Hope this helped :)
Sporophyte generation - It is found in both seed and seedless plant. Dominant phase of the life cycle of the seedless plants is diploid sporophyte while in seed plant male and female gametes fuses to produces a diploid zygote which develops into a sporophyte.
Pollination - It occurs in seed plants only
Sporophyte contains male and female reproductive structures - It is found in both seed and seedless plant.
Single fertilization - It occurs in both seed and seedless plant
Sperm cells transported by water to egg cells - seedless plant only
Answer:
- "Mid oceanic ridge"
Explanation:
<em> Mid-ocean ridges are formed by divergent plate boundaries in the ocean. This is where upwelling magma creates new seabed. A diverging plate boundary occurs when two plates move away from one other. Magma rises from deep beneath the Earth and erupts along these boundaries, forming new crust on the lithosphere. The majority of divergent plate borders are undersea, forming submerged mountain ranges known as oceanic spreading ridges. </em>

Answer:
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
Explanation:
Let the allele for dark brown pigment be represented by "B"
And the let allele for white (no pigment) be represented by "b"
Due to incomplete dominance, the phenotype of heterozygous species would be "light tan"
Genotype of heterozygous female - Bb
Genotype of heterozygous male - Bb
Bb * Bb
BB, Bb, Bb, bb
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
It is called the Epidermis. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
