You close your eyes, with your hand in front of your face for one minute. You quickly blink your eyes and find that even with your eyes closed, you can "see" your hand briefly. Why does this occur?
1) because elaborative rehearsal has transferred this image to your Long-Term Store/Memory, where it is stored indefinitely
2) because auditory images are held in Sensory Store/Memory for up to several seconds
3) because visual images are held in Sensory Store/Memory for up to about 1/4 second
4) because maintenance rehearsal keeps this image in your Short-Term Store/Memory indefinitely
Answer:
because visual images are held in sensory store/memory for up to 1/4 second
You can "see" your hand briefly because visual images are held in Sensory
Store/Memory for up to about 1/4 second.
When the sensory organ involving the eyes views an object briefly, the
information is usually passed to the brain which tells the type of object and
the action to take in response to the stimuli.
In this case, the visual image are usually held in the sensory
store/memory(brain) for few seconds which is why it is seen briefly even
after closing the eyes.

Explanation:
What evidence do the positions of the peaks and dips in its spectrum provide about an object? A. expansion B. elemental composition C. motion D. temperature
Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.
The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.
These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.
When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that less light is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, the peaks tell you what kinds of bonds are present from which we can identify the elemental composition.

How does the Earth get its brand new NITROGEN?
Answer:
Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

Answer:
A system that uses the sun's energy without requiring mechanical devices (pumps or fans) to distribute the collected heat are called solar system while radiator system uses fuel to heat the water. in active solar heating system, the SUN's energy used to heat water.
The comparison of an active solar heating system with a radiator system gives; Solar systems use the sun's energy to heat water without the need for mechanical equipment to disperse the heat, where radiator systems require fuel to heat the water.
What is an active solar heating system?Active solar heating systems employ solar energy to heat a fluid (liquid or air), which is then transferred to the interior area or stored for later use.
In conclusion, an active solar heating system and a radiator system are all subs of heat energy

Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.

What would happen to the DNA molecule if the pairing was non-complementary, in other words, the two purines (adenine and guanine) paired with one another and likewise the two pyrimidines (thymine and cytosine) paired with each other.
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.
