Answer:
For muscle contraction to take place oxygen is needed. ... Oxygen allows the body to convert glucose into ATP more efficiently without creating a waste product.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. ... Whether you're exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP
ATP= Adenosine triphosphate

Answer:
Hypersensitive response
Explanation:
<em>The hypersensitive response is a defense mechanism developed by certain plants in response to the invasion of pathogens. </em>
<em>This mechanism features include the rapid death of cells and tissues surrounding the infection site so as to limit the invasion of the pathogens as pathogens require living cells in order to continue spreading.</em>
Answer:
Ok so i will try my best to describe the answers:
1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.
2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.
I hope this helps :D
Answer:
PLANT CELLS
Explanation:
plants use photosynthesis to get energy from the sun
Answer:a). mutated DNA strand
Explanation: Mutation is a permanent alteration or change in the nucleotide sequence of a DNA. When one or more wrong nucleotides are added to a growing strand of DNA during replication, the base pairs involved are said to be mismatched. These mismatches result in a mutated DNA strand instead of a complementary DNA strand. Normally, new DNA strands are complementary to the template strand in the sense that they are not the same in base composition and sequence rather, wherever adenine is found in the template strand, thymine occurs in the new strand and wherever guanine occurs in the template strand, cytosine occurs in the new strand.
