which process does not occur within a mitochondrion in a eukaryotic cell?

Answers

The process that does not occur within the mitochondria of a eukaryotic cell is glycolysis. I can conclude this because I believe you are referring to the options for this question which are:

A) Krebs cycle

B) Glycolysis

C) ATP synthesis

D) Electron transport chain

Glycolysis is a process in which glucose in the cytoplasm of a cell is broken down to produce energy in the form of ATP. The word glycolysis means "glucose splitting".  It is one of the stages of cellular respiration. In fact, it is what begins this process.  

Glycolysis is an anaerobic process meaning it does not need the presence of oxygen to function properly. Although this is a very important process and does participate in the creation of ATP, it does not occur in the mitochondria, but rather in the cytoplasm of a cell.

Adult male polar bears are expected to weigh, on average, 370 kg. A polar bear's primary source of food are seals and other marine animals, which they hunt from a platform of sea ice. Scientists are concerned that global warming is melting these platforms earlier in the year, reducing the time polar bears are able to hunt and forcing them inland without the necessary fat reserves built up to survive summer and fall. The US Geological Survey (USGS) conducted a study in the Southern Beaufort Sea to investigate whether climate change has appeared to negatively impact the weight of polar bears. Eighty-three adult male polar bears were captured between March and May of the years 1990 and 2006 and their weights were recorded. The sample mean weight was 324.6 kg, and the sample standard deviation was 88.3 kg. Use the sample results to estimate the standard error of the sampling distribution of sample mean weight.

Answers

The estimated standard error of the sampling distribution of the sample mean weight is approximately 9.8 kg.

To estimate the standard error of the sampling distribution of the sample mean weight, we can use the sample standard deviation (88.3 kg) and the sample size (83). The standard error is calculated using the formula:

Standard Error = Sample Standard Deviation / √(Sample Size)

Substituting the values into the formula, we have:

Standard Error = 88.3 kg / √(83)

Calculating the standard error:

Standard Error ≈ 88.3 kg / 9.11

Standard Error ≈ 9.68 kg

Rounding to one decimal place, the estimated standard error of the sampling distribution of the sample mean weight is approximately 9.7 kg.

Therefore, based on the given sample data, the standard error suggests that the sample mean weight of adult male polar bears (324.6 kg) is expected to vary around the true population mean weight of 370 kg with an estimated standard deviation of 9.7 kg. This indicates the potential variability or uncertainty in estimating the true mean weight of polar bears based on the limited sample data provided.

Answers

Answer:

See the answer below

Explanation:

The appropriate NaCl concentration for IV fluid is 0.9% NaCl.

This is because this concentration of NaCl is isotonic to the human body and is safe to be administered as an intravenous fluid into the body.

An isotonic solution is a solution that is neither too concentrated for the cells of the body to lose water into the surrounding solution nor too diluted for the cells to start absorbing water from the surrounding solution. The solution is in equilibrium with the cytosols of the body cells.

Red blood cells are produced more frequently than the other types, the body produces them every second, hence option 2 is correct.

Why do red blood cells produce more frequently?

Medication that promotes the formation of RBCs: Erythropoietin is a hormone that is made in the liver and kidneys and stimulates the production of RBCs in the bone marrow. Some types of anemia can be treated with erythropoietin.

In order to replace those red blood cells that eventually deteriorate and die, red blood cells are continuously created in the bone marrow. A red blood cell has a lifespan of roughly 120 days on average. Anemia and shortness of breath result from a large drop in the number of red blood cells.

Therefore, It just takes a few weeks to replenish red cell reserves because your body produces roughly 2 million new ones every second.

The carbon 'that makes up organic molecules in plants is derived directly from combustion of fuels carbon fixed in photosynthesis carbon dioxide produced in respiration carbon in the lithosphere coal mines

Answers

The carbon 'that makes up organic molecules in plants is derived directly from b. carbon fixed in photosynthesis.

During photosynthesis, plants take in carbon dioxide from the atmosphere and use it to synthesize organic molecules, such as sugars, starches, and cellulose. The carbon in these organic molecules comes directly from the carbon dioxide that the plant has fixed during photosynthesis.

Respiration, on the other hand, releases carbon dioxide into the atmosphere as a byproduct, so it does not directly contribute to the carbon that makes up organic molecules in plants.

While the lithosphere does contain carbon in the form of minerals and fossil fuels like coal, plants do not directly incorporate this carbon into their organic molecules. However, when fossil fuels are burned, they release carbon dioxide into the atmosphere, which can then be used by plants during photosynthesis.

High blood pressure: High blood pressure puts extra strain on your heart and blood vessels, and is a major risk factor for heart attacks and strokes.

High cholesterol: High levels of cholesterol in your blood can increase your risk of heart disease, as it can build up in the walls of your arteries and form plaques that block blood flow.

Lack of physical activity: People who are inactive have a higher risk of heart disease, as physical activity can help to lower blood pressure and improve cholesterol levels.
