We have 20 different amino acids in our bodies.
Answer:
Grana and stroma
Explanation:
Photosynthesis is the process by which plants make their organic food. This process occurs in the chloroplast of the cell. Grana and stroma are the two parts that are involved in photosynthesis.
Grana are stacks of thylakoid which increase the surface area for light absorption. It is the place where light-dependent reaction occurs. Stroma is the fluid that surrounds grana. It contains the enzyme which is required in photosynthesis. It is the place where light independent reaction occurs.
Stroma is the place where synthesis of organic material from carbon dioxide and water occurs. Therefore the correct answer is grana and stroma.
The answer is letter b, persistence. This characteristic is often describe as a way of how long it will be useful, just like how long will the pesticides could be useful in killing the things that it is useful for in which is in consistent with the given statement above.
Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
