Acetylcholine is the neurotransmitter important for muscle contraction as it binds to receptors on the membranes of muscles and cause the membranes to open channels for movement of calcium and sodium ions
Answer:They get there energy by autotrophs
Explanation:
They get there energy by autotrophs
I would say option A, when a drug kills most of the bacteria the ones left to breed are those that have a natural resistance to the drug.
Cross pollination is the transfer of pollen of different species to stigma of different species of plants.
Cross pollination results in healthy, viable and diverse plants.
Mendel observed that traits could either be dominant or recessive.
Blended traits or incomplete dominance is the condition in which dominant allele could not produce its trait alone instead blending with recessive allele takes place giving new phenotype to progeny.
Explanation:
In cross pollination pollen transfer takes place from anthers to stigma. In Mendelian genetics the anthers of the plant was removed because it has both male and female parts on same plant so that self pollination does not take place.
The importance of cross pollination is that it creates diversity in the plant species since the traits having different alleles are combined to form the progeny plant. The offspring are healthier and high quality seeds are found.
Mendel observed that traits are either dominant or recessive in general. It was observed that when homozygous parents were crossed, the progeny in F1 generation always had dominant trait. The recessive trait only appeared when F1 generation offspring were self pollinate.
Blended traits or incomplete dominance appear when alleles get blended and exhibit the traits in phenotype. The phenotype appeared will not be matching with either parents.
The example is a white coloured flower is crossed with red colour flower the resultant colour of the flower is pink. It shows that dominant allele red is not completely dominant and gets blended with white colour.
Dopamine
On a biochemical level, cocaine blocks the reabsorption of the neurotransmitter dopamine.
Dopamine is a neurotransmitter (chemical) released by nerve cells in the body to transmit information from one neuron to another. Dopamine performs various important roles in the brain and body. Cocaine, which is a drug of abuse, blocks the reabsorption of dopamine. Cocaine acts by binding to the dopamine transporter, and stops the removal of dopamine from the synapse. Dopamine then increase in the synapse to form an amplified signal to the receiving nerve cells. This result in euphoria (feeling of intense excitement) experienced immediately after administering the drug.
