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 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.
To calculate the distance Salma travels from her house to school, you can use the formula: Distance = Speed x Time Given: Time taken = 15 minutes = 15 minutes × (60 seconds / 1 minute) = 900 seconds Speed of the bicycle = 2 m/s Now, use the formula to find the distance: Distance = Speed x Time DistaRead more
To calculate the distance Salma travels from her house to school, you can use the formula:
Distance = Speed x Time
Given:
Time taken = 15 minutes = 15 minutes × (60 seconds / 1 minute) = 900 seconds
Speed of the bicycle = 2 m/s
Now, use the formula to find the distance:
Distance = Speed x Time
Distance = 2 m/s x 900 s
Distance = 1800 meters
Therefore, the distance between Salma’s house and her school is 1800 meters (or 1.8 kilometers).

Seeds disperse in several ways: Wind dispersal happens when lightweight seeds equipped with structures like wings or parachutes are carried by the wind, enabling them to travel far. Water dispersal occurs as buoyant seeds float on water, aiding their spread. Some seeds attach to animals or are ingested and dispersed through animal droppings. Others burst open to scatter seeds forcefully, while heavy seeds fall close to the parent plant. These methods help seeds reach new places for growth and survival.

While running, the motion of your hands includes two types: oscillatory and linear motion. The back-and-forth swinging of your arms is an oscillatory motion, similar to a pendulum’s repetitive movement. Simultaneously, your hands move in a straight line, aiding in your forward movement, which is linear motion. These combined motions help maintain balance, generate momentum, and assist in propelling your body forward while running.
The motion of a horse pulling a cart on a straight road is mainly linear, moving straight ahead along the road. The horse propels the cart in a straightforward path.

The motion of a horse pulling a cart on a straight road is mainly linear, moving straight ahead along the road. The horse propels the cart in a straightforward path. However, there might be slight swaying or oscillation in the cart due to uneven surfaces or movement, creating a subtle side-to-side motion. Despite this minor swaying, the predominant motion remains linear, as the horse and cart move forward in a straight line along the road.

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.
