Answer:
The Skeletal System is the system of structures that hold up your body. They keep you standing and hold a majority of your organs.

Answer:
Cyanobacteria
Explanation:
Cyanobacteria were the first photosynthetic autotrophs that used water molecules as the source of electrons. Cyanobacteria were the first autotrophs that performed oxygenic photosynthesis and carried out the splitting of water.
The process of splitting water released oxygen as a gas (O2) which was released in the atmosphere of the earth as a by-product. This led to the accumulation of oxygen in the atmosphere. Some cyanobacteria can fix nitrogen and have specialized cells called heterocyst which serve as the site for nitrogen fixation.
Answer:
Reactants: Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Products: Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

A verticle group (up and down) is called a GROUP. The horizontal groups (left to right) are called PERIODS
Even though Eubacteria and Archaebacteria look similar, differences in their ribosomal RNA led to their classification into different domains. They are domains of the old kingdom Monera.
<h3>What are Archaebacteria and Eubacteria? </h3>
Archaebacteria and eubacteria represent two different domains of the old kingdom Monera.
Monera is formed by unicellular prokaryotic microorganisms that do not have membrane-bound organelles and cell nuclei.
Both Archaebacteria and Eubacteria exhibit sequence variation in their ribosomal RNA, which can be used to classify them.
