Answer:
A. The dominant factor, or allele, is for round seeds.
Explanation:
Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).
He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.
Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
Deletion is the correct choice
Down as there is mor gravity than air
Chem was fun last year XD
Anyway..
To find how many neutrons are in element x:
We take the mass number and subtract it with the atomic number
So, 75-22=53 neutrons...BOOM! :D
