Answer:
major event of anaphase is the sister chromatids moving to opposite poles of cells due to action of the condensing spindle fibres.
Explanation:
the chromatids only start separating when the pressure is sufficient to split the centromere.
Answer: The integumentary system is essential in maintaining homeostasis, a state of stability across factors like temperature and hydration, in the body. The integumentary system stores water and prevents dehydration as well as producing sweat to regulate temperature and rid the body of waste products
Explanation: Barrier protection and water transport can be demonstrated with a piece of fine cloth. Pour water with coarse sand in over the cloth. The sand (bad organisms) are kept out, but the water (sweat) can go through.
Insulation: Put a thermometer into a small block of styrofoam. Put the block on a piece of ice, and then in a cup of hot water and observe the temperature. That is how the skin helps to regulate body temperature.
Cooling: When we exercise a lot (running is good) we generate more internal body heat. Notice how exercise (work) or even just hotter temperatures in the cause us to sweat.
Measure the air temperature with a thermometer and a fan blowing over it. Then measure it again with the thermometer covered with a THIN wet paper towel. That is how our sweat cools our body by evaporation.
This relationship between the plant and the animal represents mutualistic symbiosis; they have a symbiotic relationship which is mutualistic.
Plants benefit by having their seeds dispersed to farther areas when animals eat their nutritious fruits. So, animals gain from the plants since they are able to attain nourishment for themselves. Both benefit from each other at the same time when an action is done, and so, their relationship is mutual.
Hope this helps! :)
