Ligaments connect the ends of bones together in order to form a joint. Tendon - A tough, flexible band of fibrous connective tissue that connects muscles to bones. Joints - Structures that connect individual bones and may allow bones to move against each other to cause movement.
Explanation:
<span>c.)The product only has different physical properties than the reactants because a chemical reaction occurred.
This is because rust can behave differently than oxygen and iron. This is because a chemical reaction has happened- a chemical reaction is when a new product is formed. Rust can be change chemically and physically. </span>
Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop
Answer: Option D
<u>Explanation:</u>
Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.
Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
The correct option is ALL OF THESE.
Generally, three processes can lead to the removal of ions from solutions, these include;
1. The formation of an insoluble product, which is called precipitate.
2. The formation of either a non electrolyte or a weak electrolyte and
3. The formation of a gas product, which escapes from the solution.
Answer:
Genetic diversity is an advantage of sexual reproduction because it reduces the occurrence of unfavorable genetic traits and a variety of genes would lessen the chance of the extinction of a population due to environmental changes. The variation between a genetically diverse species will guarantee at least some of it survive when presented with different climates or challenges.
