Why is 37 degrees the optimum temperature for e coli growth

Answers

Answer 1

E. coli has adapted to grow best at the optimum temperature range most conducive to its optimal enzymatic activity and metabolic processes, allowing for efficient and rapid growth in the human body.

37 degrees celsius is the most appropriate temperature for e. Coli boom due to the fact it's miles the temperature at which e. Coli can successfully carry out its metabolic tactics, which include protein synthesis, DNA replication, and mobile division.

E. Coli is a mesophilic bacterium, which means that it prospers at moderate temperatures commonly found inside the human frame (around 37°c). At decreased temperatures, inclusive of the ones located in refrigeration (4°c), e. Coli boom is slowed, and at better temperatures, such as those found in fever (above 40°c), e. Coli boom is inhibited or may even die.

The cause why e. Coli can develop and divide maximum efficiently at 37°c due to the specific enzymatic and metabolic pathways it possesses. Enzymes are organic catalysts that facilitate the chemical reactions important for existing processes. The enzymes in e. Coli functions optimally at this temperature variety, making an allowance for efficient nutrient uptake, electricity production, and cellular replication.

A 23-in. Vertical rod cd is welded to the midpoint c of the 50-in. Rod ab. Determine the moment about ab of the 180-lb force q

Answers

The moment about ab of the 180-lb force q is 13,860 lb-in.

How to determine moment?

To determine the moment about AB of the 180-lb force Q, we need to find the perpendicular distance between the line of action of the force and point A, and then multiply this distance by the magnitude of the force. This perpendicular distance is called the moment arm.

First, find the coordinates of point C. Since the vertical rod CD is welded to the midpoint C of the rod AB, use the midpoint formula:

x_C = (x_A + x_B)/2

y_C = (y_A + y_B)/2

where (x_A, y_A) and (x_B, y_B) are the coordinates of points A and B, respectively. Plugging in the values:

x_C = (0 + 50)/2 = 25 in.

y_C = (0 + 23)/2 = 11.5 in.

So point C has coordinates (25, 11.5).

Next, find the moment arm. To do this, draw a line through point C perpendicular to AB, and extend it until it intersects the line of action of the force Q. Call the point of intersection point D. Use similar triangles to find the distance from A to D.

The triangle ACD is similar to triangle ABC, since CD is perpendicular to AB and AC is the altitude to AB. Thus:

AC/AB = CD/BC

Solving for BC:

BC = (AB)(CD)/AC = (50 in.)(23 in.)/(11.5 in.) = 100 in.

Therefore, the distance from A to D is 100 - 23 = 77 in.

Finally, calculate the moment about AB by multiplying the magnitude of the force by the moment arm:

M_AB = Qd = (180 lb)(77 in.) = 13860 lb-in.

Therefore, the moment about AB of the 180-lb force Q is 13,860 lb-in.

Which is not a general adaptation?
OA. Camouflage.
OB. Legs for walking.
OC. Wings for flying.
D. Streamlined shape to reduce friction.

Answers

Camouflage is not a general adaptation.

What is adaptation?

Adaptation refers to the evolutionary process through which organisms develop certain traits or characteristics that allow them to survive and reproduce in their environment. These traits can be physical, behavioral, or physiological and are shaped by natural selection.

Adaptations can be both structural, such as the long neck of a giraffe, or functional, such as the ability of some plants to tolerate drought conditions. They can also be behavioral, such as the way in which some birds build their nests, or physiological, such as the ability of some animals to regulate their body temperature in extreme environments.

Camouflage is a specific adaptation. It refers to an animal's ability to change the color or pattern of its body to blend in with its environment. It does not have the same universal application as other general adaptations, such as streamlined shapes to reduce friction or legs for walking.

Explain how the diffraction of light shows that light behaves like a wave.
Use key terms: Point source, circular wave pattern, and overlapping waves.

Answers

The way that light refracts is the same as how a wave would refract. The way that light diffracts is the same as how a wave would. Similar to how interference occurs in waves, it also occurs in light.

What evidence does light's diffraction provide that it behaves like a wave?

Light will shift directions as it travels from one medium, like the air, to another, like the ocean. Light behaves in a similar manner to other waves, like sound waves.

How does the phenomenon of diffraction affect how light behaves as a wave?

The bending and spreading of waves around a barrier is known as diffraction. Because you can bend and block out specific light waves, it has to do with how light behaves as a wave.

A roller couster turns in a circular path that has a radius of 25 meters, what's the fastest Velocity the roller coaster can travel without exceeding a centripetal acceleration of 16m/s^2

Answers

The fastest velocity that the roller coaster can travel without exceeding a centripetal acceleration of 16 m/s^2 is 20 m/s.

What is velocity ?

Velocity can be defined as the displacement of the object in unit time.

The centripetal acceleration (ac) of an object moving in a circular path with radius (r) and velocity (v) is given by the formula:

ac = v^2 / r

We want to find the maximum velocity (v) that the roller coaster can travel without exceeding a centripetal acceleration of 16 m/s^2, given that the radius of the circular path is 25 meters. We can rearrange the formula to solve for v:

v^2 = ac * r

v = sqrt(ac * r)

Substituting the given values, we get:

v = sqrt(16 m/s^2 * 25 m) = sqrt(400 m^2/s^2) = 20 m/s

Therefore, the fastest velocity that the roller coaster can travel without exceeding a centripetal acceleration of 16 m/s^2 is 20 m/s.

