The one for the cells is the
cells need to be able to get oxygen gas nutrients and get carbon dioxide out quickly.
i’m not sure for the other ones
NAD+ is the answer hope it helps have a good day
Ecosystems have living creatures A biosphere has water and no landforms
This is physics, electricity.
I'll break it down for you, very easy:
you have to use the formula V=IR
where V= voltage in volts (V)
I= current in Amperes (A)
R= resistance in ohms (Ω)
so what you require is I, current there you have to rearrange the formula to subject current;
I=V/R
=9/5= 1.8Ω (ans)
Since feces are alkaline elements, thet raise water's pH levels. Since feces have a pH level no higher than 7, they are acidic.
A - since this beaker contains fish feces, the red litmus paper will remain red, and the blue one will start to get red
B - since there is nothing affecting the water's pH in this beaker, both litmus papers will remain the same colour, since water is a neutral liquid.
Hope it helped,
