I am not sure of the answer but I think it is d. Pesticide Use.
Almost all of the organisms in the PLANTAE kingdom are photosynthetic.
Answer: The balanced chemical equation is Pb(NO3)2 + 2KI ——-> 2KNO3 + PbI2
Explanation: A chemical equation is a condensed statement of fact about a chemical reaction which shows the kinds and number of atoms that took part in the reaction.
In writing chemical equations, the reactants are written on the left hand side of the equation with their correct formulae while the products are written on the right hand side of the equation with their correct formulae with an arrow in the middle showing the direction of the reaction.
In balancing a chemical reaction, the total mass of the reactants (number of atoms of reactants) must be equal to the total mass of the products (number of atoms of the products) formed because according to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction.
Pb(NO3)2 + 2KI ——-> 2KNO3 + PbI2
In the above equation, the number of atoms on both sides of the equation are equal.
Pb is 1 on both sides.
N is 2 on both sides.
O is 6 on both sides.
K is 2 on both sides while
I is 2 on both sides.
Answer:
Because of dark matter, gravitational interactions cause galaxies to develop.
Through dark energy, the universe is expanding at a faster and faster rate.
Explanation:
Which correctly relate dark matter and dark energy to the Big Bang theory? Select the two correct answers.
A. Through dark energy, the universe is expanding at a faster and faster rate.
B. Without dark energy, structures in the early universe would never have developed.
C. Because of dark matter, gravitational interactions cause galaxies to develop.
D. Dark energy is the source of 25 percent of the mass of the universe.
<u><em>Please don't use these for cheating they are for your help.</em></u>
B. is the correct answer because not all genes are actively coding,RNA is not code for protein synthesis, also DNA does not contain a number of segments that code for specific proteins.
