Answer:
Smooth muscle fibers have an oblong shape, much like a football. They’re also thousands of times shorter than skeletal muscle fibers. Similar to skeletal muscles, cardiac muscles are striated. They’re only found in the heart. Cardiac muscle fibers have some unique features.
Explanation:
The correct answer is proteins.
The oxidative phosphorylation in the eukaryotes takes place within the mitochondria with the help of electron transport chain. The main objective of the electron transport chain is to accumulate enough amount of protons in the intermembrane space so that there will be a concentration gradient which would help in the production of ATP.
The electron transport chain comprises of various molecules, but majorly the proteins, which are situated in the inner membrane of the mitochondria.
Answer:
Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass. But many other elements, such as the various biometals, are present in small amounts. Sometimes polymers are also known as macromolecules or large-sized molecules. Usually, polymers are organic (but not necessarily). A monomer is a molecule that is able to bond in long chains.

Understand?
Well when writing a CER first you need to state your claim after stating your claim you need to support your claim with evidence from your sources and after that you need to give reasons on how your evidence supports your claim
<h2><u>Answer:</u></h2>
Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.
It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.
As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.
