The correct sequence for the five phases in the systems development life cycle (sdlc) process is?
Sophie [7]

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.

Which organelles would create a basic protein that could be modified to move chromatids during metaphase?
bija089 [108]

The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.  

<u>Explanation:</u>

Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.  

The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.

A scientist conducts an experiment to test the effects of light on earthworm activity. Which is a variable in this experiment? l
777dan777 [17]

<span>I believe it is light, but this is kind of a confusing question. Technically there is a independent and dependent variable in the question. The variable being manipulated is light, and the earthwork activity depends on the light. </span>
