The F factor straightly handover the donor chromosome in the cross. H takes roughly 90 minutes to transfer the chromosome. The big share of the F factor is last to be transmitted and the conjugation tube is very subtle so the probability for a thorough transfer is low. Consequently, when the bacterial strain attempts to inoculate an Hfr plasmid into an F- strain transversely the conjugation bridge through rolling circle replication, it is infrequently completed and typically breakdowns off before the F factor section is totally transferred.
Answer:
<em>they</em><em> </em><em>are</em><em> </em>climate, food supply, and actions of other organisms.
Answer:
Option B, The average number of food vacuoles formed in 30 min would decrease.
Explanation:
As we know ink solution act as a food source for the T vorax culture. The higher will is the amount of solution added, the higher will be the number of food vacuoles formed in a given time period.
Therefore, when 20 micro liter of ink solution is added instead of 100 micro liter of ink the food vacuole number will decrease.
Hence, option B is correct
Answer:
Parasympathetic nervous system
Explanation:
Parasympathetic nervous system together with sympathetic nervous system is part of the autonomic nervous system. The autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates smooth muscle and glands. Thus, it directly affects the function of internal organs and regulates functions such as the heart rate, digestion, respiratory rate, urination etc. This nervous system control is unconscious.
Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
I need point really sorry :/ksjsjs
