The FedEx of the cell are the vesicles.
Vesicles are the structures in which many cell materials are packed and transported. Vesicles are cellular organelles that are composed of a lipid bilayer and they function as cellular envelopes to transport cell materials from one place to another inside the cell.
An example of one material is protein. After a particular protein has been synthesized in the ribosomes of the cell, it is packaged in a vesicle called a transport vesicle. The vesicle carries this package to the Golgi apparatus for final tweaking after which it is again repacked in a new vesicle which transports it to its required destination in the cell.

Answer:
RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule.
Explanation:
please mark me as brainliest
Answer: Hypothalamus
The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.
Explanation:
Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:
- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics
- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.
Thus, hypothalamus plays important role in puberty
Answer:
Option B, a generation
Explanation:
A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family
Such as transmission of any genetic diseases from one generation to the other.
Hence, option B is correct
