2. DNA is important to carry genes or genetic materials of the parents
Answer:
Option-D
Explanation:
The network of neurons which gets activated in the condition of stress that is fear or anger is known as Sympathetic nervous system.
During stress conditions, this system prepares the body physically and mentally either to fight or flight by controlling the production of hormones through activation of specific neuron network in the body. Mainly the adrenaline and norepinephrine which act and produces the response like increased heartbeat, sweating and other.
Thus, D)sympathetic is the correct answer.
Answer: b. nonreducing sugars which include among others raffinose, verbascose and stachyose
Explanation:
Phloem is defined as the vascular tissue which functions for the transport of sugars from source tissues, proteins and mRNAs throughout the plant.
Sugars present in phloem are non-reducing oligosaccherides which includes raffinose, verbascose and stachyose. Verbascose has three α-d-galactose molecules that are attached to sucrose; stachyose has two, and raffinose has one. The oligosaccharides are α-1, 6-galactosyl sucrose extensions (Suc). Those are present in plant phloems like Bignoniaceae, Oleaceae, Celastraceae, Myrtaceae, Verbenaceae and others.
These all functions for the transport of sugar in phloem sap and as storage sugars.
Hence, the correct option is b. nonreducing sugars which include among others raffinose, verbascose and stachyose
Answer: Terminal buttons
Explanation: Terminal buttons are the little rounded lump at the most extreme part of a lengthened fiber that cause to cover a wider range from the body of the cell to the terminal furthest parts, thereby conveying neural electrical impulse, which discharges distinct compounds named neurotransmitters. They virtually convert the pulse of electrical energy into chemical signals.
