Answer:
A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
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.
Answer:
A cell cycle is a series of events that take place in a cell as it grows and divided. ... The cell then leaves interphase, undergoes mitosis, and complete its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle. so the awnser is b as in bee
Explanation:
Okay First lets take a dee breath now Step-By-Step
first we think about what the cell cycle is good question!
come up with a good explaining and why is that the awnser" then write facts down and you should have your awnser
