Living organisms are dependent on the soil in the following ways:
Soil plays an important role in a biogeochemical cycle, which is the main source of recycling nutrients from the atmosphere to soil and then to water.
All the plants (even aquatic), on which almost all the organisms depend directly or indirectly for food, grow in the soil, which provides them with nutrients and water for development.
Answer:
transports oxygen and carbon dioxide for the respiratory system.
Answer:
Option C
Explanation:
Let the allele for black color be "B"
and the allele for white color be "b"
Since after F1 generation all the offspring have black body with white speckles throughout their feathers.
Thus the allele for black and white show co dominance.
Genotype of parent after F1 generation would be Bb for speckled chickens
Cross between two specked adults will produce -
Bb x Bb
BB, Bb, Bb, bb
Out of four offspring 1 is black (BB), 1 is white (bb) and two are speckled (Bb)
Thus 50% of the offspring will be speckled, 25% will be black, and 25% will be white.
Option C is correct
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.
