Answer:
(4) interact with other living organisms and interact with the physical environment.
Explanation:
Ecology is a branch of biology in which we study about relationship that is present between living organisms with their environment. Alexander von Humboldt is the first person who study the relationship between organisms and environment. He is also called father of ecology due to its contributions to this field. Ecology consist of 5 levels i. e. organism, population, community, ecosystem, and biosphere.
The answer is <span>chest x-ray

Sarcoidosis is a disease that caused by the appearance of multiple gr<span>anulomas, l</span>ump that made of inflammatory cells. Chest x-ray should show these lump easily, especially in the lungs because it is filled with air. I think MRI could also help to diagnose but x-ray should be easier and cheaper.
Answer:
Since the control is different, making an accurate prediction for this test is difficult.
Explanation:
Answer:
The presence of organelle DNA in mitochondria and chloroplast supports the theory that mitochondria and chloroplast originated as independent prokaryotic organism.
Explanation:
- The more well documented and generally accepted theory for the origin of eukaryotic organelles is Endosymbiotic Theory. (Margulis 1970).
- Recent evidences justify that organelles have originated from the endosymbiotic association of ingested aerobic and and photosynthetic prokaryote, the precursors of mitochondria and chloroplast respectively.
- Molecular data have played an important role in supporting the xenogenous origin rather than autogenous origin of organelles.
- The idea of independent existence of mitochondria and chloroplast are: they are replicators; they carry genetic information; they have protein synthesising machinery; they have ribosome of prokaryotic type.
- The prokaryotic or bacterial origin of mitochondria and chloroplast is supported by the fact like their DNA is simple ,closed and circular with single point of origin; DNA controls the synthesis of their rRNA and tRNA etc.; They have their own ribosome; antibiotic specificity.
