A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

The step in translation initiation that is unique to the eukaryotes is:
<span>formation of the preinitiation complex ribosome assembly
</span>
Here are the processes involved in the Translation Initiation of Eukaryotes
1) 5'cap is used to position the mRNA on the 40S ribosomal subunit
2) ribosome scans down the mRNA looking for an AUG.
3) There is an initiator methionine-tRNA
4) The initiating AUG codon is often within a consensus sequence called the Kozak sequence (5'-ACCAUGG-3')
5) After binding the cap, ribosomes scan down the mRNA until the Kozak sequence is reached and translation begins
<span>6)The poly (A) tail and 5'-cap binding proteins help the initiation complex form

Answer:
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks.
Explanation:
To understand more about working of enzyme and its activation energy lets consider few points:
• In biochemical processes, molecules require energy in order to start a reaction. For example, molecules need to have some kinetic energy, or velocity, to collide with other molecules to initiate a reaction. If the collisions don't happen often or don't have enough kinetic energy, no reaction will take place. The energy required to start a reaction is called the activation energy.
• Reactants and products have specific energies. In order to transform the reactants into products, the reactants would have to go through a transition state which is usually higher in energy.
• In this graph we see the plot of energy versus the progress of a reaction. Reactants have higher energy than products. The energy of the reactants increase and then decrease to the final product energy. The highest point in the curve represents the energy of the intermediate state in the reaction. The energy required to achieve the intermediate state is the activation energy of the reaction.
Thus, we conclude that enzyme requires certain amount of energy to complete the reaction and that energy is known as activation energy for the reaction.

hormones can stimulate cell regulators to increase cell reproduction. Thus option C is correct.
<h3>what are the role of hormones in reproduction ?</h3>
Hormones are the chemical messengers produced by the endocrine cells and it move through the blood, act on target cells.
The two most important reproductive hormones are estrogen in female and testosterone in male.
Estrogen induce the eggs development and maturation process in adult female and released during regular intervals of menstrual cycle.
Testosterone in male responsible for male gamete production.
Other hormones involved, such as Follicle stimulating hormone (FSH), Luteinising hormone (LH).
Thus option C is correct.
