Ответ:
true for the first one and I think false for the 2nd one
Ответ:
1. "In Human beings, cells are structured differently base on what they need to do". The
answer is True.

1. Cells are structured that are like basics buildings blocks of all living beings.
For sure, depends on which place the cells are include: brain, heart, lungs, stomach etc.
But, in the other hand, Cells have a basic structured like the following: cytoplasm; cytoskeleton; endoplasmic reticulum; Golgi apparatus; Lysosomes and Peroxisomes; Mitochondria; nucleus; Plasma membrane and Ribosomes.
Based on this information above adduced, you can see that we have a lot of
functions about the cells in human beings, but we have cells inside the plants too.
2. The integumentary system is a set of structures that covers all external coating the
entire human body. But, like this assertive is saying that cover the entire human body,
independent which place of body: external or internal and on vertebrate this external
coating calls Skin and the color of all kind of Skins depends on the amount of
