Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Answer:
A) the lymphatic system only carries fluid away from tissues.
Explanation:
More differences between lymphatic system and circulatory system are:
• Circulatory system consists of a network of blood vessels through which blood is pumped by a “pump” called heart. In lymphatic system there is no such thing as a pump (only lymphatic vessels and lymph nodes)
• Lymph capillaries are closed on one side, so lymph does not circulate, but only drains to reach veins .
• Circulatory system has different role than lymphatic system: it tranports oxygen and other gases, nutrients and hormones, but also wastes that need to be excreted. On the other hand, lymphatic system has a role in immune system, fat and vitamin absorption and transportation.
