Select the correct answer from each drop-down menu. when a cat drops from a tree to the ground, the conversion of takes place. then cat runs up behind a mouse to obtain its food. after eating its prey, the conversion of takes place inside the cat’s body.
The correct answer from each drop-down menu is gravitational force, potential energy to kinetic energy, and then conversion of chemical energy to mechanical energy take place in this order.
What are the forms of energy conservation?During the energy transformation steps, when there is no frictional dissipation, we say that energy is conserved. That is, all potential energy is transformed into kinetic energy, and vice versa. The sum of the kinetic and potential energies of a system is called mechanics.
In this case, When a cat drops from a tree to the ground follows the gravitational force, while the conversion of up behind a mouse to obtain its food is the process of converting potential energy to kinetic energy. And at last, after eating its prey, the conversion inside the cat's body takes place the chemical energy to mechanical energy.

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.

which type of drosophila probably changed the least over time?
The type of Drosophila that probably changed the least over time is the Drosophila melanogaster.
What do you mean by Drosophila?A Drosophila may be defined as a fruit fly that serves as one of the most important model organisms in the field of biological sciences due to its large chromosomes, high reproduction rate, and various varieties.
As compared to Drosophila willistoni, Drosophila equinoxialis, Drosophila equinoxialis caribbensis, etc. Drosophila melanogaster changed very least over time after analyzing its evolutionary pathway.
It is because it may consist of a large chromosome but a simple arrangement of genes, its well-specified segment polarity genes, pair-rule genes, and maternal effect genes.
Apart from this, it may also be because of less natural selection applied to Drosophila melanogaster.
Therefore, the type of Drosophila that probably changed the least over time is the Drosophila melanogaster.

Which of the two sequences of rocks, a-d and e-g, was disturbed by crustal movements after its deposition?
Answer:
Sequence A-D was disturb by crustal movement after it was deposition. We have evidence in given cross section that sequence A-D was disturb by crystal movement just see above this sequence there is conglomerate bed which indicates it is uncomformity and that below uncomformity plane all beds are inclined so it clear evidence that sequence A-D got disturbance by crustal movement.
Explanation:
Sequence order and principal are given below.
one can order the event in any given cross section on the basis of apply some principal like order of super position, principal of cross cutting relationship, principal of inclusion, principal of original horizontality etc. Order of superposition tell us that if rock is undeformed then older rock would be at bottom and younger at top, principal of cross cutting relationship tell if some igneous body intruded in some rock layer so it mean that layer is older than age of intrusion.

Excretion and the Kidneys The kidneys remove excess water, minerals, and other waste products from the blood. The cleansed blood returns to circulation. Each kidney has nearly a million processing units called nephrons. Filtration and reabsorption occur in the nephrons.
- Filtration is the passage of a fluid or gas through a filter to remove wastes. The filtration of blood in the nephron takes place in the glomerulus, a small, dense network of capillaries. Each glomerulus is encased by a cuplike structure called Bowman's capsule. Pressure in the capillaries forces fluids and wastes from the blood into Bowman's capsule. This fluid is called filtrate.
- Most of the material that enters Bowman's capsule is returned to circulation. The process by which water and dissolved substances are taken back into the blood is called reabsorption.
- A section of the nephron tubule, called the loop of Henle, conserves water and minimizes the volume of filtrate. The fluid that remains in the tubule is called urine.
For Questions 7-10, write True if the statement is true. If the statement is false, change the underlined word or words to make the statement true.

The nephrons paintings via a two-step procedure: the glomerulus filters your blood, and the tubule returns wanted materials for your blood and eliminates wastes.
