When an ATP synthase is inhibited by a metabolic poison, the H+ concentration in the mitochondrial membrane rises, lowering the pH. As a result, the graphed line decreases gradually, indicating that pH decreases over time.
H+ would be pumped across the membrane into the intermembranous space, increasing the pH difference between the matrix and the intermembranous space. Because H+ cannot flow back through ATP synthase because the enzyme is constricted by the poison, the difference across the membrane will continue to increase rather than remain constant. Eventually, the concentration of H+ in the intermembranous space would become so high that no more H+ could be pumped against the gradient.

What word means "between the dorsal wall and peritoneum” and refers to the location
of the kidneys?
Answer: The kidneys are situated in between posterior abdominal wall and partial peritoneum.
Explanation:
Kidneys are located at the dorsal side of the body of vertebrates including humans. These are located opposite to the spine. The location of the kidney is the retroperitoneal space that lies in between the posterior abdominal wall and partial peritoneum. Peritoneum is the serous membrane which forms the lining of the abdominal cavity. It also covers the kidneys from the dorsal side. The kidneys are well protected by muscles and fat at the dorsal side.
Energy extraction and the complete oxidation of foodstuffs requires three stages. The energy extracted from fuels is converted to ATP. Select the statements that are true for the different stages required for energy extraction and complete oxidation of foodstuffs.
A. In the first stage, macromolecules are converted to monomers, and a small amount of ATP is produced.
B. In the first and second stages the majority of ATP needed for cellular processes is produced.
C. In the third stage, fuel molecules are completely oxidized to CO2 , and most of the ATP needed for cellular processes is produced.
D. In the third stage, fuel molecules are completely oxidized to CO2 , and a small amount of ATP is produced.
E. In the second stage, monomers are broken down, and a small amount of ATP is produced.
F. In the third stage, fuel molecules are completely oxidized to CO2 , and no ATP is produced.
Answer:
C. In the third stage, fuel molecules are completely oxidized to CO2 , and most of the ATP needed for cellular processes is produced.
Explanation:
The three stages in the generation of energy from the oxidation of foodstuffs are given below:
First stage - This stage is the preparation stage and no useful energy is produced in this stage. In this stage, large molecules in food are broken down into smaller units. Proteins are broken down to amino acids, polysaccharides to simple sugars such as glucose, and fats are broken down to glycerol and fatty acids.
Second stage - In this stage, the various small molecules from the first stage are degraded to simple units (mostly acetyl-CoA) that are useful in metabolic activities of the body. Few ATP molecules are generated in this stage.
Third stage - In this final stage, most of the ATP required for cellular processes is produced from the complete oxidation of the acetyl unit of acetyl CoA to CO₂ in the citric acid cycle as well the oxidation of the electron carriers NADH and FADH₂ in oxidative phosphorylation.

The human body needs minerals to survive. Without
minerals, the body could not function properly. The minerals
that make up rocks are the same minerals that someone
might eat in a bowl of cereal! The body needs about 80
different types of minerals to function properly. Iron enriches
the blood, salt maintains fluid balance, calcium fortifies the
bones, and fluorine strengthens the teeth. Most vital
minerals can be absorbed into the body from eating plants
and lean meats. However, many food manufacturers add
minerals to their products to make them more desirable to
consumers. Eating a balanced diet can ensure that the
proper amount of these essential minerals is ingested.
Question:
The passage tells us that "many food manufacturers add minerals to their products to make them more desirable to consumers." Do you think that this is a good idea? What are the pros and cons?
Answer:
You have to put down what you think and not what other people thing
Explanation:
You can simply answer this question yourself by doing research or just thinking if its a good idea
Eating vegetables and lean meats can help the body absorb the majority of essential nutrients. However, many food producers add minerals to their products to increase customer appeal.
What are nutrients?Chemical elements known as nutrients are present in all living things on Earth. They are essential to the survival of all living things, including humans, animals, and plants.
The breakdown of food by nutrients provides energy for living things. They are utilised in every bodily function of an organism.
The majority of vital nutrients can be more easily absorbed by the body when veggies and lean meats are consumed.
To boost consumer appeal, several food companies do, however, add minerals to their products.
Although processing has many advantages, it can also be harmful and reduce the nutritional value of food.
For instance, blanching causes vitamin and mineral leaching losses. Additionally, during processing, milling and extrusion might result in the physical removal of minerals.
Thus, these are some pros and cons of the given scenario.

Organisms that live in similar environments, such as the ocean, often have similar adaptations. This is often due to
A. convergent evolution
B. coevolution Proton
C. gradualism
D. sexual selection
Answer:
A.
Explanation:
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time.
Organisms that live in similar environments, such as the ocean, often have similar adaptations, and this is often due to convergent evolution, which is in Option A, as convergent evolution is a process by which organisms that live in similar environments adapt.
What are coevolution and convergent evolution?Convergent evolution occurs because the same selective pressures are acting on the organisms, leading to the development of similar adaptations, such as streamlined bodies and fins, in many species of fish that live in the ocean and this is due to convergent evolution.
Hence, organisms that live in similar environments, such as the ocean, often have similar adaptations, and this is often due to convergent evolution, which is in Option A, as convergent evolution is a process by which organisms that live in similar environments adapt.

The temperature equivalent to 77°F is
°C.
Use the formula to convert the temperature.
Answer:
25 degree celcius
Explanation:
formula
(given degree Fahrenheit - 32)×5÷9
(77 - 32)× 5÷9
= 25°C
Here I will show you how to convert 77 F to C so you know how hot or cold 77 degrees Fahrenheit is in Celsius. The F to C formula is (F − 32) × 5/9 = C. When we enter 77 for F in the formula, we get (77 − 32) × 5/9 = C.
so therefore the answer is 25 degrees celsius

What happens in crossing over? Why is it important for sexually reproducing organisms, and what is one of the consequences of errors in crossing over?
Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

Scientists believe Polar Bears have evolved from a group of Brown Bears that became an isolated population during a time when the Earth's climate began cooling down.What are some adaptations that make Polar Bears different from Brown Bears and what do you think caused the adaptations to occur?
Answer:
One adaptation is white fur. There was probably one white cub born to a brown bear mother, and the fur helped camouflage it for safety and later, hunting. This bear would have been more successful in hunting in the arctic, so it was more likely to reproduce and pass on the white fur genes. A second adaptation is the long claws of brown bears that are used for digging through vegetation would have shortened to be safer on ice. Polar bear paws also have little sticky bumps on their paws for gripping ice.
A third adaptation is that polar bears don't hibernate in winter. In winter, there is a lot more food available to them, so they need to stay awake. A fourth adaptation is their hair is also now water repellent, because most of their food comes from the sea. A fifth adaptation is in their digestive system. Polar bears don’t digest carbohydrates as well as brown bears, because their diet has much more fat than anything else. Polar bears hunt seals and can convert the blubber into fat for their bodies to live off of when food is scarce.

These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.
Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
