Answer: A concentration gradient must exist
Explanation: Think about it this way. If you want movement in a tub of water, the water can't be flat. This would mean it was very stable. But if there is an inequality on the water levels of the tub, meaning that one side was much higher than the other, then the water would "diffuse" and try to get flat. Same with cells. I hope that explanation somehow made sense, it made more sense in my head then written out...
mountains
depressions
discontinuities
The answer is depressions. I just completed the quiz.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.
Exceeding the maximum growth temperature of an organism can lead to the breaking of hydrogen bonds, denaturation of proteins and the over-fluidization of cell membranes.
At temperatures higher than the maximum growth temperature for an organism, d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid. When the temperature exceeds the maximum threshold for an organism, this exerts stress on the cell causing various biological consequences. For instance, hydrogen bonds within molecules can get disrupted, which can lead to protein denaturation. This means that the proteins lose their functional 3-dimensional shape, a process that can sometimes be irreversible. Moreover, excessive heat can increase the fluidity of cellular membranes to an extent such that they cannot function properly anymore, making the cell unviable.

The downfall of a tragic character is the result of "a tragic flaw".
The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.
Hamartia refers to a tragic flaw that causes the downfall of a hero.
Answer:
Option B
Explanation:
In almost all the literature forms specially in greek literature, a hero has always been a person who has rises against all the odds in his/her life. This special character faces affliction and usually shows strength instead of the risk involved in it. Some time this character undergoes complete down fall or he/she get ruined but this "hero" rise up again and stand strongly against the destruction and thus is perceived as a tragic hero. Aristotle, has always portrayed in his writing "hero" as the main character who get ruined because of destiny or some social reason
Hence, option B is correct
c. midbrain.
b. cerebellum.
d. cerebrum.
Answer:
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface

bones
Answer:
The correct answer would be bones.
X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.
In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.
Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.
It forms glowing pictures on the X-ray film or photographic film.
The denser the material the brighter the image will be formed on the photographic film.
