How can i run for Club President if half of the people hate me?
LUCKY_DIMON [66]
Try to stay true to who you are and find a good reason as to why you should be a great leader such as if you are in any AP classes or if you have demonstrated good leadership skills in the past. And if everything else fails people like food so you could bake/cook something cool that's has to do with science. Good luck!

Which organelle carries substances to other parts of the cell?
STALIN [3.7K]
The answer will be Endoplasmic Reticulum (ER).

It is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

Well, to make it easier, endoplasmic reticulum is actually a fancy way of saying "cellular highway". I will explain to you why. I always like to study BIOLOGY relating our activities and our stuff. 

Okay, let's push aside cells. Let's think of us, humans. We can't stay in one place, we gotta moving all around the city. What do we use for moving around the city: either roads or sidewalks or footpaths.

Just like that, a cell also has a medium or road or a channel where all the substances can move around the cell. Well, its ER! So, from now on, everytime you are struggling with this difficult, L O N G word, just replace it with "cellular highway". The ER is like a water pipe, too. Water flows through it. Here, cellur substances flow through it. The ER is connected to the nucleus.

SUMMARY:

1# ER aka Endoplasmic Reticulum is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.

2# 
Try thinking it easy: replace it with "cellular highway".

3# 
It is much like the roads or sidewalks, we walk on.

When an atom or molecule gains one or more electrons, it is said to beA. reducedB. polarizedC. oxidizedD. energized
MArishka [77]
Ƒ An atom that gains one or more electronswill have a NEGATIVE charge. ƒ An atom that loses one or more electrons will have a POSTIVE charge. ƒ An atom that gains or losesone or more electrons is called an ION. ƒ A positive ion is called a CATION and a negative ion is called an ANION.

From this information above you can see its negative so it means it gets reduced
hope it helped

In this reaction the lead atoms gain anelectron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced
and as you can see oxidation only happens when oxygen is reduced
