Answer:
or 0.0079.
Explanation:
Joyce is planting tulips in her garden.
Number of red (R) bulbs = 5
Number of white (W) bulbs = 5
Total number of ways to plant 10 bulbs in one row is


Cancel out common factors.

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.
Required outcomes are
RRRRRWWWWW and WWWWWRRRRR

Formula for probability:




Therefore the required probability is
or 0.0079.
Answer:
Glucose is a six-carbon sugar that is directly metabolized by cells to provide energy. ... A glucose molecule is too large to pass through a cell membrane via simple diffusion. Instead, cells assist glucose diffusion through facilitated diffusion and two types of active transport.

Answer:
sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone.

Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.
