In angiosperms pollen grains are produced in anthers
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.
BMI is used mostly to determine the fat ratio compared to your body weight and height.
Answer:
B is the correct answer.
Explanation:
Law of conservation of mass states that the mass of an object never changes with time. This means that during a chemical reaction mass of reactants always remains the same even after the formation of products.
We can conclude that the law of conservation of matter states that during a chemical reaction, the amount of matter does not change
