The correct answer is: The nuclear envelope is continuous with the endoplasmic reticulum
The nuclear envelope or nuclear membrane is composed of two phospholipid bilayers (outer and inner) that surround the nucleus in the eukaryotic cell. The space between the outer and inner membranes is called the perinuclear space. The nuclear envelop has nuclear pores that are responsible for the transport between nucleus and cytoplasm (e.g. transport of mRNA).

Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
Antithrombin is a protein molecule that inactivates several enzymes of coagulation system. It is a glycoprotein produced by the liver consisting of 432 amino acids and three disulfide bonds. The antithrombin found in the blood and the cell lining blood vessels function to prevent unwanted formation of clot.
