Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.
It is the order of classification which consists of
Kingdom-Phylum-class-order-family-genus-species.
Please mark me as brainliest.
Answer:
A. The brain could not monitor the expansion and relaxation of the aorta.
Explanation:
Baroreceptors are sensors present in the aortic arch and in the carotid sinus which are responsible to sense the blood pressure and brain the communicate this information to central nervous system for maintaining the blood pressure.
When baroreceptors stopped working or uring baroreceptor dysfunction, the blood pressure increases but returns to normal after an hour. In baroreceptor dysfunction, brain will be unable to monitor the expansion and relaxation of the aorta and results in the increase blood pressure. Soon the baroreflex occurs and helps in returning the pressure toward a normal level.
Hence, the correct option is A.
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.
its thermometer
A THERMOMETER measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury.
