The </span>holotype<span> of the species was tall, 1.8 m (6 ft) and more muscular than modern humans.</span>
Answer:
Nervous and endocrine
Explanation:
The nervous system triggers the endocrine system to produce hormones that cause fight or flight
The parent cell divides into two "daughter" cells. This will repeat over and over, and this is what we define as the cell cycle!
Fun Fact: Each stage of the cell cycle, such as G1 (Growth/Gap 1), Synthesis/ Stage, then G2/ Gap 2 stage, then following mitosis, has their own checkpoint! These checkpoints review/ revise what the cell has done during the stage.
Me too, I disagree to what he says
I think it’s d because it should take a while to accomplish a long term goal
