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.
It reduces the crop’s ability to develop disease resistance
True
Explanation:
Photosynthesis is basically a simple and natural process. Photosynthesis is defined as the process whereby green plants manufacture their food in the presence of sunlight, carbon dioxide and water.
- The process of photosynthesis is vital to all life.
- Through photosynthesis light energy from the sun is transformed into chemical energy.
- The food manufactured by plants is consumed by organisms higher up in the trophic level.
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
photosynthesis equation.
- The product of photosynthesis is glucose and water.

Answer:
Interspecific competition is when different animals that live in the same geographic area (sympatric species) compete for the same set of resources, mostly food and space. ... This occurs when a species' survival or reproduction is suppressed because of the presence of a staunch competitor.
DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.
