Both mitochondria and ribosome are so tiny structure, it can not be seen under light microscope. It needs more magnification to study the detail structure, hence electron microscope is best to use.

<h3>What is ribosome ?</h3>

Ribosomes are small membrane less organelles and are the sites of protein synthesis.

It is present in are found in both eukaryotic and prokaryotic cells.

Ribosomes can either be present alone or in groups in cytoplasm while some ribosomes are attached to the endoplasmic reticulum  called as rough endoplasmic reticulum.

These are composed of ribosomal protein and RNA, have two subunit larger and smaller subunit.

New question: Indicate the location of DNA in eukaryotic cells.
Norma-Jean [14]
Explanation:

Most of the DNA is found in the cell nucleus but a small amount of DNA can also be found in the mitochondria and it is called mitochondrial DNA. Mitochondrial DNA, unlike nuclear DNA, is inherited from the mother, while nuclear DNA is inherited from both parents.

The nuclear DNA is found within a compartmentalized area within the cell called the nucleus. Each DNA molecule must be packed very tightly and precisely. This super-packaged form of DNA is called a chromosome.

we can conclude that the correct answer is:

Answer:The location of DNA in eukaryotic cells is:Cell nucleus as nuclear DNA.Mitochondria as mitochondrial DNA.

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.
