zavuch27 [327]

Answer:

Earliest- gametophyte dominance, sporophyte dependence

Middle- sporophyte dominance, gametophyte independence

Recent- sporophyte dominance, gametophyte dependence

Explanation:

The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores. The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.

In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.

Phenotype –

SsWw – Heterozygous Spotted skin and heterozygous wooled hair

ssWw - Homozygous non-spotted skin and heterozygous wooled hair

Ssww - Heterozygous Spotted skin and Homozygous non -wooled hair

ssww - Homozygous non-spotted skin and Homozygous non -wooled hair

Explanation:

Given -

Allele for spotted skin is "S"

Allele for non-spotted skin is "s"

Allele for Wooly hair is "W"

Allele for non-wooly hair is "w"

Allele "S" is dominant over "s"

And Allele "W" is dominant over "w"

Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

what is the force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second

vichka [17]

Answer:

The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.

Explanation:

According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
So, by performing the calculation, $\bold{\mathrm{F}=30 \times 0.4 \mathrm{N}=12 \mathrm{N}}$
12N force will move the boy along with the wheel chair.
