The organisms homeostasis
An open circulatory system simply
means that the blood flows out of vessels and into the spaces or sinuses. Invertebrates,

sinuses, where the blood surrounds the tissues.
<span>Sclerenchyma cells are the strongest. They have a second cell wallwhich is hardened by lignin, making them very tough and durable.</span>
Answer:
mitochondria serve as the power house of a cell.
Anaerobic respiration.
<span>Anaerobic respiration is a type of cellular respiration BUT does not use oxygen (O2). It is used when there is not enough O2 for aerobic respiration.
</span><span>It can be summarised by the equation: glucose → lactic acid (+ energy released). However, it releases less energy than aerobic repspiration due to a lack of oxygen resulting in an INCOMPLETE breakdown of glucose.
