The third time he plays Taylor Swift. When he plays Taylor Swift, Maggie immediately and starts to smile. •What is the independent variable? •What is the hypothesis? •What is the dependent variable? •Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all. What is this called?

Answers

Answer 1

Answer:

Independent variable: THE TYPE OF MUSIC PLAYED

Dependent variable: MAGGIE'S TEARS

Hypothesis: IF Taylor Swift's music is played, THEN Maggie will stop crying

Control group

Explanation:

The hypothesis of an experiment is a testable explanation given to possibly solve an observed problem. In this question, Maggie thinks Taylor Swift's music will get Maggie to stop crying, hence, one can hypothesize that: IF Taylor Swift's music is played, THEN Maggie will stop crying

Independent variable is the variable that the experimenter manipulates or changes in order to bring about an outcome. The independent variable in this experiment is the THE TYPE OF MUSIC PLAYED by Bart because it is what is changed.

Dependent variable is the variable that is being measured. It responds to the changes made to the independent variable. In this experiment, the dependent variable is MAGGIE'S TEARS.

Milhouse says Bart needs to try to see what Maggie will do if he doenst play any music At all, this is called the CONTROL GROUP because the control group of an experiment is the group that does not receive any experimental treatment i.e. the independent variable is not added.

While you were on safari, your friend got bit on the leg by a posionous snake and nearly died from excessive hemolysis. Being a true scientist, you captured the snake and analyzed its venom to understand why it caused hemolysis. You found thwo enzymes, a protease (breaks down proteins), and a phospholipase. He isolated each of these enzymes and treated red blood cells with them. He found that only phospholipase caused red blood cell lysis. He also found that, after treatment of red blood cells with the phospolipase, there was excess amounts of free phosphophorylcholine (Choline phosphate group) and free diacylglycerol (glycerol with two hydrocarbon tails). 1.) What is the substrate for phospholipase and where does it cleave

Answers

Answer:

Phospholipase is an enzyme, which is classified into phospholipase A2 and phospholipase A1.

In this case we are talking about phospholipase A2, that is why the sn-2 ester bond of glycerophospholipids will be taken as a substrate, giving fatty acids as a product, such as arachidonic acid.

Explanation:

The glycerophospholipids used by this enzyme are those found in cell membranes, these pathways are usually associated with inflammation pathways for the formation of arachidonic acid that functions as an immunological mediator.

On the other hand, it must be remembered that membrane phospholipids are amphipathic, that is, with hydrophilic and hydrophobic molecules and are responsible for balancing the internal homeostasis of the intracellular environment.

When you exercise, you get warmer. Name the process that goes on inside all the cells of your body, resulting in the production of
heat.

Answers

answer: negative feedback

explanation: negative feedback is essentially a counter action that occurs in order to maintain homeostasis within the body. if the body is too hot, it produces sweat to let off the heat (returning it to its normal temperature)

Thermogenesis is the process which produces heat in the body.

Body temperature is increased with exercise because your body's muscle moves continuously. Thermogenesis is the process through which our body's muscles, organs, and brain produce heat. Our muscles produce heat by shivering.

Hormonal thermogenesis is the process through which thyroid gland releases hormones in order to increase metabolism. This increase in the metabolism produces heat in the body and rises the temperature in the body so we can conclude that through thermogenesis our body produces heat.

what is cell theory ?

Cell theory is widely accepted view of origin of life on Earth functions,  all organisms are made of either single cells or a group of cell create tissues, organs, and organisms.

Three major hypothesis of cell theory are all organisms are made of cells, Second, cells are the building blocks in the creation of tissues, organs, and entire functioning organisms. The third is the cells can only arise from other cells or pre-existing cells.

Two scientists called Theodor Schwann and Matthias Jakob Schleiden first developed the cell theory in the year of 1839, along with  Rudolf Virchow another scientist who contributed to the theory.

Schleiden explained that the structural part of a plant was made up of cells and a crystallization process either within other cells or from the outside cells. Theodor Schwann explained that the structures of animals are composed of cells.

The modern cell theory explained some postulates like All living things are composed of one or more cells,  arise from pre-existing cells by cell division,  fundamental unit of both structure and function in living organisms.

The activity of an organism is the activity of independent cells, Energy flow observed within cells,  contain genetic material like DNA and RNA in cell nucleus and cytoplasm.

The lysosomes are the cellular organelles containing the hydrolytic enzymes which help in the metabolism of the complex and toxic compounds. The alcohol which is consumed is degraded and digested by the lysosomes which decrease the rate of digestion of the other complexes like the proteins.

in summer, what happens to the hurricane’s temperature, category, and speed as it travels across a body of water and then land?

Answers

I think it starts to get slower as soon as it starts traveling because then hurricanes wouldnt be as bad and would be long, and it could possible get worse as it travels across the water because it could be sucking up water so then it would get bigger and worse. The tempertaure will get colder because it will then start to pour and cause destruction and make it windy and very chilly.

In summer the temperature of hurricane will get colder because it will then start to pour and cause destruction and make it windy and very chilly and  it could be sucking up water so then it would get bigger and worse.

What is hurricane?

Hurricane has been defined as the conditions which has been expected in a specified area. As defined by National Oceanic and Atmospheric Administration (NOAA), it means that hurricane conditions (sustained winds of 74 mph or greater) are possible within your area and hurricane warnings means hurricane conditions are expected in an area.

The warm ocean water allows more water to get evaporate and this gives more power for the Hurricane to began. Powerful winds clash as a result of the air to move towards upwards which has light wind around the area allows it to start moving round and round with this whole process continues to make the Hurricane powerful and faster.

Therefore, In summer the temperature of hurricane will get colder because it will then start to pour and cause destruction and make it windy and very chilly and  it could be sucking up water so then it would get bigger and worse.
