A controlled experiment was conducted to analyze the effects of darkness and boiling on the photosynthetic rate of incubated chloroplast suspensions. The dye reduction technique was used. Each chloroplast suspension was mixed with DPIP, an electron acceptor that changes from blue to clear when it is reduced. Each sample was placed individually in a spectrophotometer and the percent transmittance was recorded. The three samples used were prepared as follows.
Sample 1 – chloroplast suspension + DPIP
Sample 2 – chloroplast suspension surrounded by foil wrap to provide a dark environment + DPIP
Sample 3 – chloroplast suspension that has been boiled + DPIP
On the axes provided, construct and label a graph showing the results for the three samples.

Answer:

x and y

Explanation:

x and y have the smallest orbital radius so they are likely to be inner planets while w and z have bigger orbital radius so the probability of them being inner planets is low.

Complete question:

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?

Answer:

Explanation:

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,

In 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.

Answer:

By looking at all the age population pyramids, this would be my best guess. Every territory is different with various populations, however, to the best of my knowledge, it would be the expansive pyramid. Expansive population pyramids are used to describe populations that are young and growing.

Answer:

They would freeze and it would be hard to find food because they are not accustomed to the different climate. They would also be easy prey because of the environment change they are not equipped for.

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.

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.

Answer:

What's the question

Explanation:

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 :)

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.
