<span>If the circulatory system malfunctions, all other systems are affected. In living, this system is vital for all organisms. Muscles and organs will not get the necessary nutrients and energy to perform their tasks if even one of the systems are affected. In this case as well, the relation between circulatory and digestive system is crucial. Digestive system can no longer break down food in order to convert them to energy, and tissues and organs can no longer absorb these nutrients to the body, as all cycles in the body are interconnected, the body will deteriorate resulting to cell and tissue death.</span>
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.
Hope this helps (:

Answer:
During evolution, plants have acquired a vascular system, which has greatly contributed to the success of land plants. The vascular system allows plants to rapidly transport water and nutrients over long distances between roots, growing deeply in soil, and shoots, growing upward toward the sun.
Answer:
each nucleotide triplet (called a codon) specifies a particular amino acid. Thus, a nucleotide sequence in the DNA specifies a protein provided that a messenger RNA molecule is produced from that DNA sequence. Each region of the DNA sequence specifying a protein in this way is called a gene.
Answer:
Tendon sheaths <u>act as friction-reducing structures.</u>
Explanation:
Tendon sheaths are fibrous tissue that is around tendons to protect and make the movements of these smoother. For example, they reduce the friction of the flexors and extensors tendons of the hand. These are tendons that we constantly use to open and close our hands when we want to grab objects. Without the sheath, the tendons will not move easily, and due to the excessive use, there can be inflammation.
The sheats have two layers, one internal, which is a synovial one that produces synovial fluid to lubricate the tendon, and the external, which is a fibrous layer.
