Hypothesis: If the tire pressure for a car is set at the manufacturer's recommended amount, the gas mileage of the car will increase.

How would you test this hypothesis?​

Answers

Answer:

Seems more like a physics question but anyways

Explanation:

Tyre air pressure as recommended by the manufacturer ensures less energy application in moving your car, and easy movement of the engine means low fuel gulping. Regular air pressure check not only improves fuel efficiency but also results in smoother handling and better control of your car.

Which TYPES of cell transport go AGAINST the concentration gradient? list all possible so not just active!

Answers

The type of cell transport which go against the concentration gradient requires energy. This type of transport includes active transport which have some important functions in cell.

What is Active Transport?

During active transport, substances move against the concentration gradient i.e., from a region of low concentration to a region of high concentration. It is known as active transport because it requires the use of energy (ATP).

There are two main types of active transport: primary active transport that uses ATP, and secondary active transport that uses an electrochemical gradient.

In the digestive system, proteins are digested into amino acids.
Describe what happens to any of these amino acids that are in excess, and how their breakdown product is removed from the body.

Answers

Answer:

Amino acids are transported to the liver during digestion and most of the body's protein is synthesized here. If protein is in excess, amino acids can be converted into fat and stored in fat depots, or if required, made into glucose for energy.

A hypothesis is an educated guess based upon observation. It is an
explanation of a single event based upon what is observed. A hypothesis has not
been proved but can be supported by experimentation.
a) Suppose that out of 10 trees planted in a yard, only five survived. What kind of
hypothesis could you make about this observation or event? Remember that a
hypothesis needs to have a certain format.
b) How could you test this hypothesis? What type of experiment could you perform?

Answers

a) My hypothesis is in this case is that the environmental conditions in the yard were too extreme which resulted in half of the trees dying.

b) I can test this hypothesis by asking myself, what environmental conditions were the trees in that caused half of them to die? I could read about different biomes and their climates and learn how well they support organic life such as grass, plants, crops, and even trees. I can then determine that half of the trees did not survive due to the extreme environmental conditions they were in.

Here you go!

If you don’t give a tree enough light, then it will die. you can do an experiment where you put one tree in an area where there is no sun, and put another tree in a well lit area. this will show that only the tree that views the sun grows.

explain between glucose and glycogen and the role of the liver maintaining the blood glucose

Answers

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.

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.

What is an investigational hypothesis?

An investigational hypothesis can be defined as a plausible explanation about the observation of phenomena that occur in the real world which must be tested by experimentational procedures in order to confirm or reject them.

During the scientific method, we raise questions that may be answered by confirming hypotheses, a process that leads to collecting empirical evidence in favor of such ideas.

Therefore, we can conclude that hypotheses such as for example if pollutants may affect global warming by acting as greenhouse gases can be solved by using the scientific method, which involves making experiments to confirm or reject the hypothesis.

Suggest why the quantity of water vapour in expired air is always high?

Answers

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.

Water vapour makes up 0.02 to 0.04% of the air we breathe. Water vapour makes about 5.0 to 6.3% of 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.

Answers

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.

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?

Answers

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

Answers

Photosynthesis makes the glucose that is used in cellular respiration in order to make energy molecules in the form of ATP.

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.

Why was performing a baseline Passat necessary to interpret the results of your experiment

Answers

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).
