<u>Answer</u>: 2.soil minerals, oxygen, rain, sunlight.
<u>Explanation</u>:
- <em>Abiotic factors </em>are the non-living and physical factors of the environment. For example, rocks, wind, soil etc.
- The<em> biotic factors </em>are the living components of the environment for example plants, animals etc.
- Since <em>soil minerals, oxygen, sunlight, and rain are all non-living components they all fall under the category of abiotic factors. </em>
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation.
The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>
Answer:
CRCR × CWCW
Explanation:
Flower color in snapdragons exhibits incomplete dominance wherein the heterozygous genotype exhibits the blend phenotype. To have all the pink-flowered progeny, all the progeny should have CRCW genotype and must obtain CR allele from one parent and CW from the other.
Among the given options, parent genotype "CRCR × CWCW" will give all the pink-flowered progeny. The parent plant with genotype CRCR would produce all the gametes with "CR" alleles while the parent with genotype "CWCW" would produce all the gametes with the "CW" allele. The random fusion of these gametes from the two parents would give all pink-flowered progeny with genotype "CRCW".
