Answer:
The correct answer would be - remain the same.
Explanation:
In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:
weight daily intake
132 2250
154 2450
176 2650
198 2850
220 3050
242 3250
In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.
Thus, the total calories he takes: 2700
burn by exercise: 295
should take: 2450
then = 2700 - (2450+295)
= 50 calories over the limit that will have negligible effect on the weight.
No it is not as it lacks internal cell membranes.
Answer:
Centre of Gravity
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.
Centre of Gravity in the Human Body
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.
Answer:
D. hotter rock rises and cooler rock sinks.
Explanation:
We know that as we move <u>towards Earth's center</u>, the <u>temperature rises</u>. This rise in temperature causes rocks to melt (magma). The high temperature and melting of rocks <u>decrease the density of material </u>which makes it <u>move upward</u>. By <u>moving upward</u>, the molten rock <u>starts turning solid</u> and becomes <u>denser again</u>. Here, it <u>sinks back due to gravity</u>. This upward and downward movement of rocks due to density and temperature makes a convection cell.
PS: The formation of convection cells in Earth's interior is also the reason for plate tectonics.
