Which advance in biology resulted from developments in cell technology?
Mariulka [41]

Answer:

Immortal cell line

Explanation:

An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular operation and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro

Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology.

Why is the sarcoplasmic reticulum. How does it aid in the stimulation of muscle contraction?
Mandarinka [93]
Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.
</span>Nervous stimulation causes a depolarization<span> of the muscle membrane (sarcolemma) </span>that<span> triggers </span>the discharge<span> of </span>calcium<span> ions from the sarcoplasmic reticulum.</span>

just olya [345]

Answer:

1. fragmentation- genetically identical

2. budding- genetically identical

3. haploid cells from two different mycelia fuse to form a zygote- genetically distinct

4. one hyphae creates spores through mitosis- genetically identical

Explanation:

1) Fragmentation is a form of asexual reproduction i.e. one parent, employed by certain organisms including fungi in which a FRAGMENT breaks off from the single parent to produce new cells. Since it is an asexual reproduction, the resulting cells will be GENETICALLY IDENTICAL.

2) Budding is another form of asexual reproduction that fungi undergoes e.g yeast. In the budding process, buds develop on the parent cell and later grow into mature cells that are GENETICALLY IDENTICAL to the parent cell.

3) In fungi, two different mycelia can produce haploid sex cells via the process of meiosis, which then fuse to produce a ZYGOTE. This method is a sexual means of reproduction. Hence, the zygote formed will be GENETICALLY DISTINCT from the parent.

4) Hyphae (threadlike filaments) of a fungi can via MITOTIC DIVISION produce spores, which then germinates under favorable conditions and grows into a new fungus. This new fungus cell is GENETICALLY IDENTICAL to the parent hyphae.
