Complete question:
In Australia, both opossums and foxes eat rats. The sizes of the populations have been stable for the last 12 years, but recently the size of the opossum population increased. What will likely happen to the fox population? It will . .
increase. An increase in the size of any population leads to an increase in the size of all other populations in an ecosystem. stay the same. Opossums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same. decrease. The larger opossum population will leave fewer energy storage molecules for all other populations in the ecosystem, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population. decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.Answer:
Decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.
Explanation:
In the trophic web occurs a process of energy transference through different organisms that places at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
In the exposed example, foxes are affected by the increase in the opossum population size, that a direct competitor.
Both species, opossums and foxes, feed on the rats. As long as their population sizes remain stable, no species will be hardly affected by the other. However, when a change occurs, the size of any of the populations is altered, indefectibly affecting the other populations. In this example, the opossum population increased. The more opossums are in the region, the more they will prey on rats. Opossums will become stronger competitors to foxes, whose population remains the same. Rats´ population is also affected because they do not have enough time to reproduce at a higher rate recover. So we have

They do not have enough food to feed on and to survive. And they do not have enough energy to reproduce. So the survival and reproductive rates in the foxes population decrease. And as they do not have enough food, their death rate increases. Eventually, the fox population decreases in size.

7. The diagrams show stages in the passage of water through a plant,
The circles are the starting points for arrows to show the direction in which the water moves.
Which circle must have an arrow pointing downwards only?
From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.
Water moves through a plant in the following direction:
Soil ----> root -----> stem ----> leaves
Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.
Circle D represents the root, so the arrow must be upward.
Circle C represents the stem, the arrow continues upward towards the leaves
Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.

What is adaptation? What are the two types of adaptation? Give an example each.
Answer:
adapting can be learning from your environment and ways to survive etc.
Adapting can also go to sexual reproduction to survive diseases unlike asexual reproduction.
An adaptation is a trait which increases the relative fitness of an individual. The fitness of an individual has 3 components: 1. Probability of survival to reproductive age. 2. Probability of attracting a mate. 3. Average number of offspring. Any trait which increases the fitness of an individual by positively impacting one of these three aspects is considered an adaptation.
There are 2 types of adaptation: physical and behavioral. These are self-explanatory. Physical adaptations could include things like adaptations to morphology or physiology of an organism. Behavioral adaptations are adaptations to, well . . . behavior :)
6 Which of the following statements about shark teeth fossil evidence is not consistent with the scientific theory of evolution? (7 Points) A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks. B. Many fossils of Shał teeth have been found that show different sizes and serrations (saw-like edges). These fossil teeth have distinct differences and similarities to modern sharks. C. Many fossils of Shark scales have been found that have features of enlarged scales that resemble a brush. Our modern sharks do not have or need this type of scale to survive. D. A new shark fossil has been found that has characteristics in the size of the teeth and the serrations (saw-like edges) that are in between the older fossils found and the modern shark.
Answer:
A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks.
Explanation:
Evolution is the change in characteristics of a species over time and it relies on the process of natural selection.
The theory of evolution states that all species are related and gradually change over time.
Since all options except A show a change in the characteristics of shark teeth in the fossils found in relation to modern sharks, option A is the answer. Since, there is no change in characteristics between the Shark teeth in the fossils and that of modern sharks.
So, option A is the answer.

It has a positive impact on the environment by releasing chemicals into the environment.
It has a negative impact on the environment by allowing toxic chemicals to harm wildlife.
It has a negative impact on the environment by providing new niches for wildlife to inhabit.
Answer:
It has a negative impact on the environment by allowing toxic chemicals to harm wildlife
Mining affects the environment and has a negative impact on it, this type of human activity produces toxic chemicals that harm wildlife.
What are the impacts of mining?Mining has a significant impact on the environment, as the development of this activity almost always involves suppression of vegetation, exposure of the soil to erosive processes with changes in the quantity and quality of surface and underground water resources, in addition to causing air pollution.
With this information, we can conclude that Mining affects the environment has a negative impact on the environment, allowing toxic chemicals to harm wildlife.

