Producers (PLANTS) convert solar energy into chemical energy(energy-stored in carbohydrate) by photosynthesis , this food prepared or the plant is eaten by animals which are eaten by other animals, in this way energy is being transfered and it all started by the producers
These are the main factors:
• the amount of current flowing through the body
• the path of the current through the body
• the length of time the body is in the circuit
• the voltage of the current
• the presence of moisture in the environment
• the phase of the heart cycle when the shock occurs
• the general health of the person prior to the shock
• how quickly the person is treated.
Answer:
The mRNA for an Alzheimer-related gene is 2400 nucleotides long when isolated from neurons, but 2900 nucleotides long when isolated from glial cells. Genomic DNA isolated from the two cell types show the identical nucleotide sequence. the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Explanation:
A controlled process during gene expression that results in a single gene coding for multiple proteins is referred to as alternative splicing.
During this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene.
Thus, the mechanisms that best accounts for the difference in the sizes of the mRNAs is the alternative slicing mechanism.
Answer:
Semi-Conservative
Explanation:
After DNA replication, the parental DNA molecule contains two original DNA strands while the daughter molecule is composed of two newly synthesized strands. In this model, the two DNA strands in the parental molecule separate from each other and serve as templates for the synthesis of daughter strands.