What is the problem with changing the force in the rubber band and the mass of the tub at the same time?

Answers

Changing the force in the rubber band and the mass of the tub at the same time can make it difficult to determine the effect of each variable on the motion of the tub.

What leads to changing forces?

Changes in the mass of an object: If the mass of an object changes, the force required to move it will also change accordingly. This is due to the fact that force is directly proportional to mass.

Changes in the speed or velocity of an object: This is because the kinetic energy of the object increases with an increase in speed, which requires more force to be applied to maintain the same rate of acceleration.

This is because the change in one variable may mask the effect of the other variable. Therefore, it is best to change only one variable at a time and keep all other variables constant in order to accurately observe and measure the effect of each variable on the system.

Just 45minutes earlier, it was effluent, piped over from Orange Countys wastewater treatment plant next door. Ata specialized plant, it then went through several stages of purification that left it cleaner than anything thatflows out of a home faucet or comes in a brand-name bottle.Its stripped down to the H, 2 and O, said Mike Markus, the general manager of the county water district.He was not exaggerating. Without the minerals that give most cities supply a distinctive flavor, this watertastes of nothing.As California scrambles for ways to cope with its crippling drought and the mandatory water restrictionsimposed last month by Gov. Jerry Brown, an array of ideas that were long dismissed as too controversial,expensive or unpleasant are getting a second look. One is to conserve more water; another is to turnnearby and abundant sources of water, like the Pacific Ocean, into drinking water through desalination.Yet another is to recycle the water Californians have already used. And therein lies a marketing challengethat can be even greater than the technological one.Water recycling is common for uses like irrigation; purple pipes in many California towns deliver water togolf courses, zoos and farms. The West Basin Municipal Water District, which serves 17 cities insouthwestern Los Angeles County, produces five types of designer water for such uses as irrigation andin cooling towers and boilers. At a more grass-roots level, activists encourage Californians to save graywater from bathroom sinks, showers, tubs and washing machines to water their plants and gardens.Enticing people to drink recycled water, however, requires getting past what experts call the yuck factor.Efforts in the 1990s to develop water reuse in San Diego and Los Angeles were beaten back by activistswho denounced what they called, devastatingly, toilet to tap. Los Angeles built a $55 million purificationplant in the 1990s, but never used it to produce drinking water; the water goes to irrigation instead.But with the special purification plant, which has been operating since 2008, Orange County swungpeople to the idea of drinking recycled water. The county does not run its purified water directly intodrinking water treatment plants; instead, it sends the water underground to replenish the areas aquifersand to be diluted by the natural water supply. This environmental buffer seems to provide an emotionalbuffer for consumers as well.The $481 million plant opened during a previous drought. It made us look like geniuses, Mr. Markussaid. The timing is right again. In the midst of the current drought, the county has completed a $142million expansion that will increase capacity by more than 40 percent, to 100 million gallons a day, and ata fraction of the cost of importing water or desalinating seawater. (A further expansion to 130 milliongallons a day is planned.)Now water reuse is being tried elsewhere around the country, including parched cities in Texas that dopipe treated water directly to their water supplies.

We regard them as unnecessary creatures that do more harm than good. Man continuously wages war on them, for they contaminate his food, carry diseases or devour his crops. They sting or bite without provocation, they fly uninvited into our rooms on summer nights, or beat against our lighted windows. We live in dread not only of unpleasant insects like spiders or wasps, but of quite harmless ones like moths. Reading about them increases our understanding without dispelling our fears. Knowing that the industrious ants live in a highly organized society does not prevent us from being filled with revulsion when we find hordes of them crawling over a carefully prepared picnic lunch. No matter how much we like honey, or how much we have read of the uncanny sense of direction which bees possess, we have a horror of being stung. Most of our fears are unreasonable, but they are difficult to erase. At the same time, however, insects are strangely fascinating. We enjoy reading about them, especially when we find that like the Praying Mantis, they lead perfectly horrible lives.

Last summer, I spent many days in the garden watching thousands of ants crawling up the trunk of my prized peach tree. The tree has grown against a warm wall on a sheltered side of the house. I am especially proud of it, not only because it has survived several severe winters, but because it occasionally produces luscious peaches. During the summer I noticed that the leaves of the tree had begun to wither. Clusters of tiny insects called Aphids were to be found on the underside of the leaves. They were visited by a large column of ants which obtained a sort of honey from them. I immediately embarked on an experiment which, even though it failed to get rid of the ants, kept me fascinated for twenty four hours. I bound the base of the tree with sticky tape, making it impossible for the ants to reach the Aphids. The tape was so sticky that they did not dare to cross it. For a long time, I watched them scurrying around the base of the tree in bewilderment. I even went out at midnight with a torch and noted with satisfaction and surprise that the ants were still swarming around the sticky tape without being able to do anything about it.
