What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.

Answers

Answer: Fearful and worried posture

Explanation:

Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.

When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to  make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).

All these tell that a dog is scared and worried or feeling tense.

Answer:

Defensive Threat Posture

Explanation:

Whale eye (whites of eyes showing)

Tail down or fully tucked

Piloerection

Ears back or flatten against head

Pupils dilated

Corners of mouth pulled back

Body lowered

Body leaning backward

A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?

Answers

Answer:

Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.
