Step 3
How many times would this fungal cell divide in 24 hours?
Answer
To find out how many times the fungal cell divides in 24 hours:
- Calculate the number of divisions in 24 hours.
- There are 24 hours in a day, so:
rac{24 ext{ hours}}{1.5 ext{ hours/division}} = 16 ext{ divisions}
Therefore, the fungal cell would divide 16 times in 24 hours.

Evaluate the use of burgers made from meat compared with meat-free burgers in providing humans with a healthy, balanced diet.
Answer
When comparing meat burgers to meat-free burgers, several factors must be considered:
Protein Content:
Meat burgers contain more protein (14.0 g) per 100 g compared to meat-free burgers (9.0 g), which is essential for growth and muscle repair.
Fibre Content:
Meat-free burgers are higher in fibre (5.5 g) than meat burgers (0.9 g), which aids in digestion and may prevent constipation, contributing to overall health.
Fat and Cholesterol:
Meat burgers have higher fat content (16.0 g) and cholesterol (120.0 mg), increasing the risk of heart disease, while meat-free burgers contain significantly less fat (5.2 g) and no cholesterol (0.0 mg).
Carbohydrate Content:
Both types provide similar carbohydrate content (around 15 g), beneficial for energy.
In conclusion, while meat burgers offer higher protein, meat-free options are healthier overall due to lower fat, cholesterol, and higher fibre content, aligning better with a balanced diet.
