I guess its DNA. DNA is the information code of the cell
Answer
A thick grouping of nerves that run down the back of the embryo
Explanation
The dorsal nerve cord is special embryonic characteristic of the ganglia. It is a hollow dorsal cord that is composed of a section of the exfoliated coagulant that forms a hollow tube unlike solid abdominal tubes in other animal species. It is located in the vertebrae of vertebrates.
Answer:
The correct answer is - organisms become specialized for individual tasks and communicate with each other.
Explanation:
The cells of a multicellular organism in order to maintain homeostasis which is a balance of various factors in an individual organism that helps in health. The cells of multicellular organisms help as they become specialized for particular functions.
These cells communicate with each other to regulating the homeostasis. Cells of the multicellular organism function as the team however they are interdependent.
Thus, the correct answer is- organisms become specialized for individual tasks and communicate with each other.
<span>Two checkpoints during the cell cycle that regulate cell division are right before S phase and M phase.
</span>Cell cycle checkpoints are control mechanisms <span>necessary for proper cell division. </span><span>In the cell cycle, there are two checkpoints: </span><span>the G1 checkpoint and the G2 checkpoint. <u>The G1 checkpoint is right before the S phase, and G2 checkpoint is right before the M phase.</u>
If something is wrong at the G1 checkpoint, the cell will not enter the cell cycle. It is important to be delayed before cell enters S phase where DNA replication commences.
The G2 checkpoint is a DNA damage checkpoint and if DNA is damaged, entering the cell cycle is delayed before mitosis (M phase).</span>
