Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.
The correct answer of the given question above would be the third option: THE EVOLUTION OF POPULATIONS OVER TIME. What is represented by the base of a phylogenic tree is the evolution of populations over time. It is also known as the evolutionary tree. This tree shows the evolutionary relationships among species.
Answer:
B. into an aquifer
Explanation:
People can obtain groundwater by drilling a well into an aquifer.
An aquifer is a porous and permeable formation where groundwater can be found.
- Aquifer is usually found below the water table.
- In this regard, the pore spaces of this layer of the earth allows for the storage of ground water.
- When the aquifer is punctured, groundwater can be abstracted.
Answer: This symptom is called the ADHD Hyperactive - Impulsive type
Explanation: The full meaning of ADHD is attention-deficit/ hyperactive disorder. It is believed that ADHD is genetic. It is a chronic behavioural disorder that is diagnosed in childhood and can continue into adulthood. Children diagnosed with this disorder experience difficulty with paying attention, sitting still, they fidget, they are hyperactive and easily distracted. We have 3 types of ADHD, they are:
a) ADHD the combined type
b) ADHD the Hyperactive -type
C) ADHD the inattentive and distractible type.
