Answer:
About 90 per cent of energy may be lost as heat (released during respiration), through movement, or in materials that the consumer does not digest. The energy stored in undigested materials can be transferred to decomposers.
It is larger in plant cells than in animal cells
Answer:
The correct answer is no.
Explanation:
The temperature of a person changes depending on their age, the physical activity they are doing and until the time of day.
There is an established average temperature that is 98.6 ° F (37 ° C) as a healthy temperature.
If the temperature exceeds 100.4 ° F (38 ° C) it means that you may be ill or have an infection.
The difference in temperature by age is very minimal, but it is still a difference. Let's see:
- Babies and children: from 97.9 ° F (36.6 ° C) to 99 ° F (37.2 ° C).
- Adults: from 97 ° F (36.1 ° C) to 99 ° F (37.2 ° C).
- Adults over age 65: 98.6 ° F (36.2 ° C).
Explanation:What is centripetal acceleration?
Can an object accelerate if it's moving with constant speed? Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.
Acceleration is a change in velocity, either in its magnitude—i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. You experience this acceleration yourself when you turn a corner in your car—if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. In this section we'll examine the direction and magnitude of that acceleration.
The figure below shows an object moving in a circular path at constant speed. The direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. This direction is shown with the vector diagram in the figure. We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration
