You may talk about this picture:
A: it is an
ionic bond (which is a strong interaction, between two close atoms which has a large difference in their charges, like azote and oxygen)
B: is a
hydrogen bond (between O in a side and H in the other side)
C: it could be a
Van der Waals bond (small interaction between Carbon and hydrogen from different sides (London interaction))
D:
Hydrogen bond (between the Oxygen and hydrogen from different sides)
E: it's an
ionic bond
Answer:
The total length will be "10 units". A further explanation is given below.
Explanation:
The given points are:
R(−2, 4)
S(3, 4)
T(3, −1)
On applying the distance formula,

Answer:
Enzyme Activity- Responsible reactions Enzyme catalyze nearby substrates
Cell to Cell Recognition- Recognize molecules on surface of the other cells
Cell Signalling- A chemical messenger that binds a membrane protein causing to change shape and relay the message inside a cell.
Transport materials- Provides channels for a certain solutes to pass through membrane
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.
They are autotrophs that go through photosynthesis. Have no true, roots, stems or leaves.
