Answer:
2.They exhibit cell specialization.
Explanation:
A protist is an eukaryotic organism that can either be unicellular or multicellular. In the multicellular protist i.e. many cells, different types of cells are needed to bring about the organism's life processes. The different types of cells perform a specific different function in the organism.
The way that an organism makes it cells specialized to perform different functions is called Cell Specialization or differentiation. All multicellular organism, including a multicellular protist, contain many cells that have been specialized to perform different functions. Hence, the many cells of a multicellular protist will exhibit specialization in order to perform varying functions in the organism.
Answer:
Damaged muscle tissue is replaced by fibrous scar tissue. This is called as 'Fibrosis'. Thicker than the surrounding tissue, scar tissue is paler and denser because it has a limited blood supply; although it takes the place of damaged or destroyed tissue, it is limited in function, including movement, circulation, and sensation.
Dense irregular connective tissue contains fibroblasts scattered amongst randomly oriented collagen fibers, whereas muscular tissues contain multinucleated muscle cells that are able to contract upon stimulation. Because the connective tissue cells cannot contract, the muscle will lose strength, and so muscle function will become impaired.
Answer:
DNA helicase
Explanation:
DNA helicase unwinds the DNA strands by breaking the hydrogen bonds down at the center of the strand. this process begins in the replication fork of the DNA strand
Passive immunity because animals are passive.
The answer is B) Stromata
