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 how many times a fungal cell divides in 24 hours, divide the total minutes in 24 hours by the time it takes to divide:

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

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

Protein is digested in the stomach.

To test if the burgers contain protein, Biuret reagent would be used.

When evaluating the use of meat versus meat-free burgers, several factors should be considered:

Nutritional Content

• Meat burgers typically contain more protein, which is essential for growth and repair of tissues. They also tend to have higher fat content, which can lead to health issues such as coronary heart disease (CHD) if consumed in excess.
• Meat-free burgers usually have more fiber, aiding digestion and preventing constipation. However, they may lack certain essential amino acids that are more readily available in meat.

Health Implications

• Diets high in saturated fats from meat burgers can increase the risk of obesity and related diseases like type 2 diabetes.
• on the other hand, meat-free burgers often promote a healthier lifestyle due to lower fat content and higher fiber, potentially reducing the risk of weight gain and chronic illnesses.

Environmental and Ethical Considerations

• Meat production is linked to higher greenhouse gas emissions and ethical concerns around animal welfare.
• Meat-free burgers, made from plant-based ingredients, contribute less to environmental degradation.

Personal Preferences

• Some individuals might prefer meat-free options due to taste or dietary restrictions, while others might prefer the flavor of meat burgers.

In conclusion, both types of burgers can fit into a balanced diet. However, meat-free burgers may provide more health benefits and lesser environmental impact, while meat burgers offer more protein but with potential health risks due to their fat content.
