The muscle contracts when ATP supplies energy for thing filaments in a muscle fiber to slide over thick filaments. The correct answer is A.
Answer:
Symbiosis
Explanation:
Another category of interactions between organisms has to do with close, usually long-term interaction between different types of organisms. These interactions are called symbiosis
Explanation:
<u>the Paleozoic Era </u>
The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.
Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

Answer:
"Long, bitterly cold, dry winters and short, cool, damp summers define the boreal forest climate. The boreal forest is alive with activity. In the winter, their conical forms decrease snow buildup on branches, preventing them from breaking under the weight of the snow."

If the solution becomes transparent we could assume that ; The solution was hypotonic and the cells had burst.
<h3>Tonicity of red blood cells </h3>
To test for Tonicity of red blood cells, we placed the cells in a solution.When red blood cells are placed in hypotonic solution there is high rate of osmosis in which the solvent flows into the red cells placed in the solution the cells will experience a process known as Hemolysis and these cells do not diffuse light, the solution becomes a red transparent solution.
Hence we can conclude that If the solution becomes transparent we could assume that ; The solution was hypotonic and the cells had burst.
