In some countries, human waste is used as a fertilizer. If produce is grown in this type of fertilizer, it is possible that it will be contaminated with the protozoan that causes amoebic dysentery. One method of removing the protist without ruining the food is to place the produce in a 5% salt solution. Explain how this would kill the protist. How could you return them to normal?
The plant produce contaminated with the protozoan that causes amoebic dysentery when placed in 5% salt solution will kill the contaminants due to osmotic difference. The produce then can be brought back to normal by placing in pure water.
Amoebic dysentery is the disease caused by the microorganism called Entamoeba histolytica. The source of infection is human fecal matter. The symptoms of the disease includes abdominal cramps and diarrhea.
Osmotic difference is the difference of solute particles between two substances. When the protozoan cells are placed in salt solution, the salt solution has more solute particles that causes the secretion of water to the outside of protozoan cell, therefore causing its death by dehydration.

what does the model apply about the relationship between photosynthesis and cellular respiration
Photosynthesis makes the glucose that is used in cellular respiration in order to make energy molecules in the form of ATP.
What is the difference between photosynthesis and respiration?We know that photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as a food product which is used by plants and oxygen as a by-product. The process of cellular respiration converts oxygen along with glucose into the water and into carbon dioxide. Actually, water and glucose are the by-products, and ATP (adenosine triphosphate) is the energy that is transformed from the process.
The energy released by photosynthesis is stored during the process of cellular respiration. During photosynthesis, the food is broken down during the process of cellular respiration.
So we can conclude that photosynthesis removes carbon dioxide from the atmosphere while cellular respiration again brings carbon dioxide.

explain between glucose and glycogen and the role of the liver maintaining the blood glucose
In response to the pancreatic hormones insulin and glucagon, the liver helps maintain blood glucose levels. Glucose enters the liver after a meal, and blood glucose levels rise. This excess glucose is handled by glycogenesis, which occurs when the liver converts glucose into glycogen for storage.
What is blood glucose?Glycemia is the concentration of glucose in the blood of humans or other animals. It is also known as blood sugar level, blood sugar concentration, or blood glucose level. A 70 kg person's blood contains approximately 4 grams of glucose, a simple sugar, at all times. A fasting blood sugar level of 99 mg/dL or less is considered normal, 100 to 125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes. The main sugar found in your blood is blood sugar, also known as glucose. It is the primary source of energy in your body and is derived from the food you eat. Your blood transports glucose to all of your body's cells, where it is used for energy. Diabetes is a disorder in which your blood sugar stations stand too elevated.To learn more about glycogen, refer to:

The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.
What role does the liver have in maintaining blood glucose?By converting glycogen into glucose, a process understood as glycogenolysis, the liver produces sugar or glucose. By gathering amino acids, waste materials, and lipid byproducts, the liver can also produce the glucose or sugar that is required. Glucose 6-phosphatase catalyzes the buffering effect of liver glycogen to maintain blood glucose levels. Glycogenolysis in muscles converts glucose 6-phosphate into glycolysis without wasting any adenosine triphosphate (ATP), as this enzyme is exclusively found in the liver.By balancing the uptake and storage of glucose through glycogenesis with the release of glucose through glycogenolysis and gluconeogenesis, the liver plays a crucial part in this process. The numerous substrate cycles in the main metabolic pathways of the liver are crucial in controlling the generation of glucose.The excess glucose exists dealt with by glycogenesis in which the liver transforms glucose into glycogen for storage.

Which elements make up a water molecule?
hydrogen and nitrogen
oxygen and nitrogen
oxygen and carbon.
hydrogen and oxygen
Answer:
Hydrogen and Oxygen: The liquid condition of H2O at standard pressure and temperature is referred to as "water."
Explanation:
The polar chemical component and molecule known as water is a liquid at normal pressures and temperatures. According to its chemical composition, each molecule of water has one oxygen atom and two hydrogen atoms. Due to their polarity, water molecules can form up to four hydrogen bonds with molecules close by, regardless of whether they are in a liquid or solid state. Hydrogen bonds are roughly ten times stronger than the Van der Waals force, which attracts molecules to one another in most liquids. This explains why water has far higher melting and boiling points than other compounds that are analogous to it, including hydrogen sulfide.
Water contains numerous distinctive biological characteristics that are essential for the growth of life. It does this function by enabling organic chemicals to interact in ways that eventually permit replication. Water is essential to all known kinds of life. Water is crucial for many bodily metabolic processes as well as serving as a solvent in which many of the body's solutes dissolve. Anabolism and catabolism together make up metabolism.

Why was performing a baseline Passat necessary to interpret the results of your experiment
Performing a baseline Passat was necessary to interpret the results of your experiment because a baseline expedites our start-up process, improves our understanding of the task, and enables us to spot data irregularities.
A baseline is a straightforward model that, while not requiring a lot of knowledge or time to construct, yields respectable performance on a task. Pretrained convolutional neural networks for vision-related tasks, logistic regression for categorizing structured data, recurrent neural networks, and gradient-boosted trees are examples of baseline models that are frequently used (Ameisen 2018).
A baseline is imperfect due to its simplicity. For instance, the bag of words model for language modeling does not account for the sequence in which the words appear in each phrase; as a result, it lacks a great deal of structural information. Additionally, a lot of baselines rely heavily on model-integrated heuristics or solid modeling assumptions (i.e., linear models).

Suggest why the quantity of water vapour in expired air is always high?
Not all of the oxygen in the air is taken up by the lungs, and that the gases released when someone breathes out are heated to body temperature and saturated with water vapour. This results in the expired air having a larger water vapour content.
Why does expired air contain more oxygen?All of the oxygen in the air we breathe does not enter our lungs during the breathing process. The amount that is absorbed is little. Therefore, some oxygen is present in expired or exhaled air.
Since we don't consume nitrogen, the percentage of nitrogen remains close to 78%, but the significant difference is the rise in carbon dioxide. More or less 4% of the carbon dioxide and a larger percentage of water vapour than breathed air are found in exhaled air.

A DRAWBACK of living in a
group is . . .
A. more likely to be eaten by predators.
B. having to look out for yourself.
C. being less obvious to predators.
D. increased competition for food and mates.
Answer: D
Explanation:
The drawback of living in a group is the increased competition for food and mates.
Option (D) is correct.
When individuals live in a group, they often have to compete with other group members for limited resources such as food and potential mates. This competition can create challenges and reduce the availability of resources for each individual within the group.
Living in a group can have advantages, such as enhanced protection against predators (option C) and increased vigilance through cooperative behavior (option B). However, the drawback arises from the fact that resources within an environment are finite, and when individuals live in close proximity, they must compete for those limited resources.
This competition can range from competing for access to food sources to competing for mating opportunities. Individuals within a group must invest time and energy in acquiring and defending resources, which can lead to increased stress, lower reproductive success, and potential conflicts within the group.
Thus, the increased competition for food and mates is a notable drawback of living in a group.
