Answer:
Using agarose gel electrophoresis
Explanation:
Agarose gel electrophoresis is a method used in molecular biology to separate a mix of macromolecules such as DNA or proteins in a matrix of agarose. The separation is based on the size or charge of the molecules.
In this experiment, a sample of the PCR result is subjected to agarose gel electrophoresis to check if there are molecules of the same size of the beta-lactamase gene (present in the MH1 bacteria).
Answer:
Variation in gene leads to anatomical difference in the closely related species
Explanation:
Though some organisms are morphologically very different from each other, yet they can belong to same species group. It is because of shared genetic framework with minute changes.
For example – Human and chimpanzees have similar genes and share about 99 percent their genes with each other.
The variation in 1 % gene has led to visible anatomical differences such as varying lengths of arms, jaw structure and size etc.
The same is the case with six living species of mammals and their close relationship with dugongs and elephants
There are two main organs:
Kidney: purify blood from toxins, and harmful chemicals and excretes them from the body in the form of urine.
Liver: inactivates and filters toxins from the bloood and removes toxic substances that have been ingested, such as food additives, harmful minerals, toxic medications, excess hormones.
Answer:
Cell Structure. The cell structure comprises individual components with specific functions essential to carry out life's processes. These components include- cell wall, cell membrane, cytoplasm, nucleus, and cell organelles.
