Answer:
Its either B or C but I would go with C
Explanation:
If decomposers were removed from an ecosystem the ecosystem would collapse due to the lack of nitrogen and carbon available to producers.
What are decomposers?" Decomposers are organisms, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material."
Why are decomposers important for the ecosystem?Decomposers play a critical role in the flow of energy through an ecosystem:
They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Decomposer bacteria are responsible for fixing nitrogen in the soil, meaning they transform nitrogen into a form that can be used by other organisms in the food chain.Decomposition is also important because it is part of the global carbon cycle. The carbon cycle is the cyclical movement of carbon atoms from the atmosphere to the biosphere/lithosphere and back to the atmosphere.What is an ecosystem?"An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life."
What is a producer?"Producers are autotrophs, or organisms that produce their own food. Plants and algae are examples of producers."

The effectiveness of insecticide by the end of the spray program would have decreased.
What is an Insecticide?This is a chemical substance specially prepared to kill insects such as mosquito, fly etc.
These insects develop resistance to this chemical with time which thereby leads to a decrease in its effectiveness.

Cells (A) and (F) show an early and a late stage of the same phase of mitosis. What phase is it?
Answer: (Note: You will find the stages in the attached files)
The phase is PROPHASE. Cell A is in early prophase, while cell F is in late prophase.
Explanation:
The prophase might be divided into early prophase and late prophase.
Early-Prophase: The chromatin is condensed enough to distinguish individual chromosomes. There are also two pares of centrioles located outside the nucleus. They begin the separation from each other, migrating to the opposite poles. The microtubules extend and originate the polar fibers of the mitotic spindle. By this time, nucleoles have already disappeared. In the A cell, you can see the condensing chromatin and the centrioles migrating to the poles, but not there yet. You can also see the intact nuclear membrane and no nucleole. Late-Prophase: The nuclear membrane breaks and disperses. Chromosomes keep condensing until they are completely condensed and in direct contact with the cytoplasm. Each pair of centrosomes is already in the cell poles, and the polar fibers of the mitotic spindle are completely developed, as well as the kinetochore fibers. In the F cell, you can see centrioles in the poles and the noticeable mitotic spindle. You can also see the nuclear membrane broken into many pieces and the chromosomes that are completely condensed.Cell A is at the beginning of prophase, while cell F is at the end of prophase.
We can arrive at this answer as follows:
In cell A, we can see that the chromatin has gone through a strong process of condensation, to the point where we can see the individual chromosomes. This is an intrinsic feature of the beginning of the prophase.Furthermore, the nuclear membrane is still visible in cell A, which is also a characteristic of prophase.In the cell F, we can see the disintegration of the nuclear membrane, the condensation of chromosomes, and the contact of chromosomes with the cytoplasm. This is a characteristic of the end of prophase, where a new phase of the cell cycle will begin.In this cell, it is also possible to see the mitotic spindle and the existence of centrioles at the poles, which is also a characteristic of the end of prophase.You have not shown the picture your question refers to. However, it is possible to find it in questions similar to yours.

Choose the words or phrases that correctly complete the sentence. Two boys are holding onto the ends of a long piece of string, and they move it up and down to make a wave. They begin to move the string faster and faster. When they move the string, the energy (remains the same / increases / decreases) and the frequency (decreases / increases / remains the same). A) increases, increases B) remains the same, remains the same C) decreases, decreases D) increases, decreases
Answer:
The correct answer to the question above is option A "increases, increases"
Explanation:
From the question, the wave discussed is in a string, the wave traveled from one end to the other that makes it a transverse wave because as the string is being moved up and down it creates a disturbance which is at a right angle to the direction of travel. The energy generated by the wave in the string has a relationship with its frequency. Though the waves on a string can be fast once the tension that exists in the string is increased, it is important to note that the lower the frequency of a wave in a string, the lower the energy and that also translates that the tension in the string has also been lowered. So as the string moves faster the frequency and the energy increase.

How does overfishing affect the environment?The fishing enterprise affects a number of marine preservation issues, including fish populations, water pollution, and habitat degradation.
Some investigators have claimed that the size of the fishing industry needs to be seriously decreased in order to maintain healthy marine environments around the world.

https://brainly.com/question/5142437
Overfishing of Eastern Atlantic bluefin tuna in the Mediterranean is likely to result in decreased ecosystem stability due to disruptions in food chains and ecological balance. Thus correct option is A.
By significantly diminishing the population of a crucial species, such as the Eastern Atlantic bluefin tuna, overfishing has the potential to upset the ecosystem's delicate equilibrium.
Being the top predators that they are, the reduction of these tuna might result in an increase in the population of their prey, which would have a ripple effect across the entire food chain. This imbalance may lead to resource depletion, an overabundance of some species, and ultimately the instability of the entire ecosystem.
The most likely impact of overfishing on the environment is, in essence, option A. It's crucial to keep in mind that ecosystems are intricate, interconnected systems, and that the eradication or decline of one species may have reverberating consequences on the entire biological web.

withdrawal relfex
Explanation:
The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex that aimed to protect the body, stimulated by the presence of damaging stimuli such as heat.
When a person touches a hot object, the heat stimulates temperature and danger receptors in the skin, triggering a sensory impulse that travels to the central nervous system. The sensory neuron then synapses with interneurons that connect to motor neurons. Some of these send motor impulses to the flexors to allow withdrawal.

Answer:
According to the information given by Melinda on the chart, about the observed cells, cell X is an animal cell.
Explanation:
Animal cells are eukaryotic cells, with the ability to differentiate and unite to form tissues.
An animal cell contains elements such as a cell membrane, cytoplasm, nucleus and organelles —including mitochondria— by which it can be identified and differentiated from other cell types.
An important feature of animal cells is the existence of cytoplasmic compartments that form the endomebrane system, in relation to the cytoplasmic membrane and organelles.
