Answer:
FALSE
Explanation:
Papillary muscles are found in the bottom chambers of the heart and attaches to the tricuspid and bicuspid valve through tendons to facilitate blood flow during systole. It also prevent prolapse. These muscles contract before the contraction of ventricular muscles (or before the contraction of ventricles) by pulling chordae tendinae till the ventricles are relaxed. This helps in preparing the valves for high ventricular pressure
Hence, the given statement is false
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
It’s community cause in a community people are together and interact with each other
In an animal cell, DNA is found in the greatest concentration in the Nucleus.
Answer:
When the energy is absorbed in a chemical reaction, we can say that this is an endothermic reaction.
Explanation:
An endothermic reaction is a chemical reaction that absorbs energy instead of releasing energy, like exothermic reactions.
To be considered an endothermic reaction, the chemical reaction must have a low energy reagent and for that reason, they need to absorb energy so that there is a rearrangement of the reactant molecules, forming products with high energy.
