Answer:
a. All of the answers are correct.
Explanation:
During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.
For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.
After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.
Bc they create raw materials which converts directly to energy
<span>The lymphatic system is considered as the subsystem of the circulatory
system that is composed of networks of vessels, tissues and organs in vertebrates.
Its anatomy is composed of lymph nodes and lymphatic vessels which connect the
other parts systematically. A picture of the lymphatic system is attached below.</span>
The cells of the CNS are called neurons. They secrete neurotransmitters.
<span>The correct answer is d. increase the rate of breathing.</span>
<span>
Peripheral chemoreceptors (the carotid and aortic bodies) can sense hypercapnia (high CO2) and then they send a signal to the breathing centre. Breathing centre is in medulla oblongata which regulates breathing movements. When CO2 reaches a certain level, a signal is sent to trigger an inhalation and the rate of breathing is increased.</span>
