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.
The answer is b since it is the most red and if you look at a compass, it is southwest
Answer:
False
Explanation:
The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.
They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix.
