Answer:
These strands are clones, however, due to their low genetic variability, the population becomes susceptible to diseases taking place in plants. Pando comprises grove of about 47000 trunks, these all are genetically similar that develops from a solitary underground species, Quaking aspen tree. Pando is an extremely large clone.
However, for the past some years, scientists are worried about Pando's health. For the past thousands of years, Pando was living in fine tune with the native wildlife population, but for the past some years, a shift in balance is noticed. As in the absence of the development of novel stems, nothing will be able to substitute the natural withering of the older ones, if this goes on, the death of Pando will take place.
Answer:
c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus
Explanation:
Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.
Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.
A. Mitosis is the correct answer.
DNA replication occurs in the two major types of cell division: mitosis and meiosis.
Mitosis is the splitting of a normal cell into two daughter cells and involves complete replication of the cells DNA to produce two identical copies. Meiosis is a specialised and more complex two-stage form of cellular division related to sex cells and involves DNA replication followed by an exchange of DNA material within/between the chromosomes to mix genes from both parents and produce daughter cells with half the number of chromosomes as the original parent cell. Animal sperms and eggs are examples of cells produced by meiosis and contain half the number of chromosomes as normal cells. When combined during fertilization the egg and sperm produce a cell with the full compliment of chromosomes.
Cytokinesis is a part of the cellular life cycle that is related specifically to the division of the cytoplasm (basically the "soup" of material inside the cell). It is part of the cellular division process but not specifically related to nuclear division (i.e. DNA replication).
Transcription relates to the production of RNA from DNA which is then used for protein synthesis. DNA is not replicated during the transcription process, rather, this is a separate process critical for the production of proteins by the cell.
The correct answer is Galen.
Galen considered anatomy as the foundation of medical knowledge, and he recurrently dichotomized and tested on the lower animals like pigs, sheep, and goats. Galen's supported dissection as the method to better the skills of surgery and research works.
In his work, he illustrated seven pairs of cranial nerves, observed the structural distinctions between the veins and arteries, and illustrated the valves of the heart.
