Which of the following should be a characteristic of a stable ecosystem?
O A high number of predators and a lesser number of producers
O A lack of interdependence of organisms
O An increase in human interference
O An abundance of biodiversity
Answer:
D
Explanation:
A is incorrect because that would make the prey species lesser and predators would die of starvation. If organisms were not dependent on each other then no herbivores would live there, then carnivores would die or leave. C is incorrect because human interference would lead animals to be reliant on humans, or pollution may occur. D is the only reasonable answer.
The correct option is D. An abundance of biodiversity is the characteristic of a stable ecosystem.
What is stable ecosystem?Sustainability has a crucial implication for ecosystem stability. Even in the face of disruption, the structure and operation of a healthy ecosystem ought to be steady throughout time.
The ecosystem ought to be able to quickly recover if a stressor or disturbance does cause it to change.
Frequency and intensity of disturbance (how often and what kind of tillage). The most stable ecosystems are found in oceans. Other terrestrial ecosystems experience modifications and biotic component succession. Oceans, however, are steady over a very long period of time.
Therefore, The correct option is D. An abundance of biodiversity is the characteristic of a stable ecosystem.

Your molecular clock model resembles another branching chart, the phylogenetic chart, which you've
used in this unit. Review the sample phylogenetic chart. What types of data are used to build a
phylogenetic chart? How do phylogenetic charts differ from molecular models, such as the molecular
clock model?
Answer: I do not know if this is correct, but this is what I answered.
Explanation:
Answer:
There are many types of data that a phylogenetic chart can use such as morphological data, such as structural features, types of organs, and specific skeletal arrangements; genetic data, such as mitochondrial DNA sequences, ribosomal RNA genes, and any genes of interest. Phylogenetic charts differ from molecular modes in many different ways such as the following. The phylogenetic charts considers various data types such as morphological data,molecule data, and behavorial data. On the other side, the molecular only considers one kind of data, that is, the genetic founded data.

what would have the greatest long-term impact on reducing the amount of carbon dioxide in the air
1. Decreasing the number of livestock on a farm
2.planting trees around a farm
4. Cutting down trees around a farm
5. Increasing the number of live stock on farm
Answer:
2 planting trees around a farm
Explanation:
afforestation is one of the ways to reduce carbon dioxide in the air because during photosynthesis carbon dioxide is absorbed by the plant which in return give us oxygen
PlLEASE HELP ME> I NEED THIS ANSWER RIGHT NOW. The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these oxygen-dependent organisms could no longer survive. How would you modify this investigation of the pond organisms to determine if the algal bloom really was the cause of the bass and crayfish die-offs?
Answer:
bacteria blooms and decreased underwater photosynthesis causes hypoxia, killing the fish. c. floating algae die, increasing sunlight penetration and heating the water. ... This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water

Which of these is an example of an environment in which natural selection would not occur?
Group of answer choices
A. There is genetic diversity in the population due to mutation and/or sexual reproduction.
B.All offspring have the same chance of survival.
C. Offspring inherit beneficial and detrimental traits from parents.
D. Some offspring have a physical trait that helps the organism compete more successfully.
An example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.
What is Natural selection?Natural selection may be defined as a type of strategy or process in nature through which organisms particularly gets better adapted to their environment and tend to survive and reproduce more than those less adapted to their environment.
Genetic diversity always favors the process of natural selection to occur. And this genetic diversity is generally induced by evolutionary forces like genetic drift, mutation, migration, etc.
Apart from this, offspring inherit beneficial and detrimental traits from parents and offspring have a physical trait that helps the organism compete more successfully and are also more prone to natural selection.
Therefore, an example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.

Deer are eating Mr. Thompson’s rose bushes. He puts a new deer repellent on half of his rose bushes and then waters them. He uses the same amount of water on the other half of his rose bushes but does not put the repellent on them. What is the control group for his experiment?
Answer:
Explanation:
What he is trying to do is see if the repellant does any good. So the roses that do not get the repellent are the control group.
If they become 1/2 chewed up, and the others do not, the repellent works.
We had deer that visited our property and their favorite flower was the tulip. They are very sloppy eaters -- no table manners at all. So it was evident that they had been there, I don't think they liked coffee and that's how the problem was solved.
They did not attack our vegetables (carrots which have a high natural sugar content), nor anything in the garden
Just the tulips around the house.

Hint
The answers are A B and C according to my sources…
An oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America is called the Nazca Plate, sometimes known as the Nasca Plate, after the Nazca region of southern Peru. Thus option A, B, C is correct.
What tectonic plate off the coast of the western US?The continent of North America is located on the oceanic plate to the east, while the Pacific Plate is the oceanic plate to the west. However, in the geologic past, there was another oceanic plate to the west known as the Farallon plate.
The triple junction will continue to be defined by the western margin of the North American plate along the Cascadia Subduction Zone as the boundary between the two plates.
Therefore, The Pacific Ocean is deeper than the other oceans of the world and the ocean levels are rising along the western coastline.
