The correct answer is A.
Muscles need energy to produce contractions. The energy is derived from ATP (which stands for adenosine triphosphate) that is present in muscle cells.
Muscles tend to contain only limited quantities of ATP. When depleted, ATP needs to be resynthesized from other sources namely creatine phosphate (CP) and muscle glycogen. Other supplies of glycogen are stored in the liver. The body is also able to resynthesize ATP from lipids, i.e. free fatty acids. Different sources of energy are used depending on intensity and duration of the workload .
Answer : The correct answer is - bilateral symmetry, coelomates, and four levels of cell organization (cells, tissues, organs, organ systems).
Bilateral symmetry is a body plan of a life form according to which an organism can be divided into two equal halves (right and left half), only when it is cut through midline/central axis of the body. It is present in most vertebrates.
Most of the vertebrates exhibit four levels of cellular organization that are cell, tissue (group of cells performing similar function), organ ( made up of different types of tissue), and organ system (made up of different organs, working together in coordination).
Most vertebrates are coelomates, meaning that they have a fluid filled true body cavity, which is lined by mesoderm and possesses digestive tract and different body organs.
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
Our blood contains a large proportion of the iron in our bodies. Because women lose blood during a period, they also lose iron. This means that they need more iron in their diet to counteract this.
They uncover evidence of crimes, mostly things involving dna like finger prints or blood.
