There are 46 DNA molecules in each somatic cell.

46<span>Think carefully, now. How many DNA molecules are in each of your somatic cells? BEFORE replication, the normal amount (46 chromosomes)
AFTER replication and BEFORE division (made copies, but not divided up) so you have 92 DNA molecules, but 46 replicated chromosomes.

Part C
IrinaVladis [17]

Answer:

                     (i) 1 moles of C

                     (ii) 4.5 moles of C

Explanation:

                   The Chemical equation is as follow,

                                             A + 2 B  →  C

This chemical equation can be translated as;

(i) 1 mole of A reacts with 2 moles of B

(ii) 1 mole of A produces 1 mole of C

(iii) 2 moles of B reacts with 1 mole of A

(iv) 2 moles of B produces 1 mole of C

(v) 1 mole of C is produced by 1 mole of A and 2 moles of B

Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method.

As,

                        2 moles of B produced  =  1 mole of C

So,

                    2 moles of B will produce  =  X moles of C

Solving for X,

                      X =  2 moles × 1 mole / 2 moles

                      X =  1 moles of C

Note:

         In above problem the given moles were the same as that present in balance equation so incase if the moles are different from that of the equation then the method shown above can be used to solve it.

Lets try it for 9 moles of B:

As,

                        2 moles of B produced  =  1 mole of C

So,

                    9 moles of B will produce  =  X moles of C

Solving for X,

                      X =  9 moles × 1 mole / 2 moles

                      X =  4.5 moles of C

Xelga [282]
<h2>c.is the correct option</h2>

Explanation:

Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed

  • Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
  • Fungi absorb nutrients through following three ways:
  • By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
  • By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
  • Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food

In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed
