Describe the changes that have occurred to the nucleolus and nuclear membrane from interphase to prophase?
During interphase, the nucleolus is visible and active in producing ribosomes, while the nuclear membrane is intact, surrounding the nucleus. As the cell enters prophase, the nucleolus begins to disappear as the ribosomal RNA is dispersed throughout the nucleus. The nuclear membrane also breaks down, allowing the chromosomes to condense and become visible.
What else can I help you with?
Which period is when mitochondria and other organelles are manufactured?
Mitochondria and other organelles are manufactured during the interphase stage of the cell cycle, specifically during the G1 (gap 1) phase when cells are growing and preparing for DNA replication in the S phase. Organelles are synthesized to ensure that each daughter cell receives the necessary components during cell division.
What is the correct order of stages which must have occurred in evolutionary history for complex cells to have evolved?
The general order of stages in the evolution of complex cells is: formation of simple prokaryotic cells, development of internal membrane structures, acquisition of a symbiotic relationship with mitochondria, emergence of a nucleus and other organelles, and finally diversification and specialization of cell types in multicellular organisms.
What type of mutation occurred in the strand of DNA?
A point mutation occurred in the DNA strand. This is a change in a single nucleotide base, such as a substitution, insertion, or deletion.
Final preparation for cell division are made during the life cycle subphase called?
G2 phase. During the G2 phase of the cell cycle, the cell undergoes final preparations before entering mitosis, such as checking for DNA damage and ensuring that DNA replication has occurred accurately. This phase allows the cell to ensure that everything is ready for successful cell division.
The hypothesis that evolution occurred slowly but steadily is called?
The hypothesis that evolution occurred slowly but steadily is called gradualism. This theory suggests that small, incremental changes accumulated over long periods of time to result in the diversity of life we see today.
Ribosomes are produces by the?
Ribosomes produce during the process of translation. This process occurred in the nucleous of the cell.
Describe one major event that occurred during the Presidency. for Calvin Coolidge?
qweq
What is the first event that occurred when a virus infects the host cell?
The virus attaches to the host cells membrane.
What has occurred at the end of Prophase?
At the end of prophase all of the chromosomes(chromatids joined at the centromere) are now floating around the cells and the spindle fibers are formed. Then you go into Metaphase where the chromosomes line up in the center of the call and the centromeres attach to the spindle fibers. Hope that helped!:)

What does it mean by 'describe 5 major plot occurrences' in the good earth?
It means to describe the 5 most important events that occurred in the good earth. (Tell why it's significant.) Hope that helps!
When do you use I had versus I have had?
I had is used when describing an event occurred in the past and stopped there. I have had is to describe an action that was completed in the past but have continued into the present. Rex

Is it legal for a repossessing agent of a vehicle to physically threaten or restrain the owner?
