Answer:
the type of reproduction in which only a single parent is involved is called assexual reproduction
Explanation:
The correct statements are as follows:
1. Reactants must collide, with proper orientations, with the energy greater than or equal to the activation energy for a reaction to take place. It is a correct statement, as to undergo a chemical reaction, the atoms should exhibit proper orientations and enough energy to reach the activation energy.
2. Increasing the concentration of a reactant increases the number of collisions, and the reaction goes faster. The mentioned statement is true, as when increasing the concentration of reactants, there should be more reactants. Thus, the collision will be more that makes the reaction to go faster.
3. The energy of a collision between the molecules or atoms must be greater than the activation energy to break the bonds. The given statement is true, as, with the increase in activation energy, the reaction will get slower. Thus, the energy of the reactants is greater in comparison to the activation energy, and then the reaction is faster to break the bond.
4. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes very slowly. The given statement is true, as when the temperature decreases, the kinetic energy that is required to dissociate the bond, also decreases. This undergoes a slow reaction.

Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.

Answer:
4.952 × 10^28 atoms
Explanation:
1. Atoms in one molecule of glucose
The formula for glucose is C6H12O6.
In one molecule of glucose there are
6 + 12 + 6 = 24 atoms
2. Molecules of glucose
Molecules = 6853 mol × (6.022 × 10^23 molecules/1 mol)
= 4.1269 × 10^27 molecules
3. Atoms
Atoms = 4.1269 × 10^27 molecules × (12 atoms/1 molecule)
= 4.952 × 10^28 atoms
There are 4.952 × 10^28 atoms in 6853 mol of glucose
