Answer:What traits does the kingdom protists fall under
Explanation:
All protists are eukaryotic organisms. ...
Most protists are aquatic, others are found in moist and damp environments.
Most are unicellular, however, there are a few multicellular protists such as the giant kelp.
They may be autotrophic or heterotrophic in nature.
The biogeochemical cycle that includes the process of buffering ocean pH and photosynthesis is the carbon cycle.
The biogeochemical cycles show the movement of matter in nature. These cycle show us that indeed matter is neither created nor destroyed but is always changed from one form to another.
The carbon cycle shows the movement of carbon in nature. An important component of the carbon cycle are the sinks of carbon. There are two important sinks of carbon dioxide in the carbon cycle which are oceans and green plants.
Green plants require carbon dioxide for photosynthesis while carbon dioxide is absorbed in the oceans as bicarbonate and carbonate ions where it helps to buffer ocean pH.

Answer:
Cardiac muscle tissue
Explanation:
Myocardium or heart muscle is a special type of muscle (differ than striated and smooth) and it is the main tissue of the walls of the heart.
Heart muscle consists of individual heart muscle cells (cardiomyocytes) which are joined together by intercalated discs. It also contains collagen fibres and other substances that form the extracellular matrix.
Heart muscle has a "special" mode of contraction: action potential triggers the release of calcium ions from the cell's internal store, the sarcoplasmic reticulum.
Deep inside the core of the sun, protons can collide into eachother with enough speed that they stick together to form a helium nucleus and generate a big amount of energy at the same time.
