Coach wood's class is trying determine what factor is most important in the growth of earthworms. each day, they take the
metric length of four different worms in four different soil samples. today, it is moore's turn to measure the earthworms. for the
worm above, moore records a length of 6.0 cm. explain whether moore's recording is accurate and why.

a)the earthworm length is shorter than 6.0 cm because the worm is curved.

b)the earthworm length is shorter than 6.0 cm because moore used the
incorrect units.

c)the earthworm length is longer than 6.0 cm because the worm needs to
be straightened.

d)the earthworm measurement is accurate because moore subtracted the
beginning and ending points from the ruler.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
