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.

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.

Which of the following emotions is the last to develop in an infant?
Select one:
a. pride
b. fear of strangers
c. anger
d. curiosity
Pride is the last emotion to develop in an infant. So the correct option is A.
When do emotions develop in an infant?
From the moment of birth, babies are able to convey their curiosity, pain, disgust, and enjoyment through their body language and facial expressions. Around 2 to 3 months old, babies start smiling spontaneously, and around 4 months old, they start laughing. Infants also display other emotions, such as anger, sadness, surprise, and fear, between the ages of 2 and 6 months. Babies start to show signs of stranger fear between the ages of 5 and 6 months.
They will express their displeasure openly when someone holds or plays with them since they do not enjoy it. They used to grin at everyone and let people hold them. Babies are nevertheless learning at this time how to recognize the sentiments of others as well as how to express their own. Infants can start recognizing the various emotional emotions of others at the age of 4 months. Babies don't start mimicking emotions and facial expressions until they are approximately 6 months old.
Babies generally treat their caretakers interchangeably at birth because they lack the ability to recognize individual differences. They do, however, start to develop a strong attachment or relationship with their primary caretakers as the months of their first-year pass and their perceptual and processing capacities advance.
Therefore, the correct option is A.

This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others
The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.
In the ecosystem, the living and non-living things interact over time leading to exchange of energy.
A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.
The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).
The energy flow is indicated with an arrow thus,
grass ---> rabbit -----> wolves.
Food chain, therefore includes linear sequence of organisms.
Food web on the other hand illustrates a complex feeding relationship within the ecosystem.
The food web is made up of a prey that can be eaten by more than one predator.
Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Generalized global air circulation and precipitation patterns are caused by ________.
A. solar radiation that warms moist air masses near the equator, which then cool and release precipitation as they rise, and then, at high altitude, move north or south of the tropics and sink back to the surface as dry air masses
B. air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas
C. polar, cool, moist, high-pressure air masses from the poles that move along the surface, releasing precipitation along the way to the equator, where they are heated and dried
D. solar radiation that warms dry air masses at the poles, causing them to sink toward the tropics, gain moisture, and then release it as precipitation.
Answer:
option B is the right answer
Generalized global air circulation and precipitation patterns are caused by air masses that are dried and heated over continental areas, which then rise, cool aloft, and descend over oceanic areas, followed by a return flow of moist air from ocean to land, delivering high amounts of precipitation to coastal areas. The correct option is B.
What is differential heating?The reason we have different weather patterns, jet streams, deserts, and prevailing winds is due to global atmospheric circulation caused by the rotation of the Earth and the amount of heat received by different parts of the globe.
The earth's polar regions are both cold, owing to the fact that they receive far less solar radiation than the tropics and mid-latitudes.
Air masses that are dried and heated over continental areas cause generalized global air circulation and precipitation patterns.
This is then rise, cool aloft, as well as descend over oceanic areas, accompanied by a return flow of humid air from ocean to land, achieving higher amounts of precipitation to coastal areas.
Thus, the correct option is B.

Answer:auditory tube
Explanation
The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
What is the structure of Ear?The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.
Types of bones present in the ear are
1. Hammer shaped bone known as malleus which is attached to the eardrum.
2. Anvil shaped bone known as incus present in the middle of the chain of bones.
3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).
The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.
A: 90
B: 10
C: 100
D: 45
Answer: A
Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.

Associate specific relationships between science and/or technology and human population growth.
The relationship between population growth and technological change has been debated since the end of the eighteenth century a debate whose main configuration has proved remarkably persistent. During the ensuing 200 years, historically unprecedented rates of change have been observed in both variables: in industrial, commercial, and communications revolutions spreading out from Europe, North America, and Japan; in parallel (though spatially and temporally uneven) revolutions in the technological base of agricultural production; and in a demographic transition–in which mortality decreased and fertility first increased, then decreased that is still underway in many developing countries. Interconnections there must be, yet the attribution of primacy and direction of causation among these variables, not to mention the nature of the mechanisms involved and means of influencing outcomes in the interest of meeting social goals, remain controversial. Meanwhile, a new awareness of the emergence of complex social-environmental systems, whether at local or global levels, has extended the debate beyond the discipline of economics, and broadened its emphasis from the welfare of the human race to that of the planet.
