Cross bridge formation between myosin heads and actin molecules is caused by the elevation of calcium ion concentration in the c
almond37 [142]

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.

How is the formation of of gametes in males similar to the formation of gametes in females
ioda

Gametes are the cells used during sexual reproduction to produce a new individual organism or zygote. The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.

Correctly match the following: - fibrous joint between radius and ulna - fibrous joint that unites bones of the skull - articula
topjm [15]

Answer:

- fibrous joint between radius and ulna: C. syndesmosis

- fibrous joint that unites bones of the skull: H. suture

- articulation between teeth and bone: J. gomphosis

- joint with a cavity between bones: E. synovial

- the epiphyseal plate: F. synchondrosis

- articulation between two pubic bones: A. symphysis

- permits opposition and reposition:  B. saddle  

- fibrocartilagenous fluid filled sacs outside the joint cavity: G. meniscus

- most common degenerative joint disease: D. osteoarthritis    

- movement of the sole laterally:  I. eversion  

Explanation:

The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.

In 3-5 sentences explain how increases in the human population impacts water resources. provide specific examples in your answer
astra-53 [7]

An increase in human population negatively impacts the water resources. There is only a small amount of clean and drinkable water on Earth. If more people are on Earth, more of this water will be used by the population. An increase of people also means that more fossil fuel will be used.

<h3>How does human population impact water resources?</h3>

Population growth especially will limit the amount of water available per person, because an increase in per capita water consumption driven by development will intensify water demand, straining the local water supply.
