Answer: as the predator’s population goes up, the preys will go down, and as the prey’s goes up, the predators will go up. They are basically the opposite of each other.
Explanation: I can’t really tell what your question is. However if there are more prey to eat, then the number of predators will grow because they have more food. However, once there’s too many predators, the number of prey will drop which lowers the amount of food.
Knowing the food chain works and how predators are opposite to producers there will be that they are indirectly proportional the more producers you have means you have fewer predators and vice versa.
How does the predator-prey relationship happen?Predaism or predation is a disharmonious interspecific ecological relationship, that is, an ecological relationship in which only one species is benefited. In this type of interaction, individuals of one species (predators) kill and feed on individuals of another species (prey).
The organism that kills and feeds on the other is called a predator, and the organism that serves as food is called a prey. Both prey and predator present adaptations related to this interaction.

Al cruzar una ´planta de arveja de flores purpura con otra de flores blancas mendel obtuvo una f1 formada por las plantas de flores purpuras. La f2 estaba formada por plantas
Answer:
F2:
-75% plantas con flores púrpuras
- 25% plantas con flores blancas
Explanation:
La F1 de un cruzamiento entre líneas puras para un rasgo dominante monogénico (en este caso, color de la flor) es siempre igual al fenotipo para el carácter dominante (en este caso, plantas con flores púrpuras). En este ejemplo, el alelo dominante que codifica para el color púrpura enmascara la expresión del alelo recesivo (flores blancas) en plantas F1 heterocigotas. Por otra parte, el cruzamiento entre plantas F1 con genotipo heterocigoto producirá una F2 con una proporción fenotípica 3:1 (es decir, 3 plantas con fenotipo dominante por cada planta con fenotipo recesivo), lo cual es igual a un 75% de plantas con fenotipo dominante (tres plantas: una con genotipo homocigota dominante y 2 con genotipo heterocigoto) y un 25% de plantas con fenotipo recesivo (una planta con genotipo homocigota recesivo). Esto sucede porque los alelos dominante y recesivo responsables del color de la flor segregan independientemente durante la formación de los gametos en plantas F1 heterocigotas.

1.Examine the combined population graph.What population patters do you notice?
2.How does graphing two sets of data on one graph help you see patters in the populations.
3.Why fo you think the changes in the lynx populations so closely follow changes in the hare population?
1. There is a clear correlation between the hare population and the lynx population across time. In particular, we see a correlation between the population sizes: An increase in the hare population is coupled with an increase in the lynx population, and vice versa. The time series population curves match one another in frequency but not in phase: The lynx population shows a slight lag compared to the hare population. The graph shows a cyclical fluctuation in the population. Finally, while perhaps a trivial observation, we see (and could have noted from the data table) that at no point in time is either the hare or lynx population zero. This is rather logical: As long as there are some members of a population alive, the population has the possibility of rebounding; if a population were to be completely extinguished (i.e., the population curve touches the horizonal axis), there would be such possibility, and we wouldn't see the sort of oscillation that we do.
2. A time series visualization of changes in two data sets allows one to track, analyze, and interpret relationships between the elements of the sets both individually and collectively. By graphing two sets of data on one graph, not only can one readily quantify the absolute differences between data from each set at a common point, but one can discern how the data change relative to each other across time. When the data sets are populations of predator and prey species, plotting both on a single time series graph allows one to quantify the populations of each at any given time as well as to compare the rate and magnitude of the changes in the absolute values of the each population within a common interval. Analyzing these parameters can help one discern any correlations between the population data, including (and perhaps most importantly) correlations that are characteristic of predator-prey relationships.
3. Lynx are specialist predators: Their primary prey is the hare. In other words, the lynx population subsists on the hare population. It's not surprising, then, that the number of lynx would be coupled with the number of hare. The greater the hare population, the greater the food supply for the lynx population. When hare are plentiful, the lynx can feed and reproduce: This results in a rise in the lynx population, which eventually results in a fall of hare population due to predation. In turn, the hare population is no longer sufficient to sustain the lynx population, so the lynx population then falls due to starvation. As the lynx population decreases, predation of the hare population also decreases; the lack of predation allows the hare population to reproduce and rise, which in turn replenishes the food supply for the lynx. This is a classic predator-prey population dynamic, and it bears out the correlation between the changes in the hare and lynx populations. Of course, in reality, there are many other factors that affect their population sizes; that's why there isn't a perfectly injective (one-to-one) correspondence in the oscillation between hare population decline and lynx population growth. But the predator-prey interaction here is significant enough to generate the sort of close coupling we see in the changes of their respective populations.

Some fruit flies have orange eyes and others have red eyes. If two orange-eyed fruit flies are crossed, their offspring always have orange eyes. If two red-eyed fruit flies are crossed, their offspring sometimes include both orange-eyed and red-eyed flies. What can be concluded from these observations
Answer:
Orange is a dominant color but red can sometimes be displayed, If two red are crossed and they dont get red then orange is dominant and displayed earlier in the gene pool
Explanation:

a. What is likely to happen to coral reefs if atmospheric carbon dioxide
concentrations continue to rise? What will be the consequences for the biosphere?
Answer:
Coral reefs are under threat if atmospheric carbon dioxide levels continue to rise, new research has shown. When CO2 dissolves in the ocean, it raises the water's acidity level. This prevents a build up of calcium carbonate, which corals draw from seawater to build their skeleton
Explanation:
If atmospheric carbon dioxide continues to rise it creates a threat condition to coral reefs to their skeletons.
What are coral reefs?According to recent research, coral reefs are in danger if atmospheric carbon dioxide levels keep rising. The ocean's water becomes more acidic as a result of CO₂ dissolving there.
This hinders the buildup of calcium carbonate, which corals use to create their skeleton from saltwater. More CO₂ is absorbed by the seas when CO₂ emissions rise.
The water is getting warmer as a result of increased greenhouse gas emissions. In water that is too much warmer or colder than 26–27 degrees celsius, coral cannot survive.
Therefore, as a result, coral has a tougher time developing its shells since the water becomes more acidic.

Answer:
The clavicles of a chicken are Y-shaped.
Many similarities are noted in the clavicles of a chicken and theropod. Both clavicles are fused to form a single V-shaped structure.
The clavicles of a chicken are Y-shaped.
What is collarbone?One of the primary bones in the shoulder, the collarbone, can break and suffer from a clavicle fracture. About 5% of all adult fractures are of this type, making it a reasonably common fracture.
The majority of clavicle fractures happen when the bone is sufficiently compressed—either by a fall onto the shoulder or an outstretched arm—to snap or break. With a broken collarbone, your arm may be difficult to move and may be quite painful.
Wearing a sling to prevent the arm and shoulder from moving while the bone heals is a common treatment for clavicle fractures. However, in some clavicle fractures, the damage causes the bone fragments to shift drastically out of position.
Therefore, The clavicles of a chicken are Y-shaped.
