STIMULUS – RESPONSE PERFORMANCE LAB 38 points

PURPOSE: To measure response time after visual, auditory, and tactile stimuli have been practiced.
MATERIALS: meter stick or a yard stick (If you don’t have one - something about three feet long and stiff will work. You could get cardboard for example and mark off the distances on it..)




PROCEDURE:

Place your arm on a desk or table top with your hand resting on the edge. Your thumb and forefinger need to be projecting over the edge and about 2cm apart.
Your LC, friend or family member will hold the meter stick in a vertical position so that the zero end of the meter stick is halfway between your thumb and forefinger. The holder of the stick will drop it without warning you. You are to catch the meter stick as soon as possible after it has been released. Record on the data table the number of centimeters the meter stick dropped before you caught it.
Repeat the procedure 9 more times.
Repeat the procedure in steps 2 and 3 but this time close your eyes and have your LC, friend or family member tell you the moment the meter stick is dropped. Repeat this 9 more times and record the data in the data table.
Repeat the procedure in steps 2 and 3 but this time use a tactile stimulus. Have your LC, friend or family member touch you as soon as the meter stick is dropped. Be sure your eyes are closed. Repeat 9 more times and record your data.

Why did the students leave the amylase and starch solutions in the water bath for five minutes in step 3

Answers

Answer:

Each enzyme functions at an optimum temperature.  Below the optimum temperature, the enzyme's function slows, and will eventually become inactive.  Above the optimal temperature, the enzyme's activity will slow.  Too far above the optimum temperature and the enzyme becomes denatured (its shape changes) and it can no longer function.  Amylase is the enzyme that breaks starch (amylose) down into maltose.  The amylase and the starch were placed in the water bath to allow the reaction to occur at amylase's optimum temperature of 37 C.

What should scientists do when a new discovery is made that goes against a long-accepted theory?

Answers

He should analyze and compare his findings with findings already accepted within the scientific community.

What is theory?

A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.

A theory not only explains known facts as it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold the more observations it predicts, the more tests it passes, the more facts it explains the stronger the theory.

. If a substance changes form one phase to another, is it still the same substance?

Answers

Answer:

Yes

Explanation:

A phase change does not change the chemical make-up of a substance.  Phase changes are typically temperature dependent, and change only the movement and physical arrangement of the atoms and molecules in the substance.  Water, for example, is composed of two hydrogen atoms attached to an oxygen atom by covalent bonds.  That stays the same whether the water is solid (ice), liquid (water), or gas (steam).  The chemical structure of water does not change as it goes through the different faces.  It's still water.  What does change is the speed at which the molecules move and how far apart they are as a result.  Water vapor consists of molecules moving quickly and at random.  As temperature drops, water molecules slow down.  Since water is slightly polar, hydrogen bonds form between the molecules bringing them closer together.

After a forest fire, which type of organisms will begin secondary succession?.

Answers

Answer:

herbaceous plants

After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns, which require high levels of light.

Pioneering or early successional species are the kind of organisms that usually start secondary succession after a forest fire.

Thus, these creatures include grasses, herbaceous plants, and tiny shrubs that are small and have a rapid rate of growth. They have evolved to colonize and prosper in open, uncontrolled environments.

Pioneering species have developed systems that enable them to quickly germinate, develop, and reproduce while using the sunshine and nutrients that are accessible.

They support soil stability, moisture retention, and the development of additional plant species through improving environmental conditions. These early-successional species provide the way for the ultimate re-emergence of more mature trees and a complex forest ecosystem when secondary succession develops.
