1. Shed: this is one structure essential in propagating young trees.

2. Location/Site: a place near a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.

3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.

4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees. Pots are used for germinating young trees while boxes and plots are used for raising seedlings.

Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.

Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.

Examples of matter and not
OleMash [197]
Well matter is basically any substance that has mass and takes up space. Example, you have a ball, or a table, or anything really. That is mass.
