This process is known as a involuntary reflex.
When a person has linked a neutral stimulus and an unconditioned stimulus so that now the neutral stimulus triggers the conditioned response, <u>acquisition</u> has occurred.
<u>Explanation:</u>
A trigger that in the beginning causes no specific answer other than attention concentration is understood as "a neutral stimulus". In operant conditioning the neutral stimulus becomes a conditioned stimulus when used in combined way with an unconditioned stimulus.
Now let us say, for instance, you need to take your child to the pediatrician for a shot. The pediatrist hits a buzzer before the shot to call her nurse to come in and help her conduct the vaccine. Here the buzzer's noise is the neutral stimulus, as it generates no reaction from the infant, but the child knows that.
Answer:
<em>The correct option is increased death rate</em>
Explanation:
Germ theory can be described as a scientific theory which depicts that microorganisms are the cause for many diseases which occur in humans, animals and plants. These microorganisms are known as pathogens or germs.
The formation of the germ theory led scientists to understand the pathogens involved in causing many diseases and hence scientists brought forward methods to kill the pathogens causing these diseases. Hence, the death rate did not increase after the germ theory.
Answer:
Each strand has a 3' end (unbound hydroxyl group) and a 5' end (hydroxyl group of deoxyribose sugar), the two strands run antiparallel to each other. (Ans. E)
Explanation:
DNA is known as Deoxyribonucleic acid. It is a complex organic molecular structure and present in all eukaryotes, prokaryotes and some viruses. For the transmission of inherited traits DNA codes genetic information.
It is a double-helix polymer consist of two spiral DNA strands fold around each other. Each strand of DNA is made up of a long chain of nucleotides. DNA's nucleotide consist phosphate group attached with deoxyribose sugar and nitrogenous bases two purine (adenine, guanine) and two pyrimidine (cytosine, thymine)
DNA have two distinct ends, one is 5'prime another is 3'prime. It means 5' and 3' carbon present on the sugar. 5' prime end consist phosphate group and 3' prime end consist hydroxyl group.
