Suppose a student hypothesized that mice would grow best if fed apple slices. She used four mice, all of which she incubated for seven days. She fed the first mouse apple slices, the second raw steak, the third fruit punch, and the fourth was not given any food. At the end of seven days, she found the following changes in mass for the four mice: the one fed apple slices gained 1.00 g, the one fed raw steak gained 0.61 g, the one given fruit punch gained 4.20 g, and the one given only water died by week's end. Did the results of her experiment support her hypothesis?

Ответ:
NO, the result of her experiment did not support her hypothesis
Explanation:
Let's take an integral look about it; as we all know that an hypothesis is an educated guess which is proposed to give explanation of a particular event, usually they serve as the starting phase of investigation through carrying out experiments.
Now; a student hypothesized that mice would grow best if fed apple slices
HYPOTHESIS : MICE WOULD GROW BEST IF FED WITH APPLE SLICES.
EXPERIMENT: The experiment is carry out on four sample of mice, which was incubated for seven days. since we have four mice, we will denote them with A, B, C, D and what they were being fed with respectively.
MICE A APPLE SLICE
MICE B RAW STEAK
MICE C FRUIT PUNCH
MICE D WAS NOT GIVEN ANY FOOD
RESULT:
There result was based on the weight of their body after the experiment, definitely if the hypothesis was right, the result must support it. (i.e Mice feed with apple slice will have the greatest weight.
MICE A 1.00 g
MICE B 0.61 g
MICE C 4.20 g
MICE D dead
It is now obvious that the hypothesis is not valid since the result cannot support the hypothesis which says "Mice would grow best if fed ith apple slices", rather from our result, the Mice fed with fruit punch grow best.

溶酶體在細胞中具有若干重要功能。
1.他們消化吞噬作用吸收的食物,包括白細胞吞噬的寄生蟲
2.它們負責破壞磨損的細胞部分和細胞器,並使其組成分子返回環境,這一過程稱為自噬。
3.在凋亡(程序性細胞死亡)中起作用。這就是為什麼將它們稱為細胞的“自毀系統”或“自殺袋”的原因。如果它們破裂,酶會洩漏並消化細胞。當細胞被毒素,放射線等破壞時,這可能會通過凋亡或壞死而更容易發生。
4.它們還與質膜融合,以幫助修復受損的膜
溶酶體功能的任何異常均可導致嚴重的疾病,例如溶酶體貯積病,從而抑制有毒產品的分解,中樞神經系統,肝臟和腎臟異常,增加感染風險,並在早期死亡。
