Answer:
Yes, a fire takes food for energy.
No, a fire doesn't reproduce.
Yes, a fire produces waste.
Explanation:
For fire, the food that it requires is the objects that help in the process of burning. The objects can be wood, paper, coal, fuel, etc. Oxygen is required for the process of burning to take place.
The process of reproduction undergoes in living beings. Fire produces heat and light but this cannot be termed to be a process of reproduction.
Burning produces wastes in the form of ash and burned products. Therefore, it can be said that fire produces wastes.
A small number of birds arrive on an island from a neighboring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighboring island arrive. What effect do these new arrivals have
Answer:
The environmental variation
Explanation:
Environmental variation has a big role for their beaks to change in a size and shape , that means if the birds like the condition of the place specially birds like to eat cactus fruits that is the reason for their beak rapid change

Q2. A student places peaches into a pure water solution
Give two differences you would expect to find in the water
after ino hours.
Answer:
The correct answer - peaches will swell.
Explanation:
In the hypotonic solution, solution has a higher water potential than that of the cell of peach, so water will move from a region of higher water potential to a lower water potential across via osmosis.
Peaches have more solutes than pure water as it has higher sugar content than pure water. Hence, endosmosis will take place which means the water molecules will move from outside to inside of the peaches through wall of peaches takes place. Due to this, peaches will swell eventually.
Thus, the correct answer - peaches will swell.

Plants that are adapted to live on land ( botanical term)
Answer:
"Embryophytes " is the perfect solution.
Explanation:
Each of some kind of plant sub-system that maintains the embryo inside the maternal tissues, including the tracheophytes as well as bryophytes.The other most common species of organisms or plants seem to be the surface plants including embryophytes, furthermore precisely Embryophyta or Metaphyta. They are considered as 'land plants' but even though, in comparison to the connected green algae, those who continue living primarily throughout terrestrial environments, mainly aquatic ones.Why might the carrying capacity for humans in the United States change if Americans ate more plant products than animal products? Feeding higher on the food chain would make more energy available for humans to assimilate. Consuming plant products would provide less energy because they are generally less digestible than meat. Eating producers would make available about 10 times more energy than eating primary consumers. A diet made up of more plant and fewer animal products would decrease the amount of energy available in food sources.
Answer:
The correct option is:Food producers would make approximately 10 times more energy available than primary consumers.
Explanation:
Diets based on sugars, carbohydrates, fibers, proteins and vegetable fats (that is, with the increased consumption of fruits and vegetables) have much less complex structures than the protein in meat, so much more energy is obtained and easier and faster than vegetables.
A clear example is that carbohydrates have a digestion that lasts between half an hour and an hour, while meat takes at least an hour and a half to digest.
Meats are complex protein structures with primary, secondary and tertiary junctions that must be digested and corrupted with gastrointestinal enzymes, whereas the carbohydrate carbohydrates of fruits and vegetables already begin their digestion in the human mouth thanks to alpha amylase.
The faster the digestion, the faster the energy is assimilated in the form of glucose, and the energy currency that is ATP is greater in diets rich in carbohydrates like the one we are writing, based on fruits and vegetables.
How do the frequencies of the waves compare?
O Wave A has a lower frequency because it has a
smaller amplitude.
O Wave A has a higher frequency because it has a
shorter wavelength.
The waves have the same frequency because they
have the same wavelength.
O The waves have the same frequency because they
have the same amplitude.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
Answer: B.
Explanation: Wave A has a lower frequency because it has a longer wavelength.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a higher occurrence of the full body plate trait, in the lake or the ocean? Explain your answer.
Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.
hope it helps you..
The place where there would be a higher occurrence of the full body plate trait would be:
In the ocean
Based on the given question, we can see that when the ecological divergence which helps the full body plate type to have a higher occurrence in the lake because there is a need for attention.
With this in mind, we can see that in the ocean, there is the higher chance for the full body plate because of the absence of predators and the abundance of resources in the ocean.

Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.

What will most likely increase if there is a high death rate? immigration emigration birth rate population
Answer:
Emigration
Explanation:
If there is a large number of deaths, then the population would move onto another area to find a mate, more food, and to be together to protect themselves from danger
The component of population that will most likely increase with a high death rate would be emigration.
When the death rate shoots up in a particular environment due to certain factors, organisms are bound to emigrate away from such environment to avoid death from reaching them.
It is a natural instinct of every living organism to respond to stimuli. A high death rate is a stimulus that organisms would want to move away from.
