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.

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.

does the environment create adaptations

Answers

As the environment varies, organisms adapt by changing their phenotypes, including morphological and behavioral traits. Such phenotypic responses to the environment are modified through the process of evolution, which gives rise to different forms of adaptation.

Any genetically based physiological, behavioral, or ecological trait that enables an organism to cope with, and to survive and reproduce in, its environment represents an adaptation. Some traits may not be adaptive but simply leftover vestiges of traits that once were adaptive.

why are antibiotics unhelpful for treating the common cold?

Answers

Why are antibiotics unhelpful for treating the common cold?

Antibiotics unhelpful for treating the common cold because they only fight bacteria, not viruses. However, a cold can sometimes result in a bacterial infection. In that case, antibiotics would be beneficial if they could prevent that type of infection.

ANTIBIOTICSAntibiotics are medications that aid in the prevention of bacterial infections. They accomplish this by either killing the bacteria or preventing them from replicating or reproducing themselves.Antibiotics are drugs that kill germs in your body.

Consider the following two statements about DNA melting temperature:
1) The melting temperature of a sample of DNA is the temperature at which 50% of the double helices in the sample have completely denatured.
2) A molecule with 53% GC base pairs would have a higher melting temperature than a molecule of equivalent length with 53% AT base pairs.
Determine which one of the statements below is CORRECT.
A. Statement 1) and statement 2) are false.
B. Statement 1) and statement 2) are true.
C. Statement 1) is true; statement 2) is false.
D. Statement 1) is false; statement 2) is true.

Answers

Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

Why is statement 1 false and 2 is true?

Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.

Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

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.

To learn more about overfishing affect click here:

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.

Cells (A) and (F) show an early and a late stage of the same phase of mitosis. What phase is it?

Answers

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.

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).

It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytosis. If fluid droplets are taken in, the processes is called pinocytosis.
