Answer/Explanation:

The replication of DNA is semi-conservative, as each new molecule of DNA inherits one of the parental strands each, and one new strand each. DNA is replicated using the enzyme DNA polymerase, which synthesises a new strand by adding nucleotides in a sequence through complementary base pairing with the template strand. This occurs before the mitosis stage of the cell cycle, where the cell divides. Before this cell division happens, the cell has to pass certain checkpoints controlled by enzymes which ensure environmental conditions are optimal for dividing, and that the new DNA is free from errors.

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.

Which change of state is shown in the model?
Eduardwww [97]

Answer:

The answer is: deposition

Explanation:

The answer is: deposition

● Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.

One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase cha
