Name one structure in Figure 10 which is present in both plant cells and fungal cells but not in animal cells - AQA - GCSE Biology - Question 8 - 2010 - Paper 1

The disease caused by a fungus is Rose black spot.

To calculate the number of times a fungal cell divides in 24 hours, we first determine how many 90-minute intervals fit into 24 hours:

$ext{Number of divisions} = \frac{24 \text{ hours} \times 60 \text{ minutes}}{90 \text{ minutes}} = 16$

Thus, the fungal cell divides 16 times in 24 hours.

Protein is digested primarily in the stomach.

The chemical used to test for protein is Biuret reagent.

When evaluating meat burgers versus meat-free burgers, several factors must be considered:

Nutritional Content

• Meat burgers typically contain more protein, which is essential for growth. However, they also contain higher levels of fat and cholesterol, which can contribute to health issues like coronary heart disease (CHD) and obesity.
• Meat-free burgers are often higher in fiber, which aids digestion and can help prevent constipation.

Health Implications

• The high fat content in meat burgers can lead to health risks, necessitating medical interventions like stents or medications for cholesterol management.
• Meat-free burgers may be a healthier choice for individuals concerned about heart health but may not provide the same protein levels.

Ethical Considerations

• Production of meat burgers raises ethical concerns about animal welfare and the environmental impact due to methane emissions from livestock.
• Some people prefer meat-free burgers for ethical reasons or due to dietary preferences, making them a popular choice.

Overall Impact

Consumers should weigh the nutritional benefits against the health risks and ethical considerations when choosing between these two types of burgers.
