Answer:
Oxygen (O2) concerntration
Temperature
pH
Simple problem my friend!
First we must replace X with -2,-1,0,1,2
then we plug in -2 in X. 8*-2 is -16 and adding 12 gives us a co ordinate of (-2,-4) now this is not enough so now we must do -1. 8*-1 is -8, + 12 gives us 4. so now our second co ordinate is (-1,4). i will do 1 more co ordinate and then you should be able to finish the problem by yourself :) we now plug in 0 to replace X. 8*0 is 0, easy and 0+12 is 12. so the third co ordinate is (0,12) when you have put all the dots on the graph be sure to draw a line through them and by the way, this is not a biology question lol, good luck!
Answer:
option A
Explanation:
ornithine is a non-protein and non-essential amino acid it is formed in plant by L-glutamate and in animals it is formed during the urea cycle by the catalyzation of arginine which is an enzyme. In vivo ornithine is not found in protein synthesis because it do not have any codon so it can not endoded by DNA but can be synthesized.
Ornithine is a precursor of glutamic acid, proline amino acid and citrulline amino acid
The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
