Answer:

Cyanobacteria.

Explanation:

Cyanobacteria are simple, prokaryotic organisms that belong to kingdom Eubacteria. These bacteria are able to perform photosynthesis to get their energy and to produce oxygen.

They are also known as blue-green algae, due to their color. They are most primitive photosynthetic organisms.

Thus, the correct answer is 'cyanobacteria.'

For each of the following 6 scenarios, identify each of the following: unconditioned stimulus, conditioned stimulus, uncondition

KIM [24]

Explanation:

The unconditioned stimulus is a stimulus that naturally, and automatically triggers a response. For example, the smell of your favorite food may make you hungry. The smell is the unconditioned stimulus.

The unconditioned response is the unlearned response that occurs naturally in response to the unconditioned stimulus.

In the example above, the unconditioned response is the hunger felt.

The conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.

1. An individual receives frequent injections of drugs, which are administered in a small examination room at a clinic. The drug itself causes increased heart rate but after several trips to the clinic, simply being in a small room causes an increased heart rate.

UCS = Injections; UCR = increased Heart Rate caused by drug CS = Small Room similar to the room at the clinic; CR = Increased heart rate.

2. For 3 years Mariah has played her trombone at the school's sports stadium most Friday nights for various sporting events as part of the school's pep band. One Friday night Mariah begins to walk down the school's tall stadium bleachers with her trombone and she trips and falls down several stairs bruising her leg and feelings humiliated as the people around her look at her and some students even laugh. Ever since that incident, each time Mariah walks down the bleacher stairs she looks to see who is around her and her heart rate increases as she nervously walks down the bleacher stairs.

UCS = Being laughed at; UCR = Feeling humiliated; CS = Walking down the bleacher; CR = Heart rate increase and nervousness

3. Before she got her driver’s license, seeing police cars and their flashing red lights did not bother Jaci. But then she started driving and has been pulled over several times for speeding. Each time she was pulled over, first she saw the flashing red lights of the police car. Then she would be questioned by the police and given a ticket, which made her feel very tense and upset. Now whenever she sees a police car with its flashing lights on she feels a little bit nervous, even if it is pulling over someone else.

UCS = Given a Ticket; UCR = Tense and Upset; CS = Seeing any Police Car; CR = Nervousness

4. Frankie eats fried chicken that has e coli in it from her elementary school’s cafeteria and ends up vomiting for hours that night. Luckily, she recovers within a day, but now just the thought of eating food from the school’s cafeteria makes her nauseous.

UCS = Eating chicken with E-Coli; UCR = Vomiting; CS = Thought of eating food; CR = Nausea.

5. At a soccer game, every time the home team scores a goal, the fan behind you screams "GOAL" near your ears causing you to wince. Unfortunately for you, the home team scores frequently. As the end of the game nears, the home team scores a goal, and even though the inconsiderate fan behind you has left, you still wince.

UCS = Scream near ears; UCR = Wince; CS = Fan Shouting every time a goal is scored; CR = Wincing whenever a goal is scored

6. Casey goes outside to play in her tree house. A swarm of bees has nested near her tree house, and she gets stung when she climbs up to the tree house. This happens 3 times in a week. Casey becomes afraid to go near the tree and cries violently when her dad tried to get her to climb up to the tree house.

UCS = Getting stung; UCR = Pain (fear of getting stung); CS = Tree house; CR = Fear of Tree House.

Summarize the process of the water cycle.

Law Incorporation [45]

Answer:

Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.

kondor19780726 [428]

Answer:

b. water molecules are strongly cohesive

Explanation:

Water is highly cohesive and clumps together into drops because of its cohesive properties. Water molecules attracting each other result in surface tension, which causes raindrops to form round beads as they fall on a surface.

Know the differences between the littoral zone and the benthic zone

Olin [163]

Answer:

Littoral Zone:

The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. The littoral zone always includes this intertidal zone, and the terms are often used interchangeably. However, the meaning of littoral zone can extend well beyond the intertidal zone.

Benthic Zone:

The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud.
