They can repair damaged immune systems and they make replacement heart valves.
This is an example of Nuclear Technology.
In nuclear technology, the atomic nuclei of radioactive fuel undergo nuclear reaction.
This means that the radioactive fuel undergoes nuclear fission (atomic nuclei separates or splits) or fusion (atomic nuclei fuses or joins).
Nuclear technology then generates atomic energy and releases it in the form of electricity.
Cell Y.
Answer: Option C.
<u>Explanation:</u>
Prokaryotic cells are the cells that do not possess a true nucleus. They do not even possess a membrane bound organelles. Organisms with in the domains bacteria and Archaea have prokaryotic cells. The other forms of life are the eukaryotic.
It is a unicellular organism. The word prokaryotic comes from a Greek word. The prokaryotic cells have a cell membrane or a plasma membrane which acts like a protective shield. Along with this, they also have a rigid cell wall which acts like further support and protection.
Answer:
Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria) while textbooks in countries like Great Britain, India, Greece, Brazil and other countries use five kingdoms only (Animalia, Plantae, Fungi, Protista and Monera).
Some recent classifications based on modern cladistics have explicitly abandoned the term "kingdom", noting that the traditional kingdoms are not monophyletic, i.e., do not consist of all the descendants of a common ancestor.
The correct answer is option (A) abundance of collagen fibers.
Bones are a type of supportive connective tissue forming an integral part of the skeleton. Bone tissue is made up of the different types of bone cells embedded in a matrix.
Bone matrix is mainly composed of the collagen fibres, also known as the ossein. They are fibrous protein units linked together rendering elasticity and improving fracture resistance. Collagen fibres are long, very flexible with a high tensile strength and resist stretching. They impart the characteristic resilience and strength, allowing it to withstand strong tension in case of bones, tendons, ligaments.
