Answer:Disadvantages: Adult stem cells have a determined cell type and cannot be changed into tissues that differ from the ones that they came from. This limits the cells by allowing them to be used only in procedures that involve the same type of tissue that they came from.
Explanation:
The correct answer is C. Translation.
The given figure is the scheme of the gene expression. It provides the flow of genetic information from a DNA sequence to a protein synthesis inside cells. This process of flow of genetic information from DNA to RNA is called transcription and the process of flow of genetic information from RNA to protein is called translation.
Thus in given figure label A is to be replaced by transcription and label B is to replace by translation.

Answer:</h2>
There two features which facilitates bird <u>to fly are presence of light and smooth feathers and light bones</u>.
<h2>
Explanation:</h2>
Birds are the only living creatures which has the ability to migrate from one place to another through flying. There are many physical features present in their body which facilitates them in flying.
<u>Among the two features and their role in flying are as follows: </u>
-
Light and smooth feathers: Wings are the organ which is involved in flying. It is composed of feathers which are very colorful and are light in weight and smooth in its appearance. This apart from reducing the body weight helps the bird to reduce the force and drag during flying.
- Light bones: The skeletal system of the birds is composed of light bone which are primarily hollow with air sacs. This accounts for less body weight while flying.
