Explain how bees find flowers containing the nectar they require
Kaylis [27]

Answer:

The Bees find the required nectar in the flower by the "sight as well as the odor and also they receive buzz from the floral electric field".

Explanation:

The nectar are agent that are secreted for pollination, specifically cross-pollination. Bees land into or nearer to the flower. Once they landed they use their proboscis for identifying the nectar or to pick it up. Bees also receive a buzz from the flower's electric field. After sensing that electric field, bees can now identify whether the visit to the flower will be worth or not. As we already know, that bee buzz across the flower is the quest for nectar.

Describe a way in which scientists can determine if a newly discovered object should be classified as living or non-living.
Hunter-Best [27]
<h3>Answer: Scientist can determine if an object should be classified as living or non-living cells by looking under a microscope with a slide. If the slide has cells in it, it is considered alive and if the cells contain food, water, exposed waste, and environment, it is alive. If the object or slide does not have any cells in it, it is considered non-living because for a cell to be alive, it needs cells in it.</h3>

describe the water cycle here on Earth and explain how it demonstrates the law of conservation of matter.
Nitella [24]

Answer:

Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level.

After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.

Finally, a precipitation experiment. Again, fill a cup almost full with water.

Explanation:

Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.

you're welcome!!
