You need to put up a picture
Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
Answer:
D. Selection has led to decreases in the size of fish at the age of reproductive maturity.
Explanation:
The larger body size of the fishes is not an adaptive trait as it reduces the survival chances of these fishes. The process of natural selection tends to increase the frequency of the traits that increase the survival fitness of the organisms. Here, the fishes with smaller body size at the reproductive age have greater chances of survival and would reproduce more to leave more progeny. Over the generations, the selection pressure would increase the proportion of fishes that are smaller during reproductive age.
The true descriptions regarding muscles are; Cardiac muscles and skeletal muscles are striated, heart (cardiac) and digestive (smooth) muscles are involuntary muscles, cardiac muscles work to pump blood. Skeletal muscles are the muscles that attach to the bones and their main function i contracting to facilitate movement of our skeletons. Smooth muscle are found in walls of hollow organs such as the stomach and are stimulated by involuntary action. While the cardiac muscles are found solely in the walls of the heart, they are highly specialized and under the control of of the autonomic nervous system.
