Which object is hotter in terms of its kinetic energy: the cup of coffee or the iceberg? Explain the reason for your answer in terms of your understanding of the kinetic molecular theory of matter.
Answer:
red-hot iron bar
Explanation:
An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

Answer:
i think that the higher the body temperature the higher the cellular respiration
Explanation:
The graph indicates the relationship between body temperature and cellular respiration. As the body temperature increases, more ATP is produced, but after a certain temperature, there is no cellular respiration.
What is cellular respiration?In cellular respiration, the cell breaks down glucose and forms ATP. Glucose is broken down by glycolysis, the Krebs cycle, the electron transport chain, and finally ATP is formed.
In the graph, it is shown that an increase in body temperature is related to an increase in ATP molecule production. ATP molecule production is nearly zero at 80 degrees body temperature. As the temperature increases to 100 degrees, ATP production increases to nearly 50.
After 100 degrees, the body temperature rises, but there is a decrease in ATP production. After 100 degrees, the enzymes required for cellular respiration don't work. Hence, a decline in ATP is seen.
Hence, after a certain temperature, the enzymes involved in cellular respiration don't function as their structure changes.

the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:
Height×Width×number of sides and number of boxes
Surface= area of volume ratio is calculated with an equation
Area /volume
if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.

o choose the most effective method to eliminate pests
O use natural rather than synthetic methods to control pests
choose the safest approach with the least human risk
o do the least possible harm while controlling pests
this is for my plant systems class
Answer:
Use natural rather than synthetic methods to control pests.
Explanation:
Integrated Pest Management (IPM) encompasses a variety of techniques used to maintain an acceptable level of pests in a given environment. that limits use of pesticides and maintains soil nutrients for future crops. Its four components are prevention, avoidance, monitoring, and suppression.These practices rely on natural efforts first
Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer
Answer:
A - Gain or Lose
Explanation:
Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.
During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.
The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.
For covalent bonding atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
Answer:
Explanation:A: gain or lose

Answer:
What is Fungus (mushroom)
Explanation:
The living body of the fungus is a mycelium made out of a web of tiny filaments called hyphae. The mycelium is usually hidden in the soil, in wood, or another food source. A mycelium may fill a single ant, or cover many acres.
Air,water and soil may well be a place living things exist in, ecosystem, but they are in no way living.

Fungus (mushroom) is the living thing in environment. Thus option C is correct.
What are the types of environment ?The surrounding of living organism including both the biotic and abiotic factors called as environment. It may be natural, social, or built environment.
Majority of the environment is composed up atmosphere, hydrosphere, lithosphere, and biosphere.
It can be up microenvironments which is the immediate local surroundings of an organism and secondly macro environments refers to biotic and abiotic factors.
Two common types of environment such as natural or geographical environment, and man-made environment.
Geographical environment include terrestrial environment independent of humankind. For example rivers, deserts, water, oceans.
Man-made environment refers to a social environment. It is completely dependent on human social influence.
For example, city infrastructures, houses, transport and communication etc.
Thus option C is correct.

Fertilizers are the chemical element for improvement of productivity of plants. Here, 0-15-15 shows nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.
Why to label fertilizer?Labeling of fertilizer is to show the content of major nutrients. They are usually labeled with three numbers i.e., N-P-K label, i.e., Nitrogen-Phosphorous-potassium label , such as, 0-15-15. the first number is the percentage of nitrogen, second is for phosphorus and third is for potassium.
Thus, here as per the marking, the quantity of the nutrients are: nitrogen 70 pounds, phosphorous 15 pounds and potassium 15 pounds.

Explanation:
While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For this question, identify the seemingly primitive traits and discuss how their presence in both Platyrrhines and Prosimians may reflect an example of convergent (parallel) evolution. (150-250 wds)
Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.
The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:
Teeth layoutDietEyesight Sleeping habitsand more.
The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.
Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.

A. Large amounts of water force open cracks in rocks
B. Removal of topsoil to reach water supply
C. Transportation of coal via waterways
D. Use of machinery underground to mine coal
Answer:
A. Large amounts of water force open cracks in rocks
Explanation:
Hydraulic fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the Earth. In the fracking process, cracks in and below the Earth's surface are opened and widened by injecting water, chemicals, and sand at high pressure.
A is basically explaining this the same way. Forcing cracks in the ground with liquids.
