Answer:
The correct answer is -
8. They played the songs of medium ground finches and cactus finches through a loudspeaker at different times, when individuals from both species were present, to see which species responded to each song.
9. Males only came to the loudspeaker when the song of their own species was being played.
Explanation:
To test the hypothesis that differences in finches song they sing keep these finches to breeding from other members of finches, Grant should play the different songs of both medium ground finches and cactus finches one by one in loudspeaker and see what members of finches respond on what song.
It will show that cactus fiches breed only on their songs and medium ground finches on their song if the hypothesis is true. Male of each species respond to their songs only and not on other song played on loudspeaker
A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population’s ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Delayed density dependence Delayed density independence Extinction vortex Carrying capacityAnswer:
Delayed density dependenceExplanation:
The Delayed density dependence occurs when two species are in interaction (prey-predator or parasite-host), and the dynamic of each population follows the dynamic of the other population. The natality and mortality rates of one species follow the rates of the other species.
Delayed density dependence dynamics regulate populations and allow the occurrence of equilibrium or balance in nature.
Predator-prey scenarios
Assuming that the prey lives in the ideal environment with no predators, it shows an exponential growth rate. Prey can grow, develop, and reproduce, increasing its population size. The more available items, the more predator there will be. The predator population increase in size, and its presence affects the prey populations, leading it to decrease. So there are fewer available items to prey on.
The prey population also affects the predator population. After the increase in the predator population size, the number of available prey decreases. The predator lives in an ideal environment but depends on the prey density. The more predators there are, the fewer prey there will be left. The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.
So, to sum up,
prey population increases in sizepredator population increases in sizeprey population decreases in sizepredator population decreases in sizeIn this particular example, the wolves population follows the moose population and vice-versa. It is not simultaneous. It happens with a delay.
Moose influences the wolf population because they are their source of food. The more moose, the more wolves there are. The fewer moose, the fewer wolves there are.
This is a density-dependent dynamic because both populations are affected when they reach a high value.

The overall efficiency of oxidative phosphorylation, assuming standard conditions, can be calculated by comparing the free energy potentially available from the oxidation of NADH by O2 to the free energy required to synthesize 2.5 ATP from 2.5 ADP. This comparison reveals an efficiency of 35%, which is based on the experimental measurement of 2.5 ATP for every NADH oxidized during oxidative phosphorylation. Using this efficiency, calculate the number of ATP generated by each of the following Complexes:
Answer:
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.
Explanation:
It is known that at the end of Kreb's cycle 10 NADH are produced
Now by using the unitary method
1 NADH produces=2.5 ATP
10 NADH produces=2.5 ATP x 10
10 NADH produces=25 ATP
This is for the efficiency of 35%.
35% efficiency produces ATPS=25
1% efficiency produced ATP=[tex]\dfrac{25}{35}[/tex]
100% efficiency produced ATP=[tex]\dfrac{25}{35}\times 100[/tex]
100% efficiency produced ATP=71.42 ATP
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.
What are some featured species in the deep sea?
What is so fascinating about our deep blue sea is the fact that there could be so many more species than the ones we know about. Our oceans are so vast and deep anything could really be down there. I don't exactly know what you mean by this question but I can give you some deep-sea creatures that have been discovered, although some sound equivalent to science fiction, they are in fact real.
- Giant Isopod: they are a species of aquatic crustacean. Their appearance is that of a much larger bug, similar to those "rolly polly" bugs. They reside in the deep sea scuttling along the seabed and ultimately harmless to humans.
- Vampire Squid: This creature looks similar to many other squids such as their squid-like bodies and tentacles, however, what makes this squid unique is its black webbed skin (resembling a vampire cape) and its red eyes. The vampire squid's body is covered in photophores that produce light to attract prey.
- Frilled Shark: This is an odd-looking shark that lurks in the deep sea. It looks almost pre-historic and can grow up to a length of 7ft with a typical shark fin further down its back as well as the well-known rows of sharp teeth. Its gills appear to be frilled hence its name.
- Anglerfish: These deep-sea creatures are pretty commonly known. They are frightening-looking fish with long thin teeth lining their mouth and the notable luminescent fin ray that it uses to lure other fish to eat.
So these were just some notable deep-sea creatures that I have heard of and I wrote some information about them. Hope this helped :)

What does it mean when organisms are in the same horizontal line
in a cladogram
Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. A cladogram can be simple, comparing only two or three groups of organisms, or it can be enormously complex and contain all the known forms of life.
Cladogram design is universal, although simple. A cladogram consists of the organisms being studied, lines, and nodes where those lines cross. The lines represent evolutionary time, or a series of organisms that lead to the population it connects to. Nodes represent common ancestors between species. At some point in the past a population of common ancestor organisms was divided, giving rise to the different organisms being studied. Some cladograms show evolutionary time through the scale of the lines, longer lines meaning more time. Some cladograms chose to show extinct species, while others omit them. Any particular cladogram is formulated specifically for the use it is needed.

g The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. it rises to the surface and absorbs wavelengths needed by aquatic plants it causes the water to become murky it decomposes endothermically causing the temperature of the water to decrease below the limits within which most aquatic organisms can live it causes oxygen depletion in the water it causes death of bottom dwelling organisms because it agglutinates and settles to the bottom, poisoning bottom dwelling organisms
Answer:
It causes oxygen depletion in the water
Explanation:
When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.
Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.
Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.
Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.
When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.

Describe what happened to the colored water and the pieces of paper after the holes were punched in the material covering the beaker
Answer:
The paper spreads over the surface of water and the colored water sunk to the bottom.
Explanation:
The paper hole punches were spread over the surface of the water in the large beaker due to lower density of paper as compared to water whereas the colored water had sunk to the bottom. Convection currents is the driving force that caused the pieces of paper to move over the water's surface. At the surface, the water cools and becomes more denser so the coloring sank toward the bottom of the beaker creating convection currents that will leads to the presence of paper on the surface of water.
