Answer:
Homoestasis keeps our body healthy by maintaining its temperature.
Explanation:
Going for a long walk on a hot day will stimulate thermoreceptors in your skin in response to heat and send nerve impulse to the hypothalamus in your brain causing it to release the hormone oxytocin. Oxytocin will stimulate the sweat glands found in the dermis (skin layer) to release stored water. Water will then evaporate through the skin pores, cooling you and maintaining the temperature within its normal healthy range.
1st law of motion. AN object in motion stays in motion unless acted upon.
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
