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​

Answers

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.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP

Answers

Answer:

B

Explanation:

The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2

the answer is not exact, but it is the closest to the actual equation

The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.

What is photosynthesis?

Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.

The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.

Thus, option B is the correct option.

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

Answers

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.

describe evidence from biogeography that species evolve adaptations to their environment

Answers

Answer:

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

The published data for the map distance between the gene and the centromere is 26 map units. You just calculated the map distance as 17 map units. What is the best explanation for this disparity

Answers

Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.

A linkage map is based on the frequency of recombination events between genes or molecular markers.

This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.

Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

But we do know that linear momentum (p) is mass(m)× velocity (v)

P=m×v

V=p/m

Substituting the value here we get,

V= 10/100

As the pot is heated, the temperature inside increases until the water starts to boil. ... At that pressure, water boils at 121°C (250°F). That means food can cook at a much higher temperature than it ever could at atmospheric pressure—and since cooking reactions speed up at higher temperatures, your food cooks faster.
