Answer:
Air speed of bird is 
mph
Explanation:
let the speed of the bird in still air be "X"
Speed of the bird when it flies in the direction of flow of wind 
Speed of the bird when it flies in the opposite direction of flow of wind 
The total time taken is equal to 
minutes
hours
The distance in miles is equal to 
miles
On solving the above equation, we get -
Air speed of bird is mph
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
Explanation:
It depends if you're talking about Physical Science or Physics/Biology -- so, I'll give both definitions (:
Physical Science: the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
Physics/Biology: a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
Hope that helped! (:
