<span>Muscle cells and nerve cells (neurons) are two very different types of cells. While nerve cells are involved in the transmission of neural synapses (hence the name), myocytes contract to move the skeletal bones and move the body. Muscle cells can be smooth (visceral), cardiac, or skeletal.</span><span>Oct</span>

Answer:
Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary. Fertility treatments increase a woman's chance of becoming pregnant, although the treatment may not always work. On the other hand, because the treatment boosts the production of mature eggs, it increases the chance of twins or triplets.
Answer:
D
Explanation:
This is a typical monohybrid cross involving a single gene coding for seed shape in a plant. The allele for round seeds (R) is dominant over the allele for oval seeds (r) i.e. the round shape will mask the expression of the oval shape in a heterozygous state (Rr).
Hence, in a cross between two heterozygous parents (Rr), alleles on chromosomes will randomly separate into gametes according to Mendel's law of segregation to produce gametes with R and r allele each. When these alleles from male and female parent combine, four offsprings with RR, Rr, Rr and rr genotypes will be produced.
RR, Rr and Rr genotypes will be phenotypically round-seeded while rr will be phenotypically oval-seeded. Therefore, 3/4 × 100 = 75% of the offsprings will be round-seeded.
