Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
Answer:
Distributing replicated chromosomes to daughter nuclei.
Explanation:
I'm not sure what your options are, but distributing replicated chromosomes to daughter nuclei is a main role of mitosis:)
The egg example that Czerski uses to explain the law of conservation of angular momentum is that according to the principle of conservation of angular momentum, anything that is spinning will keep spinning until it is stopped.
Similarly, in the example of an egg given by Czerski If you spin a raw egg and then try to stop it by placing your finger on the shell, the egg will continue to spin since the uncooked portion of it is still in motion.
The law of conservation of angular momentum states that an object's angular momentum won't change in the absence of any external tension.
Its angular momentum is conserved as long as there is no net external torque acting on the system.
In forensic science, reconstruction of crime scenes is a crucial application of physics because instances involving accidents, body falls from heights, weapon projectile motion, bullet or tool case analysis, glass penetration of quick stone.
And law of conservation of angular momentum plays a great role in the reconstruction of those crime scenes and also in the firearm identification.
