Answer:

1) The cryosphere contains the frozen parts of the planet. This sphere helps maintain Earth's climate by reflecting incoming solar radiation back into space. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting.

2) Organisms like the Frilled Shark, Giant Spider Crab. Atlantic Wolffish Pair, Fangtooth Fish, Six-Gill Shark, Giant Tube Worms, Vampire Squid, Pacific Viperfish. But there are most likely archaeabacteria which are prokaryotic bacteria or single-celled organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.

3) Many different types of plant and animal communities call estuaries home because their waters are typically brackish — a mixture of fresh water draining from the land and salty seawater. This unique combination of salty and fresh water creates a variety of habitats. Estuaries are full of decaying plants and animals. This makes the soil of estuaries rich in nutrients. Because the soil is so rich, lots of different plants grow in estuaries. The plants attract lots of different animals to the estuary and those animals attract other animals to the estuary.

4) Temperature, humidity, precipitation, air pressure, wind speed, and wind direction are key observations of the atmosphere that help forecasters predict the weather. These same factors have been used since the first weather observations were recorded. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists. The three main factors of weather are light (solar radiation), water (moisture) and temperature.

13. Would you expect oxygen to form a cation or anion? How many electrons would it gain or lose? Why?
netineya [11]

Answer: C)Anion, it would gain 2 electrons to satisfy the octet rule.

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration of oxygen with 8 electrons is

O:8:1s^22s^22p^4

The cation is formed by loss of electrons and anions are formed by gain of electrons.  

In order to complete its octet and get stable, it gains 2 electrons and thus would form an anion.

O^{2-}:10:1s^22s^22p^6

Feliz [49]

Answer:

Step 3

Explanation:

I am back sorry it took me so long, I believe its Step 3 because that's were you chose your strategy, you use it in Step 4, but if its not Step 3 its Step 4

1. identifying

problem solving step: 1)__ the problem is most difficult: not in habit of asking what the problem really is; in the habit of reacting or giving up

2. representing

problem solving step: 2) __ the problem: abstract or external representation

3. strategy

problem solving step: 3) selecting an appropriate __; trial and error vs means-ends analysis

4. implementing

problem solving step: 4) __ the strategy; dependent on previous steps
