The correct answer would be D) An observation that has a number associated with it.
<span>This research study would be a prospective cohort study. </span>
<span>In this study, the groups are different in some way, for example, a control group which received no treatment, a standard group who received a well-studied drug and a test group who received a new drug. These groups are followed over time and the outcome (such as curing a disease or alleviating symptoms) will be compared. </span>
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
Answer:
yup Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.
Explanation:
Answer:
1.The eyes, a sensory organ, see the ball.
2.Sensory nerves transmit the information to the brain.
3.The brain processes the information.
4.The brain sends signals to the motor nerves.
5.Motor nerves carry the signal to the hand muscles.
Explanation:
When we receive a stimulus by any of our 5 senses (sight, touch, smell, hearing or taste) our body will react to this. Once that the stimulus is received ( in this case seeing the ball) a signal is send through the sensory nerves to the brain. In the brain the information will be processed and an answer will be given through the motor nerves in order to move the muscles and catch the ball. All this process is made in seconds.
