Answer:
Because the surface of a leave is nonpolar. I just did it!
Explanation:
The other answer is ridiculous! Please people don't answer (guess) if you haven't actually studied this before.
All the others ARE WRONG except for this one.
Just like when you step out of a swimming pool, why does the water roll off your body? Part of the answer is that your skin is made of cells that are covered in lipids. Lipids do not mix with water because water is made of polar molecules, and lipids are nonpolar molecules.
Ever heard the word hydrophobic? Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic. A leaf is nonpolar! Water is polar! They don't dissolve...
This is correct and true! But before submitting an answer make sure the question is the same one. Stay Safe!
Answer:
Thus, the common feature of the organelles within the list is that they are surrounded by a membrane. However, the membranes of each of the organelles are slightly different. For example, the nuclear membrane contains pores through which mRNA can travel to the cytoplasm in order for protein synthesis to occur.

Answer:
Body
Explanation:
Answer:
Systemic circulation is the movement of blood between the heart and therestofthebody.
Explanation:
The oxygenated blood will pass through the left ventricle to arteries then the capillaries of the body. After the oxygenated blood is distributed to all parts of the body, the now deoxygenated blood will return through a network of veins thus, to the right atrium of the heart.
A substance that affects the rate of a chemical reaction is typically referred to as a "catalyst."
A catalyst is a substance that increases the rate of a chemical reaction by providing an alternative reaction pathway with a lower activation energy. The catalyst itself is not consumed in the reaction and remains unchanged at the end of the reaction, making it available for use in subsequent reactions.
Catalysts work by providing an alternative mechanism for the reaction that has a lower energy barrier, allowing the reaction to occur more rapidly. They facilitate the formation of reaction intermediates and transition states, making it easier for the reactants to transform into products.
Catalysts are widely used in various chemical processes, both in laboratory settings and industrial applications, to speed up reactions, improve efficiency, and reduce the amount of energy needed for a reaction to occur. They play a crucial role in fields like chemistry, biochemistry, and industrial manufacturing, enhancing the production of essential materials and products.
