To be injured by an animal with poisonous spines, you must: be the aggressor and touch the animal first.
<h3>What is the use of spines in animals?</h3>
- Spines are hard, needle-like anatomical structures found in both vertebrate and invertebrate species.
- The spines of most spiny mammals are modified hairs, with a spongy center covered in a thick, hard layer of keratin and a sharp tip.
- Spines on an animal’s body help defend it.
- They can be irritating or painful, or difficult to swallow.
- Spines are also important tools for communication, shock absorption, and rain protection.
- Animals like porcupine shoot their spines (quills) for defense. Some spines can also pass through gloves.
- To prevent attacked by an animal with poisonous spines you must remain calm and observe your surroundings.

Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.

Explanation:
Liquid cooling is applied around the uranium rods to cool them. When this water is heated thanks to uranium, it produces water vapor.

Answer:
Centre of Gravity
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated[1]. Because it is a hypothetical point, the COG need not lie within the physical bounds of an object or person. One subjective way (there are objective measures) to approximate the COG of an object is to visualise it balancing on one finger.
Centre of Gravity in the Human Body
In the anatomical position, the COG lies approximately anterior to the second sacral vertebra. However, since human beings do not remain fixed in the anatomical position, the precise location of the COG changes constantly with every new position of the body and limbs. The bodily proportions of the individual will also affect the location of the COG.
