete operational stage?
What can a child not do in the concrete operational stage? Children gain the abilities of conservation (number, area, volume, orientation), reversibility, seriation, transitivity and class inclusion. However, although children can solve problems in a logical fashion, they are typically not able to think abstractly or hypothetically. What is a formal operational thinker? The formal […]
What is angular momentum of a particle?
What is angular momentum of a particle? The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the fundamental constraints of the conservation of angular momentum principle if there is no external torque on […]
Do you think humans are still evolving?
Do you think humans are still evolving? Takeaway: Evolution means change in a population. That includes both easy-to-spot changes to adapt to an environment as well as more subtle, genetic changes. Humans are still evolving, and that is unlikely to change in the future. What do all humans have in common? Human nature: Six things […]
Why does glass amplify sound?
Why does glass amplify sound? It happens because glass resonates at frequencies we can hear. The resonant frequency of the glass changes with its thickness. When energy at that frequency meets the glass, it causes the glass to vibrate like a drum head. How do you physically amplify sound? Untitled Document. Sounds can be made […]
What is difference between PCT and DCT?
What is difference between PCT and DCT? PCT occurs after the Bowman’s capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT. The main difference between PCT and DCT is that PCT is the function of each part in the nephron. Which is […]
