The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
By studying a particular species .
Answer:
RrYy (F1 generation)
Explanation:
This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.
According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.
Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.
In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.
Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
The level of succession which involves a small snake is found eating a cricket in a grassland is a Secondary succession.
<h3>What is Secondary succession?</h3>
This is the type of succession which involves an area previously occupied by living things is disturbed or disrupted.
The grassland area has been occupied with living things already which makes it a secondary succession.
