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.
The tidal volume (TV) will be decreased greatly and it will be reduced to more than half of normal. In the event of complete obstruction of the right main bronchus; the whole right lung becomes a dead space wherein the right lung will not be ventilated. Ventilation is the exchange of gases between the atmosphere and the alveolus (which is primary site of gas exchange).
Answer:
This condition states that Xander's body temperature is normal. The human feels a little warm. It is due to the various metabolic activities that takes place inside human body.
Not everyone has the same body temperature. The normal body temperature is 38°C. But this can be a bit higher in case of children.
The temperature of the human does not stays same all day. It varies according to the work you do and the time of the day.
Explanation:
Controlled population growth.
Explanation:
US is a highly developed country and it has expansive infrastructure and highly mechanized agricultural equipments. So first option is not a choice. Second, access to chemical fertilizers and pesticides in a country with such advanced agriculture infrastructure is very easy. Third US is well known for using GM crops.
US does not have a controlled population growth because if not the birth rate then migration of people to US is a major concern for that country. Thus, this will be a correct choice for the given question.
