haw are living organisms department on the soil?are organisms that live in water totally independent of soil as a resource
Answers
Answer:
Organisms are dependent upon soil. Plants/Producers takes up minerals and water from the soil . ... Organisms living in water are not independent of soil as resource as they also consume food that is made from soil directly or indirectly.
Soil forms an important element for the survival of living organisms. All living organisms, such as microbes, insects, humans and plants rely on soil to live. Animals rely on plant for food. Soil provides anchorage to the roots and for the plants to grow properly. Soil provides a habitat for many microbes and small animals, which in return increases the fertility of the soil by decomposing complex organic compounds.
Organisms that live in water are indirectly dependent on the soil. Some of the aquatic animals depend on the aquatic plants for their food. These plants require certain minerals for their growth. These minerals are carried to water bodies from soil by rivers, rain fall etc. In the absence of these dissolved minerals from the soil to these water bodies, aquatic plant would not be able to grow and thus, affect the aquatic food chain, eventually.

All of the following are characteristic of Pseudomonas aeruginosa EXCEPT Group of answer choices rod-shaped. production of pyocyanin. gram-positive cell wall. resistance to many types of disinfectants and antibiotics.
Answers
Pseudomonas aeruginosa is a gram-negative rod-shaped bacterium is characterized by the production of pyocyanin.
It is considered an opportunistic pathogen, meaning it mainly affects individuals with weakened immune systems. This bacterium is known to cause various types of infections such as pneumonia, urinary tract infections, wound infections, and sepsis, particularly in hospitalized patients.
One of the distinguishing characteristics of Pseudomonas aeruginosa is the production of a blue-green pigment called pyocyanin. This pigment is responsible for the green color observed on infected tissues. Pseudomonas aeruginosa is also known for its ability to form biofilms, a complex community of bacteria that are highly resistant to antibiotics and disinfectants.
In contrast to the statement in the question, Pseudomonas aeruginosa has a gram-negative cell wall rather than a gram-positive cell wall. Gram-negative bacteria are characterized by the presence of an outer membrane, which makes them more resistant to certain disinfectants and antibiotics. Pseudomonas aeruginosa is also known for its high resistance to many types of disinfectants and antibiotics, which makes it challenging to treat infections caused by this bacterium.
In summary, Pseudomonas aeruginosa is a gram-negative rod-shaped bacterium that is characterized by the production of pyocyanin and the formation of biofilms. It is highly resistant to many types of disinfectants and antibiotics, which makes it challenging to treat infections caused by this bacterium. However, Pseudomonas aeruginosa does not have a gram-positive cell wall, but instead has a gram-negative cell wall.

How are land breezes and sea breezes different?
Answers
Answer:
Land breezes come from land while sea breezes come from the ocean or other large bodies of water. The key difference is due to the property of water to retain heat and warm up longer as compared to land. Land breezes are also known as off-shore winds while sea breezes are also called on-shore winds.
Explanation:
Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense (i.e. warmer) and rises. The cooler air from the land moves in to take its place. Sea breeze: Sea breeze blows during the day and the land heats up faster than the sea.

Answers
Based on the information, it can be inferred that the concepts are organized from left to right as follows: Depression, Sleep area, River Flow East, and 2650 feet.
How to identify the correct space for each concept?To locate each concept in the correct space we must know how to read a topographic map. In this case, the depression would be the first concept because in the shaded area the contour lines are shown very close, this is generally related to a depression area in which the slope is very pronounced.
On the other hand, the sleeping area is at the top of the mountain at the bottom of the image because a flat region is shown on the top of the mountain.
Additionally, the blue line through the topographic map represents a river so this could be labeled River Flow East. Finally, the contour line that is at 2650 feet high would be the last space considering that each line represents an increase (or decrease) of 50 feet.

if dna of a particular species was analyzed and it was found that it contains 14 percent g, what would be the percentage of t? do not include the % sign in your answer.
Answers
If the DNA of a particular species contains 14% G, the percentage of T would be 72%.
If the DNA of a particular species contains 14% G, we can use Chargaff's rule to determine the percentage of T. According to this rule, the amount of A (adenine) in DNA is always equal to the amount of T (thymine), and the amount of G (guanine) is always equal to the amount of C (cytosine).
Therefore, if the DNA contains 14% G, it must also contain 14% C. This means that the remaining 72% of the DNA must be made up of A and T. Since A and T always pair up in DNA, the percentage of T would also be 72%.

