Inprokaryotes how are binary fission and conjugation different?

Binary fission is a form of asexual reproduction in prokaryotes where a single cell divides into two identical cells. Conjugation is a process by which genetic material is transferred between two prokaryotic cells through a pilus, allowing for genetic variation but not cell division.


What is the difference between primary and secondary growth?

Primary growth is the lengthening of the stem and roots. All plant growth occurs by cell division and cell elongation. Cell division occurs primarily in regions of undifferentiated cells known as meristems. Cell division in the apical meristems and subsequent elongation and maturation of the new cells produces primary growth." on the other hand, secondary growth is the result of the activity of the vascular cambium. The latter is a meristem that divides to produce secondary xylem cells on the inside of the meristem (the adaxial side) and secondary phloem cells on the outside (the abaxial side). This growth increases the girth of the plant root or stem, rather than its length, hence the phrase "secondary thickening". As long as the vascular cambium continues to produce new cells, the stem or root will continue to grow in diameter. In woody plants, this process produces wood.


Explain the difference between sympathetic and parasympathetic reactions as they occur in the autonomic nervous system?

The sympathetic nervous system is most active when you are in an emergency, exercising, or an exciting or embarrassing situation. It is often referred to as the "fight-or-flight" system. It increases the heart rate, blood pressure, and blood glucose levels. It also dilates the bronchioles of the lungs, and dilates the blood vessels of the skeletal muscles. This nervous system enables the body to cope rapidly with situations. The parasympathetic nervous system is active when the body is resting. It is referred to as the "resting-and-digesting" system. It conserves your body's energy by slowing the heart rate. It also promotes digestion.sypmathetic is the "fight or flight" response and the parasympathetic is the "rest and digest" responses
