The nucleus: a. directs cellular activity and stores hereditary information. b. modifies proteins that will be shipped elsewhere in the organism. c. synthesizes lipids and detoxifies molecules. d. digests and recycles cellular waste products and consumed materials. e. processes and packages proteins, lipids, and other molecules

A)The nucleus directs cellular activity and stores hereditary information.

Explanation:

The nucleus contains *chromatin and one or more denser, granular structures called nucleoli*. The *chromatin is a complex of DNA and histone and non histone protein, and it carries genetic/hereditary information of the cell*.* Nucleoli (sing. Nucleolus) are specialized parts of certain chromosomes that carry multiple copies of the DNA information to synthesize ribosomal RNA*. After transcription from the nuclear DNA, the RNA combines with several different proteins to form a ribosome, detaches from the nucleolus and passes through nuclear pores to the cytoplasm. The Nucleus also directs cellular activity.

In otherwords, Nucleus stores hereditary information and also directs cellular activity.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
