Answer:
in the wall of the right atrium of the heart.
Explanation:
The sinoatrial node (SA), consisting of spindle-shaped cells, initiates the electrical activity of the heart. From its location in the right atrium in proximity to the superior vena cava, the electrical activity spreads to the atria, whose cells are larger than those of the SA.
Answer:
Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.
While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood.
Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.
Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

The answer would be: C) sexual selection.

It could be diverse in other cases, like a deeper croak in frog
Answer: by being smart and pog and swag
Explanation:
Plating is a producing procedure wherein a skinny layer of steel coats a substrate. this may be achieved via electroplating, which calls for an electric current, or via electroless plating, which is in the autocatalytic chemical method.
The two techniques have different effects. Coating involves the usage of paint, like a powder-lined end. The process of plating, mainly “electroplating,” includes passing cutting-edge through an electrolyte. It splits and deposits atoms on metallic objects, making them electroplated.
Like plating, the coating is applied to metallic surfaces for protective functions. however, unlike electroplated surfaces, powder-lined surfaces are basically blanketed in paint – not steel.
The plating procedure is a submit-manufacturing system. It involves the coating or overlaying of the surface of a workpiece with a skinny layer of metallic. The simple know-how of Plating to have a thin layer of one steel coating a substrate. therefore, the aim is to enhance the general quality of the product.
