Hormones are the intercellular signal discharged into the blood by specific cells, they travel some distance in order to reach their target tissues and to perform other specific activities. Autocrine refers to the intercellular signals, which are discharged by the cells in a local area and affects the activity of the similar type of cell from which it was discharged.
Paracrine refers to the intercellular signals, which are discharged by the cells and influences other kinds of cells locally without being transported into the blood. Pheromones refer to the intercellular signals secreted into the surrounding and change the behavior and physiology of other individuals.
Neurohormones or neurotransmitters are the intercellular signals produced by the neurons. Of the mentioned intercellular signals, the "e" signifies neurotransmitter.
Answer:
a. Hereditary genetics = 1 and 2
b. Population genetics = 3
c. Molecular genetics = 4 and 5
Explanation:
Genetics is a discipline that studies the transmission of heritable traits from parents to offspring. Population genetics is a discipline that analyzes genetic and allele frequencies in natural populations, as well as their changes in evolutionary processes. Finally, molecular genetics is a research field that studies the structure of the DNA molecule, its replication and the development of genetic engineering technologies associated with the manipulation of genetic information.
Not including the variety generated by crossing over, 16
Answer:
Option D, strive for 20-30 minutes for continuous aerobic exercise daily
Explanation:
Peripheral Artery Disease (PAD) is caused by development of plaque in the arteries which is commonly termed as atherosclerosis. The plaque reduces or limits the flow of blood which can leads to failure of organs such as kidney, may cause foot or leg amputations, and in severe cases PAD may cause heart attack, cardiac arrest or stroke. In general, a person with PAD is recommended to do treadmill walking as it allows the better flow of blood which was earlier restricted by the plaque
Hence, option D is correct
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.
