Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D

Which veterinary professionals design the veterinary curriculum? please help ​
Virty [35]

Answer:

Recent studies of the veterinary profession have established a need for training in various areas beyond those directed toward building competence and proficiency as a clinician. To address this need, a workshop was designed whose objective was to develop a detailed outline of a model curriculum that would encompass the skills, knowledge, aptitudes, and attitudes deemed essential for economic success in the veterinary profession. The model curriculum was created from comprehensive input provided by consultants and educators. Constraints for implementation of this curriculum are identified, and future directions are discussed.
