Answer:

Organizing the Human Body
Alinara [238K]

Answer:

Cell----- Tissue----- Organ---- Organ system

Explanation:

All living organisms are made up of cells. However, multicellular organisms contains many different kinds of cell, which are required to perform certain roles that will be of utmost benefit to the organism as a whole. The level of organization of life follows an hierarchical classification.

As earlier stated, CELLS are the simplest unit of every living organism. Cells that come together to function in a similar role are called TISSUES. Tissues that work together collectively form an ORGAN. Organs that perform similar functions to achieve a similar goal are called the ORGAN SYSTEM. The different systems in a multicellular organism makes up the whole ORGANISM.

Hence, Cell----- Tissue----- Organ---- Organ system is the organized level of organization from the smallest (cell) to the largest (organ systems).

In order to provide nutritional information about food, scientists must evaluate how many calories a given food has per serving
Mashutka [201]

Answer:

                 

Explanation:

I am the thing that goes bump in the night. The shadow-like figure all are too afraid to identify in their room. The silent stalker of your waking nightmares and lucid dreams. Do not worry, I can- but will not- hurt you. Your family, however, doesn't have such luck. Do not warn them that I will be following their every move, or it will lead to a grizzly fate for you and your bloodline. I hope that my message has given you closure for the events to come.

In the meantime, you can pray for your family. Maybe I'll have mercy.
