Whitepunk [10]

Answer:

Option D

Explanation:

Options for the question

A)import seeds produced in the southern hemisphere.

B)plant the flowers out-of doors in november.

C)keep the plants in a warm growing environment.

D)expose the plants to an hour of light in the middle of each night until the end of april.

Solution

Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.  

Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time

Option D is correct

Can you use mass alone to predict whether an object will sink or float? Explain.
natima [27]

Answer:

No, you need both mass and volume to determine its desity to see if it can float.

Explanation:

Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.

Describe how waves superpose on each other using specific examples from two types of waves.
anastassius [24]

Answer:Towhen two waves if nearly same amplitude and same wavelength interfere with each other that time a new wave is formed with a different amplitude this phenomena is known as superposition. If two waves interfere with each other in same phase that time amplitude of resultant wave   wave is greater than the component waves and this type of interference is known as constructive interference. And when waves suprpose in opposite phase that time amplitude of resultant wave is less than the component waves and this type of interference is known as destructive interference.

Example: light waves, water waves, sound waves etc
