The answer would be 50%.
Let's make a Punnett square for this:
Let F - Freckles
f - no freckles
Father: Ff
Mother: ff (She has no freckles, meaning she does not have the dominant allele)
F f
f Ff ff
f Ff ff
The count would then be 2/4 with freckles and 2/4 without freckles. So the percentage of would be 50% with freckles and 50% without freckles.
Answer:
The correct answer will be option-A
Explanation:
The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.
Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.
The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.
Thus, option-A is the correct answer.
The gravity of a black hole is so strong that not even light can escape. Even if a bright star is shining right next to a black hole, you cannot see the black hole. Instead of reflecting the light as other objects do, the black hole just swallows the starlight forever.
The railroad industry used coal to power steam engines, allowing businesses to build more factories for the production of goods.
Explanation:
It is also during the 1800s that the use of coal power enabled the smelting of iron and steel, in addition to the powering of steam engines. Coal and steam engines enabled the building of railroads to transport goods from industries.
Before the discovery of coal in the 1600s, energy was sourced from water wheels and the burning of biomass.
In addition. 1950s saw coal production decline to its lowest levels because it was overtaken by petroleum as the main source of energy.
