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.

D.
No, because the cooler seeds sprouted sooner.

Answers

Answer:

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.

Which of the following are true statements regarding cellular respiration? Lactic acid fermentation is an aerobic process The final electron acceptor in the electron transport chain is oxygen ATP are produced in Krebs cycle Two of these answer choices are correct All of these statements are correct

Answers

Answer:

not all of the statement is correct. THE LACTIC ACID FERMENTATION IS ANAEROBIC not an aerobic.

The statements which are correct regarding cellular respiration are;

The final electron acceptor in the electron transport chain is oxygen.ATP are produced in Krebs cycle.

As such, Two of the answer choices are correct.

Lactic acid fermentation is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.

The electron transport chain is one of the series of catabolic pathways of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism.

The Krebs cycle takes place in the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). ... It is at this stage that NADH is converted into ATP.

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?
Part 2
What type of heat transfer is demonstrated in Part 2?
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?

Answers

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

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".

Answers

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.
