Well, Herbert Spencer was the first one who write about the theory of Evolution (Before it was popularized by Charles Darwin, Herbert spencer is the one that theorized survival of the fittest)
hope this helps
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
Answer:
C.The percentage of essential body fat is the same for both males and females.
Explanation:
Among the given statements, only C is incorrect. Typically, on average, women have 5-12% more body fat than men. This has been mainly linked with the female hormones (e.g. oestrogen). Firstly, women can store more fat in their bodies due to the presence of excessive adipose tissues. Secondly, they are suppose to carry a child at some stage of their life, so a better food supply and protection is necessary.
On the other hand, rest of the options are true. Essential body fat is always required by body. It accounts for 3% of total body wight. And, it can be found in organs, bones and muscles at different percentages.
Answer: A. All animals are multicellular, all are heterotrophic, and all lack cell walls.
Explanation:
Its D. Sexual reproduction
