Genetic variation helps populations adapt to a changing
timama [110]

Answer:

Please find the explanation below

Explanation:

Sexual reproduction is the kind of reproduction that requires two organisms (male and female) to form an offspring. The male organism produces gametes called SPERM while the female organism produces gametes called EGG. These two gametes come together in a process called FERTILIZATION to produce a zygote, which develops into an offspring.

In sexual reproduction, gametes are produced by organisms involved via a process called MEIOSIS. Meiosis, however, reduces the chromosome number of the gametes by half. However, one process unique to only meiosis and sexual reproduction is called CROSSING OVER.

Crossing over is the process whereby chromosome segments is exchanged between non-sister chromatids of homologous chromosome. This process causes a recombination of chromosomes (alleles) in such a way that the gametes will be genetically different from the parent organisms (genetic variation). According to this question, sexual reproduction leads to more genetic variation than asexual reproduction due to the process of CROSSING OVER that occurs in sexual reproduction.

To see how many atoms are in the chemical formula or element symbol, look at the subscript.
KengaRu [80]

Explanation:

To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms.

1. NaCl:

Na  = 1 atom

Cl = 1 atom

2. CO₂

C = 1 atom

O = 2 atom

3. O₂

O = 2 atoms

4. C₆H₁₂O₆

C = 6 atoms

H = 12 atoms

O = 6 atoms  

For the second part;

1. 2NaCl

Na = 2 atoms

Cl = 2 atoms

2. 3CO₂

C = 3 atoms

O = 6 atoms

3. 4O₂

O = 8 atoms

4. 2C₆H₁₂O₆

C = 12 atoms

H = 24 atoms

O = 12 atoms
