Dna replication needs to occurs because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. so the dna needs to be copied before cell division so that each new cell receives full set of instructions. - Google
photosynthesis and respiration
A cell membrane is like a city border because it allows what comes in and out of the city.
One question is this supposed to be multiple choice?
This probably wont be the MOST accurate but this is the knowledge of a 6th grader (i tried)
Plants get their food from photosynthesising, they get their energy ffrom the sun and the chlorophyll is what capturers the suns energy. And once the suns energy has been caught then the electrons move around almost like they are excited to get the energy from the sun (the way some people get excited after consuming sugar a.k.a getting hyper) And the electrons are "jumping" in the thylakoid membrane. now there is enough energy to drive to the 2nd phase.
ADP becomes ATP that is when it is gaining more phosphate. Then the NADP gets more hydrogen to be able to store the energy now it has the hydrogen so it becomes.....NADPH. That is also kind of phase 3 the Calvin Cycle where G3P goes on to make glucose.
An animal gets energy from consuming the plants or other animals and sometimes even eating their own kind. Animals like deer, rabbits, moneys, pandas they all eat plants and or fruits. Because they get their energy from the plants and as said before that the plants get it from the sun. So basically all kinds of animals depend on the plants but some ocean creature dont really depend on plants but in some ways they do. Because not only for food, but for oxygen.
As you may have noticed i kinda know more about plants but soon i will be learning about animals since we are still learning about eukaryotic organisnisms.
Hope this helps. And have a great day! :)
