Briefly explain how energy is transferred from organism to organism in the food web.
Answer:
energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from it's prey body.
Explanation:
however these transfers are inefficient,and this inefficiency limits the length of food chains

DNA ligate play an essential role in maintaining genomic integrity by joining breaks in the phosphodiesterase backbone of DNA that occur during replication and recombination, and as a consequence of DNA damage and its repair.
Why do efforts to prevent all fires from occurring in forests actually tend to make these ecosystems more vulnerable to fire?
Answer:
they feed off of the efforts to control the fires on forests
Explanation:
they cause heat trapping for wildfires to grow. These patterns occurred in 1880 as a result, led multiple forest fires that were hard to control and over time increased chances of happening again.

Question is specific and clearly
connects the relationship
between carbon dioxide (CO)
and temperature
Answer:
The Temperature rises as carbon dioxide levels rise. The temperature decreases when the carbon dioxide concentration falls.
Explanation:
A tiny part of the correlation is attributable to the relationship between temperature and carbon dioxide solubility in the surface of the ocean, but most of it is consistent with feedback from carbon dioxide to the environment. These changes are expected to be consistent with Earth's radiative balances and the function of greenhouse gases in climate change. While determining the cause and impact, initially or by some other method, between carbon dioxide and climate, may appear straightforward, it still is extremely difficult to find the cause and effect. Other changes include altered vegetation, earth surface properties, and ice-sheet extent in the glacial climate.
Other paleoclimate representatives allow us to comprehend the role of the oceans in climate change in the past and future. The ocean holds 60 times as much carbon as the atmosphere, and the change in carbon dioxide in the atmosphere is predicted throughout the past several hundred thousand years to be compared to carbon changes in the ocean. While oceans vary far more slowly than the atmosphere, in past CO2 fluctuations the ocean has played a key role and will play a part for millennia in the future.
Finally, paleoclimate data demonstrate that there is not only temperature about climate change. In the past, many other aspects of the climate have altered as carbon dioxide has changed. The snow was lower, the continents dried and the tropical mousses weaker during the glacial ages. Some of these changes may be independent; others may be closely associated with changing carbon dioxide levels. A thoroughness of research is to understand what these changes might occur in the future and how substantial these changes may be.. The Paleoclimatology Program of the NOAA provides scientists with a documentation of previous changes as an approach to understanding future climate change.
why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?
Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
In which of the following organisms did photosynthesis most likely first
evolve?
A. Algae
B. Prokaryotes
C. Plants
D. C4 plants
The following organisms did photosynthesis most likely first evolve - B. Prokaryotes
Sufficient evidence indicates that eukaryotic photosynthesis originated from endosymbiosis of cyanobacterial-like organisms
ultimately these prokaryotes became chloroplasts in eukaryotic cells.So the evolutionary origin of photosynthesis is to be found in the bacterial domain.The geological record indicates that this transforming event took place early in Earth's history, at least 2450–2320 million years agoThus, The following organisms did photosynthesis most likely first evolve - B. Prokaryotes

Scientists compare the structures of a chicken embryo and a human embryo at the same stage of development. They find that both vertebrates have similar shapes and structures, including the presence of gill slits and tails. How is this comparison of the embryos used as supporting evidence of evolution?
A. The similarities suggest that chickens and humans are the direct descendants of modern-day fish with tails and gill slits.
B. The similarities suggest that vertebrates pass through each of the adult stages of their evolutionary history as they develop.
C. The similarities suggest that vertebrates can undergo genetic changes during development that lead to the evolution of new species.
D. The similarities suggest that chickens and humans descend from ancestors with genes that code for the development of tails and gill slits.

Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.
Natural selection inhibited the eggs from hatching before expected because this trait is negative in terms of survival and reproduction.
How does natural selection work?Natural selection is a natural process that causes evolution over time. This mechanism implies only individuals with traits that represent an advantage for survival and reproduction will prevail over time, which causes the traits of these individuals to become dominant.
For example, if in a population of deer male deer with big antlers are more likely to survive and reproduce, it is expected after some generations this trait is dominant.
How does natural selection work in the red-eyed tree frog case?In this situation, we know that if an egg hatches before time the embryo is not likely to survive. This means this trait is a disadvantage in terms of survival and reproduction, and due to this and as a result of natural selection the trait is not dominant.

The death rate is becoming lower than the birth rate
The death rate is constant and the birth rate is increasing
The death rate is becoming higher than the birth rate
Answer:
The death rate is becoming higher than the birth rate.
Explanation:
Birth rate means the population increases, and death means decreases.
Answer:
The death rate becoming higher than the birth rate
Explanation:
if the death rate is becoming higher and the birth rate is getting lower then the population will die off and the birth rate would decress.
