Answer:
Plant A listens to classical music for three hours each day
Explanation:
- Music affect plant growth of plants through the vibrations that it creates to the sound waves.Classical music causes more pressure to the sound waves causing vigorous vibrations which is picked up by the plants speeding up the protoplasmic movement in the cells.
- The vibrations causes movement of the plant cells which speed up growth of the plants by stimulating the plants to produce more nutrients enabling them to germinate having more leaves,greater in size and other improved characteristics which means the plant's genetic chromosomes were changed.
- Also in the soil is able to produce good fungi and bacteria encouraging better root development due to healthy vines resulting to vigorous growth and better fruit.
- Moreover the plants are able to receive special attention and care from the farmer thus enhancing faster growth.
Explanation:
Plant) Banana
Trait: Smaller seeds, larger fruit, thinner skin
People breed plants to gain desired produce with more yield. After years of genetic nurturing, the perfect bananas were created with smaller seeds, larger sizes, and an offspring with greater abundance for maximum profit.
Animal) Chihuahua
Trait: Smaller size
Chihuahuas are a great example of artificial selection in a domesticated animal because over time people successfully breaded different dogs to acquire the size of the chihuahua.
Pioneer species are found in area's undergoing secondary succession. For example ecosystems being established by: reducing a fire, deforestation; which quickly colonize open spaces supported by vegetation.
Answer:
After several hours, both beakers are expected to have the same temperature of 65°C
Explanation:
Given that:
The temperature in beaker A = 80°C
The temperature in beaker B = 50°C
The copper rod used to connect allows transference to heat and temperature from beaker A to the beaker B because it is a good conductor of heat and electricity. After several hours, movement of heat and the temperature have occurred and they have both reached equilibrium.
Therefore, after several hours, both beakers are expected to have the same temperature of 65°C
i.e.
= ((80 + 50)/2) °C
= (130/2)°C
= 65 °C
