1. Phytoplankton, krill, fish, penguin

2.  Baleen whale, smaller toothed whale

3. krill

4. the phytoplankton are the producers, they make their own food from the sunlight just as plants do.

5. herbivorous zooplankton, phytoplankton

6.  One type is a herbivore it snacks on plants. The other type is a carnivorous type of zooplankton it eats smaller animals.

7. Draw a pyramid with several layers. at the bottom write phytoplankton. above that layer write zooplankton, not the carnivorous type. above that write 1st level carnivorous consumers, such as the fish, krill, other birds, and small squid. above that write 2nd level carnivores like the leopard seal, penguin, and elephant seal. Then above that write Baleen whale, smaller toothed whale, and a sperm whale.

Alyssa investigates properties of matter. The answer to which question would best
timofeeve [1]

Answer:

This question is incomplete as it lacks options, the options are:

A) What is the radius of each particle of the substance?

B) Does the substance contain more than one type of atom?

C) Was a chemical reaction necessary to create the substance?

D) What is the electrical charge of the particles of the substance?

The answer is B

Explanation:

In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.

According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?

- If the answer is yes, the substance is a COMPOUND

- If the answer is no, the substance is an ELEMENT.

1. During which process of the hydrologic cycle does the sun heat surface water, causing the water to change from its liquid sta
xenn [34]

Answer:

1. D. Evaporation

2. A. A closed lake has no outlet stream.

3. C. The angle of the slope

4. C. Granite

Explanation:

1. The process through which water changes its state from liquid to gaseous is known as evaporation. A source of energy is required for this process to occur, energy that is provided by solar heat in this case. The opposite process in which water changes state from gas to liquid, is known as condensation. Precipitation is the process in which the condensed water reaches the Earth’s surface under the force of gravity. During infiltration, water on the ground surface enters the soil.  

2. A closed lake is defined by the lack of any outflow. Thus, any water that does not evaporate, will remain in this type of lake indefinitely.

3. The only criterion not used to describe a mass movement event is the angle of the slope. For such an event, the type of motion is the most important characteristic together with the physical characteristics of the material.

4. Granite is a highly consolidated material and thus it has a very high integrity. The other materials listed have inferior characteristics.

5. Soil erosion is a displacement process that occurs naturally though the action of water and wind. On a steep slope, no soil formation occurs, because, due to gravity, all the eroded material will be transported to another location. Thus, at the slope’s location, no soil formation occurs.

Why does surface tension occur?
Kisachek [45]
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken.
