Parasites live off living organisms, causing harm to obtain nutrients, like ticks or tapeworms. Saprotrophs, such as fungi and certain bacteria, feed on dead matter without harming living organisms. Parasites depend on hosts for survival, while saprotrophs decompose dead materials, returning essential nutrients to the environment. Understanding their differences helps grasp how parasites harm living hosts, whereas saprotrophs contribute to ecosystems by recycling nutrients from dead organic matter without causing harm.

Farmers grow fruits and vegetables in large greenhouses for advantages like controlled conditions. These structures regulate temperature, light, and humidity, allowing crops to grow throughout the year regardless of weather. Greenhouses shield plants from pests and diseases, reducing the need for harmful chemicals. They extend the growing season, resulting in more harvests annually. By fine-tuning conditions, farmers produce better-quality crops with higher yields. Greenhouses also use water efficiently, aiding in sustainable farming practices.
Asexual reproduction has different methods. Binary fission divides a parent cell into two, seen in bacteria. Budding, like in yeast and Hydra, forms new individuals from parent projections. Fragmentation, seen in starfish, involves breaking and growing new parts. Vegetative propagation in plants likRead more
Asexual reproduction has different methods. Binary fission divides a parent cell into two, seen in bacteria. Budding, like in yeast and Hydra, forms new individuals from parent projections. Fragmentation, seen in starfish, involves breaking and growing new parts. Vegetative propagation in plants like potatoes and strawberries creates new plants from roots or stems. Spore formation, as in fungi, produces specialized cells that grow into new organisms. Parthenogenesis, observed in some insects and reptiles, allows eggs to develop into offspring without fertilization.
To calculate the speed of the train, you can use the formula: Speed = Distance/Time Given: Distance = 240 km Time = 4 hours Plug the values into the formula: Speed = 240 km / 4 hours Speed = 60 km/h Therefore, the speed of the train is 60 kilometers per hour.
To calculate the speed of the train, you can use the formula:
Speed = Distance/Time
Given:
Distance = 240 km
Time = 4 hours
Plug the values into the formula:
Speed = 240 km / 4 hours
Speed = 60 km/h
Therefore, the speed of the train is 60 kilometers per hour.
To find the distance moved by the car between 8:30 AM and 8:50 AM, subtract the initial odometer reading from the final odometer reading: Initial odometer reading = 57321.0 km Final odometer reading = 57336.0 km Distance moved = Final odometer reading - Initial odometer reading Distance moved = 5733Read more
To find the distance moved by the car between 8:30 AM and 8:50 AM, subtract the initial odometer reading from the final odometer reading:
Initial odometer reading = 57321.0 km
Final odometer reading = 57336.0 km
Distance moved = Final odometer reading – Initial odometer reading
Distance moved = 57336.0 km – 57321.0 km
Distance moved = 15.0 km
Therefore, the distance moved by the car between 8:30 AM and 8:50 AM is 15.0 kilometers.
To calculate the time taken:
Time taken = Time at 8:50 AM – Time at 8:30 AM
Time taken = 20 minutes (since 8:50 AM – 8:30 AM = 20 minutes)
Now, to calculate the speed of the car in km/min:
Speed = Distance / Time
Speed = 15.0 km / 20 min
Speed = 0.75 km/min
To express the speed in km/h:
Since 1 hour = 60 minutes,
Speed in km/h = Speed in km/min * 60
Speed in km/h = 0.75 km/min * 60
Speed in km/h = 45 km/h
Therefore, the speed of the car during this time period is 0.75 kilometers per minute or 45 kilometers per hour.
Distinguish between a parasite and a saprotroph.

To find the distance moved by the car between 8:30 AM and 8:50 AM, subtract the initial odometer reading from the final odometer reading:
Initial odometer reading = 57321.0 km
Final odometer reading = 57336.0 km
Distance moved = Final odometer reading – Initial odometer reading
Distance moved = 57336.0 km – 57321.0 km
Distance moved = 15.0 km
Therefore, the distance moved by the car between 8:30 AM and 8:50 AM is 15.0 kilometers.
To calculate the time taken:
Time taken = Time at 8:50 AM – Time at 8:30 AM
Time taken = 20 minutes (since 8:50 AM – 8:30 AM = 20 minutes)
Now, to calculate the speed of the car in km/min:
Speed = Distance / Time