46. If a species has experienced a genotype mutation that has greatly reduced its population size, but later the population increases, which of the following is most likely the consequence on the surviving population?
Organisms in the surviving population will be genetically superior, which will strengthen the population.
The natural selection of the surviving population will move from a normal selection to a disruptive selection.
The surviving population will be very different than the original population.
The surviving population will have very little genetic variation.
Answer:
Organisms in the surviving population will be genetically superior, which will strengthen the population
Explanation
Mutation are the fundamental forces of evolution,as they fuel the variability in the population
The following is most likely the consequence on the surviving population as Organisms in the surviving population will be genetically superior, which will strengthen the population.
What is genotype mutation?Mutation is the last supply of latest alleles in plant pathogen populations. Small populations have fewer alleles because of genetic glide and additionally due to the fact fewer mutations are generated in a small populace.
As a end result of the more occurrence of useful mutations, large populations of longer sequences can growth their health greater easily. It may also appear unexpected that populace length makes a distinction at mutation prices this small, however large populations have a bonus at numerous levels.

The heart pumps oxygenated blood to the _____ and deoxygenated blood to the _____. A) body:liver B) body:lungs C) brain:lungs D) lungs:nose Eliminate
Answer:
The Answer is B) body:lungs
Explanation:
The body sends oxygenated blood (blood enriched with oxygen) to the body where oxygen is used and blood becomes deoxygenated. This blood when received in heart is pumped to Lungs where oxygen is taken up by blood through alveoli in our lungs. This way deoxygenated blood gets oxygenated and is pumped to the rest of the body and the cycle repeats.
All other options are wrong as blood can only get oxygenated at lungs through small air chambers called alveoli where oxygenation takes place.

Research the Clements successional theory and answer the following questions.
Were any scientific investigations conducted for proposing the theory? Was this theory tested or simply expected?
Were there any objections to the Clements theory?
Has the theory been subjected to peer review and publication?
Did the scientific community accept the theory?
Answer: The theories are tested under the controlled conditions of the experimental set up. On the basis of the above description, we can say that the scientific investigations are done in the form of experimentation trials before proposing a theory. The theory is tested and is not simply expected.
A theory is a well-established, tested explanation that provides a unified description of some aspect of the natural world.
Henry Gleason objected to the Clements theory. He emphasized that succession is more dependent on abiotic factors and their interactions with the environment.
Yes, the theory was published and widely spread.
Nearly all (around 97%) of the scientific community accepts evolution as the dominant scientific theory of biological diversity. Scientific associations have strongly rebutted and refuted the challenges to evolution proposed by intelligent design proponents.
Clements described plant succession as a developmental process that ultimately resulted in a mature, or climax, community. This theory was tested, objected, and was not widely accepted.
What is Clements successional theory ?Clements concluded plant succession as a developmental process by which the community acquired well-defined series of stages.
This ultimately resulted in a climax community. The climax community was indicator and expression of the climatic conditions determining it.
Yes there were scientific investigations conducted for this theory.Yes this theory was first tested and not simply excepted. It was first tested for being theory of plant succession.Yes there were objections for this theory that expressed by Gleason. He assumed that identification in Clement theory of particular kinds of vegetation assumed to be of too much homogeneity.The theory was published but not widely among classical economists. It went through review before getting published.Thus, here one can conclude that Clements successional theory was tested, objected, and published.

The African savanna is a large grassland region with few trees that is hot and
seasonally dry. A population of lions and a population of wild dogs living there are
most likely to compete with each other for *
(1) mates
(2) water
(3) air
(4) sunlight
Answer:
Water.
Explanation:
OK for mates, it doesnt make sense cuz they are different animals, soo it's unlike for a lion to mate with a savanna dog.
For air, there is plenty, they arent trap in the same bubble (if you know what I mean)
And sunlight, its a large grassland and not alot of trees, so mostly likely they are in it all the time.
