Explanation:
Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Answer:
MULTICELLULAR-means many cells whereas UNICELLULAR means one cell
Explanation:
Answer:
the gametophyte and sporophyte have the same genetic information but the gametophyte is haploid and sporophyte diploid in nature.
Explanation:
The heart shaped plant( gametophyte) produces male and female gametes which are haploid in nature. They fertilize forming an embryo. The embryo develops into a sporophyte which grows forming roots and leaves. This forms now the leafy fern plant. Both the gametophyte and sporophyte have the same genetic information but different genetic composition.
Answer:
The correct answers are:
- Purple flower is the dominant phenotype.
- The genotype of the original purple-flowered must be heterozygous dominant.
- The genotype of blue-colored plant must be homozygous recessive.
The cross between blue-flowered and purple-flowered plant resulted in the production of offspring with both types of phenotype. Thus, either one or both the parent plant must be heterozygous.
In addition, the selfing of blue-flowered plants resulted only in the production of blue-flowered plants. Hence, this must be homozygous in nature.
So, we can conclude that blue was homozygous and purple was hetrozygous.
We know that, trait which is expressed in heterozygous condition is termed as dominant. Hence, the trait of purple color must be dominant and that of blue color must be recessive.
Hence, the genotype of original blue-flowered plant must be homozygous recessive and that of purple-flowered plant must be heterozygous dominant.
