Answer:
Biodiversity is the variety of different species of organisms on Earth, or within an ecosystem. High biodiversity is important. It make sure that ecosystems are stable becuase different species depend on each other for things like shelter and fodd. Different species can also help to maintain the right physical environment for each other (e.g. the acidity of the soil.)
Explanation:
C.) Each of the organs is made from individual cells.
All of the organs have different functions.... very different.
Humans can survive without some of our organs, such as a kidney, gall bladder, etc.
And only a certain number of organs can make up the respiratory system.
Answer:nucleic acids, poorly conserved
Explanation: conservative can occurs in coding and non coding nucleic acid sequences. In coding Amino sequence acid and nucleic to maintain the structure of a certain protein. They are usually replaced by biochemistry similarity. DNA is conservated with replication. The new strands are complimentary to the original template which makes it identical to the other template.
Answer:
Golgi apparatus and extracellular matrix
Explanation:
The Golgi complex lies at the heart of the secretory pathway and is responsible for modifying proteins and lipids, as well as sorting newly synthesized molecules to their correct destination. As a consequence of these important roles, any changes in its proteome can negatively affect its function and in turn lead to disease.
Disruption of specific transport steps between the endoplasmic reticulum (ER), Golgi complex, endosomal-lysosomal system and the plasma membrane all can have dramatic consequences on the cell, and increasingly defects in the molecular machinery regulating membrane traffic are being linked to hereditary diseases.
Any changes to the proteome of the Golgi complex would affect its homeostasis and consequently the flux of proteins trafficking through it.
One possible consequence of mutations in Golgi complex proteins is that they cause gross changes in the morphology of the entire organelle and protein mislocalization, which together result in functional problems such as impairment of glycosylation.
Genetic studies of humans and mice continue to highlight the nonredundant mechanical role of components in complexes that anchor cells to extracellular matrices. At the same time, recent data provide exciting insights into, critical roles of transcription factors in regulating differentiation and function of matrix-producing cells.
Answer:
Option-B
Explanation:
DNase I is an enzyme which acts on the DNA in its single-stranded, double-stranded and chromatin form.
The DNase acting sites on the DNA is known as the DNA I hypersensitive site. The DNase I hypersensitive site allows the DNase I to act as the condensed form becomes less condensed. This mechanism can be associated with the transcription as, during transcription, the DNA becomes less condensed and is open to DNase I enzyme.
Thus, Option-B is correct.
