A student redid the experiment of mixing room-temperature water and warm
water. This time, she doubled the amount of warm water. How will the final
temperature be different?
A. It will be higher, because the amount of water in the mixture is
greater
B. It will be the same, because all parts of the mixture will end up at
the same temperature.
C. It will be lower, because the room-temperature water will absorb
more thermal energy from the warm water.
D. It will be higher, because the warm water will transfer more
thermal energy to the room-temperature water.
The final temperature will be different by having a high temperature because the warm water will transfer more thermal energy to the room-temperature water. Thus, the correct option is D.
What is Temperature?The Temperature may be defined as the degree of hotness or coldness measured on a definite scale at a particular location.
If we mix room-temperature water with warm water, the temperature of mixed water is found to be high as compared to the previous room water temperature. This is because warm water is capable of transferring its thermal energy to room-temperature water.
Therefore, the correct option for this question is D.

Answer:
glucose
Explanation:
C6H12O2 has you can see there is O2 in the expression. which is oxygen.
Which describes the process of photosynthesis?
A carbon dioxide + water → glucose + oxygen
B glucose + oxygen carbon dioxide + water
C water + oxygen → glucose + carbon dioxide
D glucose + carbon dioxide - water + oxygen
please explain:)
Answer:
a
Explanation:
basically to remember this, plants take in carbon and release oxygen; the opposite as humans. and for the second part water is needed to produce glucose. the formal definition is "glucose is made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, which is the most abundant carbohydrate." im sorry if this isnt best explanation but i wanted to make sure someone answered your question
Which phase change process below involves the addition of thermal energy or heat? (select all of the ones that apply)
1. sublimation
2. melting
3. freezing
4. vaporization
5. condensation
Answer:
Melting and Vaporization are processes among the following which involves the addition of thermal energy or heat.
The phase change process below involves the addition of thermal energy or heat melting and vaporization are processes among the following which involves the addition of thermal energy or heat. Thus, option D is correct.
What is vaporization?The term vaporization has been described as the vaporization has the change of phase from liquid state to gas state and condensation is the change of phase from gas state to liquid state. Freezing has the process in which phase change or state change takes place it means that a process in which a liquid change into solid.
Freezing process can be achieved by extracting heat i.e or removing latent heat, latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without change in temperature.
So, during the formation of ice from water, heat is removed from water at zero degree Celsius at constant temperature, then water changes into ice and a freezing or solidification process may occur in a liquid, initially at a uniform temperature, either above or at the the freezing temperature or fusion point. Freezing is the process which cause ice to form a thin layer over a lake.
Therefore, The phase change process below involves the addition of thermal energy or heat melting and vaporization are processes among the following which involves the addition of thermal energy or heat. Thus, option D is correct.

GCGATT would be the DNA sequence that is equivalent to CGCTAA. Therefore, the correct statement is option D.
What are complementary base pairing rules?Adenine (A) and thymine (T) are the complementary base pairs in DNA, while cytosine (C) and guanine (G) are the opposites. Therefore, the complementary sequence for the given sequence would be GCGATT (complementary) paired with CGCTAA (original) on the opposite strand.
GCGATT would be the complementary code on the opposite strand of the helix. According to the complementary base pairing rules, C (cytosine) pairs with G (guanine) and A (adenine) pairs with T (thymine). On the complementary strand, the original sequence CGCTAA and GCGATT would therefore pair.
During the process of cell division, DNA replication is dependent on this complementary base pairing. The complementary base pairing rules guarantee that the two new DNA strands produced during replication have the same sequence of bases as the first one.
Therefore, GCGATT is the complementary code on the other strand of the helix.

What process is oxygen necessary for in all living cells? What are the different ways 3 organisms get oxygen: flatworm, fern, human?
Answer:
This process is called cellular respiration.
Explanation:
Human- We get oxygen by breathing in fresh air, and we remove carbon dioxide from the body by breathing out stale air.
Flatworm- In order to breathe, they must be able to pass oxygen and carbon dioxide in and out of their bodies through their skin by diffusion. In order for this to work, even the largest flatworms are extremely thin.
Fern- Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide.
