Answer: neurotransmitters
Explanation:
The neurotransmitters are the chemicals which are released at the synaptic cleft or synapse present between the two neurons. These are the chemical messengers which carries the signals from one neuron to other and helps in transmission of the information. The chemical molecules of the neurotransmitters usually diffuse across the synaptic cleft and they bind to the receptors of the postsynaptic cells.
Heat detection is needed for breeding.There is a system called timed breeding or the appointment breeding which is made so that the onset of heat and ovulation are induced for an animal to be inseminated at the right time. These then will help the breeder as well as the owner.
Answer:
The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.
Explanation:
Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.
There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.
According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.
Alexander Solzhenitsyn believed that writers and artists can stop falsehoods/lies. Alexander won the Nobel prize in 1970 for Nobel Lecture.
