Which of the following will cause an increase in the mass of an object?
Galina-37 [17]
I would say the answer would be the increase in the amount of matter present in the object. On earth there is a fairly good correlation between mass and weight. For example, a box containing diamond drill core will weigh more when the granitic rock is fresh and unaltered than when it is altered to lighter minerals like clay minerals (argillic minerals) as they are generally lighter than the parent feldspars like plagioclase, so the fresh granitic rock has more matter in it.

Why are there more debates then answers when discussing stem cell research
Talja [164]

Hello, Leah082656. There are many heated arguments over discussing stem cell research because of these two moral principals: the duty to prevent or alleviate suffering and the duty to respect the value of human life. In order to get embryonic stem cells, the embryo has to be destroyed. Although this is a huge controversial problem, by researching this could actually save and treat many other people. Some people are for it because it saves multiple people in the process, and some do not like this because it is killing an embryo. Whatever your stance is on this debate, these are the two sides that people debate over. I hope I helped!! Have a great day. :)
