Answer:

Atrial contraction, or “atrial kick,” occurs at the end of diastole just before the closing of the mitral valve and after passive flow has reached the diastasis. Normally, greater than 75% of flow occurs during the passive portion of diastole.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants
Finger [1]

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.
