You have learned that heat moves from warm areas to cooler ones. In solids, heat is transferred by the physical touching of molecules. This type of heat transfer is called conduction. Some materials, like metal, conduct heat better than other materials. In fluids (liquids and gases), heat is transferred by convection currents caused by differences in density.
MATERIALS
hot water
cold water
metal fork
plastic fork
stick of cold butter
large glass
watch or clock with a second hand
yellow and blue food coloring
playing card
four empty, identical plastic bottles (sports drink bottles work well)
access to a sink
QUESTIONS
Part 1
What type of heat transfer is demonstrated in Part 1?
How long did it take for the butter to melt off of the plastic fork? The metal fork?
How do explain the difference in time between the two forks?

What happened when the warm water bottle was placed over the cold water bottle? Why?
What happened when the cold water bottle was placed over the warm water bottle? Why?
Pt. 1
In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another. ... If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
Pt. 2
This motion of fluids is called convection. In the set of bottles where the hot water was above the cold water, the cold water was already on the bottom, so there was no convection.
Pt. 3
When the bottle was put into the cold water, the air in the bottle contracted, taking up a smaller space in the bottle. The sides of the bottle pushed in when the air inside controlled

Q.which bird don't make its own nest?
The common cuckoo does not make a nest of its own, and they do not bring up their own young. Instead, the female lays her eggs in the nests of other birds. Each female cuckoo specialises in just one host species, and lays camouflaged eggs in that bird's nest.
when a piece of zucchini is soaked in salt water, the zucchini loses its firmness. Which process best explains what happens to the zucchini?

g Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space. The pH in the mitochondrial matrix is lower than the pH in the intermembrane space. Energy is generated as a result of the difference in hydrogen ion concentration between the intermembrane space and the cytoplasm. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
what force dose dark energy have on the universe?
Juanita and Alfred hypothesize that a seed will sprout faster if it is warmer. They plant three seeds and water them the same amount. One seed is placed near a heater, one is left at room temperature, and one in a refrigerator. The results are shown in the table below. Do the results support the hypothesis?
Temperature of Seed Days to Sprout
by heater 2 days
room temperature 5 days
in refrigerator did not sprout
A.
No, because the seeds all sprouted at the same time.
B.
Yes, because the cooler seeds sprouted sooner.
C.
Yes, because the warmer seeds sprouted sooner.
D.
No, because the cooler seeds sprouted sooner.
Answer:
C
Explanation:
Yes, because the warmer seeds sprouted sooner.
Yes, because the warmer seeds sprouted sooner.
What is Room temperature?
The typical temperature range in a home is widely agreed to be between 68 and 76 degrees Fahrenheit, specific variations and geographic variations aside.
The use of smart home appliances, such as a smart AC controller, automates the maintenance of these typical house temperatures at all times, however keeping the ideal room temperature is a challenge.
The location, season, type of house, and personal preferences are just a few of the many variables that can dramatically affect the appropriate room temperature. When determining appropriate room temperatures, home architecture is a crucial factor.
Therefore, Yes, because the warmer seeds sprouted sooner.

Explanation:
Use a Punnett's squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants.
The tall trait is dominant and thus is represented by the uppercase letter "T". The dwarf trait is recessive and is represented by
to lowercase letter "t".
Answer/Explanation:
True breeding means the parents have two copies of the same allele (two of the same letter)
That means the monohybrid cross is TT x tt
T T
t Tt Tt
t Tt Tt
All the offspring have one copy of each and are Tt. Tall is dominant to dwa rf. So all the offspring will be tall.
