Answer:
cephalocaudal sequence
Explanation:
The cephalocaudal theory refers to the general pattern where the greatest growth occurs at the top of the body, i.e. the head, and gradually the physical development shifts downward: e.g. back, arms, spine, etc. It is a general pattern of physical and motor development with a continuum from infancy to puberty and follows a development pattern from head-to-toe.
Answer:
75%
Explanation:
In order to understand this question you need to understand the matching law first. The matching law provides the density of reinforcement or the rate of reinforcement if more than one response is available simultaneously to the individual. Here, two responses are available which are left key, 60 reinforcers per hour, and right key, 20 reinforcers per hour. This provides the ratio between the two reinforcers which is 60:20 or 3:1 in favor of left key. Here, one has to make a prediction only for left key and based on 3:1 ratio it can be said that 75% of pigeon will make their responses on the left key.

Answer: D) It shot air into the molten iron, making it hotter and eliminating impurities.
The Kelly-Bessemer process consists of removing impurities from the iron by oxidation with air that is blown through the molten iron. This raises the temperature of the iron mass and keeps it molten. The Kelly-Bessemer process was the first inexpensive industrial process for the mass production of steel.
The process is named after the inventor Henry Bessemer in 1856, although it is said to have been independently discovered by American inventor William Kelly in 1851.
