Answer:
The parietal layer of the serous pericardium is also known as the epicardium of the heart wall.
Explanation:
The pericardium is a sac composed of two layers which surround the pericardial cavity. The two layers of the pericardium are the fibrous and serous pericardium and the serous pericardium is further divided into two layers: the visceral and the parietal layers.
The fibrous pericardium is composed of the thick connective tissue and thus prevents overfilling of the ventricles.
The parietal pericardium lines the internal surface whereas the "visceral pericardium layer" is the innermost layer and is known as the epicardium of the heart wall.
Thus, the selected option is correct.
Answer:
Simple, and Stratified.
Explanation:
Simple epithelial tissue: They are only one cell layer thick in nature, and are present in places where filtration and absorption are necessary. These tissues include the lining of blood vessels and the female ovary body cavities.
Stratified epithelial tissue: They are two or more cell layers thick in nature because these tissues are consist of several layers of cells so, they are present in places where protection is important. These tissues include the lining of the bladder, urethra, and esophagus.

To a 1st Grader:
Carbon is the magic element that is the basis of life on Earth. All living things contain carbon. Animals breathe it out, and plants breathe it in. Plants, people and animals depend on each other.
The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Plants take carbon dioxide from the air along with water and photosynthesis from the sun and use it to make food.
Explanation:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. To a first grader is different because they wouldn't understand what half of these words mean lol.
