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
Answers
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.

Overfishing is causing the decline of fish populations, such as Eastern Atlantic bluefin tuna in the Mediterranean. Eastern Atlantic bluefin tuna are caught faster than they can reproduce. Which statement describes themost likely effect that overfishing will have on this ecosystem?
Answers
Overfishing decreases the stability of the ecosystem by disrupting food chains.
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.
Thus, Overfishing decreases the stability of the ecosystem by disrupting food chains.

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.

According to the information in the given chart, what type of cell is cell X?
a
prokaryotic cell
b
bacteria cell
c
animal cell
d
plant cell
Answers
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.
The other options are not possible because:
Bacterial and prokaryotic cells lack nuclei and organelles. Plant cells possess chloroplasts and cell wall, as described for the Y cell.what does homeostasis look like in a non human body

Explanation:
Answer:
1.) Water; carbon dioxide
2.) Sugar; oxygen
3.) Pigment
4.) An electron
5.) ATP, NADPH, and oxygen
6.) NADP+
Explanation:
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. Molecules called pigments absorb energy from light. The main pigment in photosynthesis is called chlorophyll. Chlorophyll exists in several different forms in different organisms. Chlorophyll a is the main photosynthetic pigment found in land plants and algae. A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to “donate” an electron. In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.
