Answer:

Name: Put your name, teachers name, date, and Spheres of Earth Hands on Lab Report.

Objective: To demonstrate nature in a small environment.

Hypothesis: If I kept my terrariums in the dark, then the water level will stay the same.

Procedure: I got a container for my terrarium and put in things that would normally be on Earth like plants, rocks, and water. My terrarium was perfect and looked cool.

Data:

Day 1: 3 inches

Soil: present, mostly dry.

Day 2: 2.9 inches

Soil: present, moist

Day 3: 2.5 inches

Soil: present, wet

The water level was similar in both terrariums. Some of the water evaporated each day. There was water dropplets on the lids. The soil was getting wetter as more days passed due to humidity. My hypothesis was correct because less exposure to sunlight decreases evaporation. If I was to repeat the experiment, I would use a darker place and make my observations more accurate. In real life, in caves it is very dark so there is very little humidity.

Soil, water, plants, sunlight, and sediment.

Moving water has been utilized in hydroelectric plants to _________________, but in recent years negative environmental conseque

Aliun [14]

The correct answer is D. Generate electricity.

Explanation

A hydroelectric plant is a construction in which, as its name implies, the movement of water is used to generate electricity. These are located in the cause of a river, where they dam the river water, and allow it to follow its current through a complex of tunnels where the water acquires high pressures. Later, the water meets turbines that are moved by the energy that water brings, which generates that this synthetic energy is transformed into electricity. Therefore, the option that best completes the sentence of the question is D. Moving water has been used in hydroelectric plants to generate electricity, but in recent years negative environmental consequences have been known. The environmental damages of hydroelectric plants can be alteration of terrestrial, aquatic ecosystems and their biodiversity, it also generates changes in the river regime, alteration of natural flood cycles.

What conclusion can you draw from the hereditary versus environment debate?

Cerrena [4.2K]

Answer:

There can be no conclusion drawn from the debate that whether hereditary and environment are involved in the building of the organism.

Some of the features of the organism are dependent on the environmental factors and some of the factors are related to the hereditary of the organism.

Example: The tail of the rat was cut and the next generation that was born with tail and in this case there is no role of the environmental factors on the mice.

A person has no health issues but gets affected by the nearby environment and is diseased. In this case there is no role of hereditary on the person.

So, there cannot be any conclusion of such topics. Both of the factors are equally important.

In the initial period of learning, ________ describes when an organism learns to connect a neutral stimulus and an unconditioned

Alexandra [31]

Answer:

The given blank can be filled with acquisition.

Explanation:

An unconditioned stimulus provokes the unlearned response and an unconditioned response is the naturally taking place reaction. A neutral stimulus is illustrated as the stimulus that prior to conditioning do not generate any kind of response.

A type of learning wherein a subject begins to react towards neutral stimulus as it would perform with another stimulus by acquiring the path of associating the two stimuli is termed as classical conditioning.

An acquisition can be illustrated as the time of learning in classical conditioning where an individual begins to associate a neutral stimulus with an unconditioned stimulus that further permits the neutral stimulus to begin possessing the conditioned response.

astraxan [27]

Answer:

Signal detection theory

Explanation:

Signal detection theory predicts the relationship of how well a signal is detected and the psychological state of the observer. This theory evaluates how and when the presence of a faint stimulus ("signal") amid background stimulation ("noise") is detected. Assumes that there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and level of fatigue

kipiarov [429]

I'm assuming this is referring to the Peppered Moth, a species of moth that adapted to the change of color on tree bark. The tree bark changed color as a result of local pollution. The moths (over the course of generations) changed color as well that better suited camouflage upon the new color of the tree bark.
