Answer:
How are animals cloned? In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.
Explanation:
The answer is; D
Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.
<h2>Answer:</h2>
The correct option is C which is, "Deletion, Nondisjunction, Replication, and Transformation".
<h3>Explanation:</h3>
- Deletion is the process when one or more nucleotide is deleted from the genetic code in DNA.
- Nondisjunction is the failure to separate the homologous chromosomes during meiosis.
- While transformation is the addition of extra nucleotide in normal DNA.
- And rapid replication also leads to errors in DNA replication.
- All these processes lead to genetic abnormalities.
Answer:
The answer is B, I believe, because it states here that, "Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. ... The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction."
