Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm. Bacteria can do this through several mechanisms.

Speculate as to how the information obtained from the sequencing of the human genome might be used to someday eliminate inborn e
Katena32 [7]

Answer:

Explanation:

Sequencing the human genome is the function of the human genome project with the goal of determining the base pairs/order of DNA nucleotides that make up human genome, and also identifying and mapping all of the genes of the human genome both from the physical level and its functions in molecular medicine. The benefits in this field could allow for better diagnosis of disease, early detection of certain diseases, and gene therapy and control systems for drugs.

Inborn errors of metabolism are rare genetic (inherited) disorders where the body cannot properly digest and turn food into energy through the normal pathway. The disorders are usually caused by mutations in specific enzymes that help in the break down of these foods.

Through the study of the human genome, sequences involved in these mutations giving rise to these disorders are identified and mapped to their variuos locations. This can help in the early diagnosis of the disorders and effective control system for drugs and gene therapy against these disorders.

During human fertilization, an egg and a sperm cell unite. which structures in these cells carry the genes that will be transfer
ArbitrLikvidat [17]

Answer: C. Chromosomes

When an egg and sperm cell unite, fertilization follows. The chromosomes carry the genes that will be transferred to the offspring. They have threadlike bodies that made up of DNA and protein that carries hereditary information, which is used to help a cell grow and reproduce.

Furthermore, humans have 46 chromosomes and 23 in each sex cell and they are found in the nucleus of a cell.
