Deep ocean anglerfish have special organs that utilize chemical energy to produce light that the fish uses to capture prey. The

light is then lost to the fish. Explain why this phenomenon does not violate the Law of Conservation of Energy.

<u>Answer:</u>

<em>Deep sea anglerfish makes use of bioluminescence to attract prey as well as potential partners and this doesn’t violate the law of conservation of energy. </em>

<u>Explanation:</u>

<em>Deep sea anglerfish</em> lives at very big depths under the sea and thus there is hardly any light available at these depths. The <em>anglerfish depends on bacteria</em> for luminescence since it cannot produce light on its own. Thus it maintains a <em>symbiotic relationship with the photobacteria. </em>

There is no violation of energy conservation law here. The light energy is not produced from nothingness but from the bacteria. There is no <em>creation of energy or destruction of energy in this case. </em>

Which of the following is the most characteristic feature of clastic
marusya05 [52]

The most characteristic feature of clastic  sedimentary rocks is "stratification".

<u>Answer:</u> Option A

<u>Explanation:</u>

"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.

It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.

Which hormone does the sympathetic nervous system release to increase heart rate.
sertanlavr [38]

The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.

<h3>What is a heart rate? </h3>

it is the number of contractions of the heart per minute.

<h3>What are catecholamines?</h3>

These are the neurotransmitters that have a catechol and a side chain that is an amine.

<h3>Which catecholamines are released by the sympathetic nervous system?</h3>

Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.

<h3>Where are these hormones released?</h3>

These hormones are released in the blood.

<h3>How does this hormone increase the heart rate?</h3>
  • "These hormones are released at the neuromuscular junction of the cardiac nerves."
  • "They shorten the repolarization period."
  • This speeds up the rate of depolarization and contraction and thus the heart rate is increased.

Will more air inside a basketball make it bounce higher?
marysya [2.9K]

The outcome variable, test variable, and controlled variable for each question is as follows:

  • outcome variable = bounce height; test variable = volume of air, and  controlled variable = basketball
  • outcome variable = cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth
  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine
  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight
  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight
  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper
  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

<h3>What are variables in an experiment?</h3>

A variable is any factor in an experiment that can be manipulated, controlled for, or measured.

There are three types of variables in an experiment:

  • Dependent variable or outcome variable
  • Independent variable or test variable,
  • Constant variable or controlled variable

The Dependent variable or outcome variable depends on changes in the independent variable.

An independent or test variable is the variable that stands alone and is not affected  by other factors in the experiment.

The constant or controlled variable is unchanged.

The outcome variable, test variable, and controlled variable for each question is as follows:

1. Will more air inside a basketball make it bounce higher?

  • outcome variable = bounce height;  test variable = volume of air, and  controlled variable = basketball

2. Do ''green'' cleaners clean as well as store bought cleaners?

  • outcome variable cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth

3. Which colors of fabric absorbs most heat?

  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine

4. Do bigger seeds make bigger plants?

  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight

5. Does sugar added to water improve cut flower freshness?

  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight

6. How do differences in surfaces affect the adhesion of tape?

  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper

7. What ratio of vinegar to baking soda produces the best chemical volcano eruption?

  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

In conclusion, changes done to the test variable results in changes in the outcome variable.

Explain how the taiga is different from the other forest ecosystems.
serg [7]

Taiga is a winter type forest. Taiga is different then other ecosystems because other ecosystems are not has cold has Taiga. Taiga ecosystems can get has low has -70 °F (or -60° C)

But Taiga ecosystems can get has hot has 104°F (or 40°C)

Taiga ecosystems can get colder then tundra (which is another very cold too)

Some things that make the Taiga ecosystems unique is:

  1. Evergreen trees, the Taiga is COVERED with these.

Hope this helps!

Any extra info can be provided!
