How does critical night length control photoperiodism?
Photoperiodism is the response of the plant to daylight and darkness. For short day plants it will bloom in darkness and when darkness exceeds critical night length, for long day plants it will bloom during daylight and when darkness is less than the critical night length.
How is the length of a phylogenetic tree determined?
The length of a phylogenetic tree is determined by the amount of genetic differences or changes that have occurred over time between different species or groups of organisms. These differences are typically measured using molecular data, such as DNA sequences, and are used to calculate the evolutionary distance between species on the tree. The longer the branches on the tree, the greater the genetic differences between the species.
What is the difference between long day and short day plants and how do their growth patterns vary based on the length of daylight they receive?
Long day plants require a certain minimum amount of daylight to flower, while short day plants need a specific maximum amount of daylight. Long day plants flower when days are longer than a critical length, while short day plants flower when days are shorter than a critical length. The growth patterns of these plants vary based on the length of daylight they receive, with long day plants flowering in the summer when days are longer, and short day plants flowering in the fall when days are shorter.
What are the physiological differences between gay and heterosexual men?
In general, there are none. Some research has hinted that there may be differences in the hypothalamus, and other research has hinted that there are differences in finger length, but these studies are early and need more work.
What is a latent period?
The latent period is the time between when a stimulus is applied and when a response occurs. In physiology, it refers to the delay between the start of a muscle contraction and the actual movement of a limb. In microbiology, it can also refer to the delay between exposure to a pathogen and the onset of symptoms.
What are the differences between surfaces?
The surfaces are the same length and have different material.
What are some differences between rifles and muskets?
Length, rifling (sometimes)
How does critical night length control photoperiodism?

Does the sun's position in the sky affect the length of daylight?
Yes, the sun's position in the sky affects the length of daylight. The angle at which the sun's rays hit the Earth's surface changes throughout the day due to the Earth's rotation, which in turn affects the length of daylight hours.
Whats the length of daylight in Kansas City on June 21?
The Length of Daylight in Kansas City on June 21st in 14 Hours
What is the length of a long response?
Any response length prohibitively long to be considered a short response
What is the length of daylight associated with the equinox at the equator and the poles?
At the equator, during the equinox, the length of daylight is approximately 12 hours. At the poles, during the equinox, there is no daylight as it is the period when the sun remains below the horizon for a full 24 hours.
What is the length of the daylight on the moon?
Two weeks
What are daylight and nighttime hours all over the world?
Daylight and nighttime hours vary around the world due to time zone differences and the tilt of the Earth's axis. At any given time, some parts of the world are experiencing daylight while others are in darkness. The length of daylight and nighttime also changes throughout the year due to the Earth's orbit around the sun.
What is critical night length?
Critical night length is the duration of darkness required for a plant to initiate or cease a biological process such as flowering or seed germination. It varies among plant species and is important for regulating their growth and development in response to changes in daylight.
Which location has the least variation in the length of daylight hours?
All places that are on the Equator have the least variation in the length of daylight hours.
In the US the month with the shortest length of daylight is?
December.
