The correct sequence for the five phases in the systems development life cycle (SDLC) process is system analysis, conceptual design, physical design, implementation and conversion, and operations and maintenance
The study of life cycles is crucial to fostering children's global awareness and assisting them in grappling with difficult ideas like life, death, and birth. A life cycle approach can aid in our decision-making. It means that everyone has a responsibility and a part to play throughout the entire chain of a product's life cycle, from creation to disposal, taking into account all pertinent repercussions on the economy, the environment, and society.
A life cycle is a progression of stages that a living creature experiences. Life cycles are common to both plants and mammals. Diagrams are useful for illustrating the stages, which sometimes involve beginning as a seed, egg, or live birth, then growing up.

1.The nucleus is often considered to be the cell's control center.
(because it contains the DNA)
2.The cytoplasm consists of everything
inside the plasma membrane of the cell.
(actually it excludes the nucleus)
3.The plasma membrane forms
a boundary between the inside and outside of the cell. - it controls what can enter and what can't!
4.The cytoskeleton is essentially a "skeleton" inside the cell..
it maintains the form of the cell
5.The
rough endoplasmic reticulum is covered with
Ribosomes -they make the proteins!
6.Lysosomes
use enzymes to break down foreign matter and dead cells.
7.plant cells cells specifically have a cell wall, a large central
vacuole, and chloroplasts.-choloplasts are only found in plants!
In Eukaryotes, the DNA replication can start at several sites or places in the DNA molecule or DNA strand. The only important factor for DNA replication to start is that it starts at replication fork.
The replication of DNA is semi-conservative in nature because each strand acts as a template for synthesizing a new complementary strand of the double helix.
The new DNA is made with the help of the enzyme DNA polymerase which requires a primer for starting the DNA synthesis.
Replication occurs only at specific regions of DNA known as origin of replication and these are short sequences of nucleotides which are recognized by the enzyme for the replication.
The special enzymes or proteins recognize the specific sites and then binds to them. After binding, the DNA is opened up forming the replication forks which are two Y- shaped structures.
Cellular Respiration
Explanation:
For something to be living it doesn't need to be a cell or do photosynthesis. Cellular Respiration is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities
Answer:
apparently their gonna use that test and the homework and our attendance to give us a final grade
