6-2(4+5)+6
First, you go off of PEMDAS, (parentheses, exponients, mutiply, divide, add, subract), and you will mutiply -2 to the numbers in the parentheses, -2x4 and -2x5. Which will then give you -8 and -10.
Then you set up your equation as normal, except without parentheses, which will make the equation 6-8+-10+6.
Then you will combine the two negative numbers, and it'll give you -18.
Then you will combine both the positive numbers, and that'll give you 12.
Add 12 to -18 and that will give you -6.
Answer:
The correct answer is - ENDOPLASMIC RETICULUM
Explanation:
In the cell, all cell organelle performs a specific function. Protein synthesizes with the help of ribosomes then they are sent to the endoplasmic reticulum for folding the proteins to their correct form or shape before sending them to the Golgi body for packaging.
Protein folding is an important function performed by the ER and must be correctly folded into particular 3-D shapes in order to function correctly and if not correctly folded then degraded by lysosomes.
A little trick i learnt: The atomic number reflects how many electrons there are, and there must be an equal charge. therefore, there are the same amount of protons as there are electrons. so if it has 81 protons, we look for number 81 in the periodic table, Thallium
