an animal can wound a tree by scratching away the bark. the tree can respond to the wound in many ways. the sap quickly covers the wound, and then the tree covers the wound with new growth. the diagram shows the cross section of a tree with a healed wound. what process worked most directly with a transport section to heal the wound?
Cellular reproduction is the process which worked most directly with a transport section to heal the wound.
What is Cellular reproduction?
This involves producing a copy of preexisting cells through the process of cell division known as mitosis.
The plant when injured yields multiple cells which covers it up and helps in the healing process.

Monosaccharides disaccharides and polysaccharides are examples of.
Answer:
Sugars
Explanation:
Saccharide is another term used to describe sugars. The prefixes (mono = one, di = two, poly = more than two) represent how many glucose molecules are present in the overall molecule. Glucose is the base structure of sugars. Furthermore, all saccharides (sugars) are carbohydrates.

growth cells?
Answer:
When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen (e.g. amino acids, DNA). Various fungi and prokaryotes then decompose the tissue and release inorganic nitrogen back into the ecosystem as ammonia in the process known as ammonification.

During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a(n)
During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
What is a tetrad?A tetrad is a structure formed during the prophase I stage of meiosis I whereby two homologous chromosomes pair together.
Meiosis occurs in two stages of division namely;
meiosis I meiosis IIIn meiosis I, homologous chromosomes are separated but are first paired during the prophase stage to form the tetrad or bivalent structure.
