The early atmosphere of earth consists of gases such as <em>ammonia, methane, water vapour, and carbon dioxide.</em>

goldfiish [28.3K]

We can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

<h3>Why did the water vaporize and then condense?</h3>

As the water was heated by the electric heater, its internal temperature increased. Once this temperature reached the boiling point of water, the water vaporized or evaporated into a gas. This gas then reached the mirror, where it collected and cooled down, condensing back into a liquid in the form of water droplets.

Therefore, we can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

VMariaS [17]

Answer:

Porifera or Sponges

Explanation:

Porifera is the phylum of the simplest multicellular marine animals. Their body is composed of  two cell layers (something like tissues) and mesophyl between them. The body is in direct contact with surrounding water through the large number of pores and channels. What makes Sponges so simple is that their cells are unspecialized and that they  don't have nervous, digestive or circulatory systems.

BigorU [14]

This information can be useful to agriculture because bees are major pollinators of crops, so it is important to know which pesticides to manage in order to avoid risk to bee survival. That is option B.

Bees are one of the social insects that lives in societies that are based on a caste system.

Each caste performs a special task or series of tasks that serves as an economic importance to the agricultural system.

Pests such as parasitic mites cause poor agricultural yield. By using pesticides, which are protective chemicals, farmers have greatly improved crop yield.

The bee workers while in search of pollen from crops can be harmed from the pesticides that is being used to control parasitic mites. This can lead to Colony collapse disorder of the caste system of bees.

Therefore,  it is important to know which pesticides to manage in order to avoid risk to bee survival.

Each cell has a structure that separates the inside of the cell from.the environment. What cell is this?
kotykmax [81]

Answer:

Either the cell wall or the cell membrane.

Explanation:

All cells have cell membranes which line the outside of the cell, and some cells have cell walls, which also line the outside of the cell. Since all cells have cell membranes I am inclined to believe that the correct answer would be cell membranes.