If air and cloud were good conductor of electricity, do you think lightning could occur? Explain
Answers
Yes, lightning could still occur even if air and clouds were good conductors of electricity.
Lightning is caused by an imbalance of electric charges within clouds, or between the clouds and the ground. When this occurs, the electric bills will seek to equalize by transferring the excess charge to the opposite charge. The air and clouds are the media through which this charge is transferred, but the movement of the charge itself is what causes the lightning.
Therefore, even if air and clouds were better conductors of electricity, the imbalance of electric bills would still cause lightning. In addition, lightning is not just caused by the movement of electric charges through the air and clouds, but also by the build-up of static electricity. This static electricity is generated by the friction between air particles, or between the air and the clouds, and the resulting electric fields can cause lightning.
Therefore, even if air and clouds were good conductors of electricity, static electricity could still build up and result in lightning.

The enzymes are represented by 1 and 2 because they are joining and releasing after the product formation.
Enzymes are the biocatalysts that are responsible for the feasibility of the reaction and to increase the rate of reaction it is done by enzymes because they lower the activation energy which is needed by the substrate to move forward to make products and this is the minimum or threshold energy without which the substrate cant make products and if it is high then to lower
it enzymes help and also enzymes have the property of specificity as they will fix only with their substrate they are supposed to help to and also they work only at optimum ph and temperature because if there is even a slight difference the enzymes will not work properly and will denature or change their conformation so in the given diagram it can be seen that 1 and 2 are
enzymes because firstly 1 is combining with the substrate to form the enzyme substrate complex and in 2 the enzyme is being activated by using the hydrocholric acid and in 4th position also we can see that there are some enzymes which are being released as after the formation of products they are not needed anymore and enzymes are very important for all the cellular function to work properly.

Answers
The following is true about pancreas is b. It plays a substantial role in the digestion of proteins and carbohydrates.
The pancreas is an organ that is part of both the digestive system and the endocrine system, and it produces both hormones and enzymes that are essential to digestion. Option A is incorrect because the main duct of the pancreas opens into the duodenum, not the pylorus. The pylorus is the exit from the stomach into the small intestine. Option B is correct. The pancreas releases pancreatic juice, which includes enzymes that help digest proteins, carbohydrates, and fats.
Option C is incorrect because insulin is produced by the endocrine cells of the pancreas, which are separate from the exocrine cells that produce digestive enzymes. Option D is incorrect because the pancreas lies behind the stomach, not in front of it. So therefore among the given options, the true statement about the pancreas is B. it plays a significant role in the digestion of proteins and carbohydrates.

A typical power plant generate about 20 metric tons of high level radioactive waste per year. If 75% of this waste is U235 and the substance is considered safe when <100kg is remaining, how long would the waste need to be stored to be safe?
Answers
The high-level radioactive waste would need to be stored for approximately 3.55 billion years to be considered safe, assuming that 75% of the waste is U235 and the safe threshold is <100kg of remaining U235.
What is a radio active decay equation?If a typical power plant generates about 20 metric tons of high-level radioactive waste per year, and 75% of this waste is U235, then the amount of U235 generated per year is:
20 metric tons/year x 75% = 15 metric tons/year
To determine how long the waste needs to be stored to be considered safe (i.e., <100kg of remaining U235), we can use the radioactive decay equation:
\(N(t) = N0 * e^(-λt)\)
where:
N(t) is the remaining amount of U235 at time t
\(N_{0}\) is the initial amount of U235 (15 metric tons in this case)
λ is the decay constant of U235
t is the time elapsed
The half-life of U235 is 703.8 million years, which means that λ =\(ln(2)/t1/2\) = \(9.85 x 10^-10\) per year.
Substituting these values into the equation, we can solve for t:
\(100 kg = 15 metric tons * e^(-9.85 x 10^-10 * t)\)
\(ln(100 kg/15 metric tons) = -9.85 x 10^-10 * t\)
\(t = ln(100 kg/15 metric tons) / (-9.85 x 10^-10) = 3.55 x 10^9 years\)
Therefore, the high-level radioactive waste would need to be stored for approximately 3.55 billion years to be considered safe, assuming that 75% of the waste is U235 and the safe threshold is <100kg of remaining U235.
