To write:
The principle of biology states that biology is an experimental science.
Introduction:
Scotch Heather (Calluna vulgaris) is native of Europe. It is an evergreen low-growing plant. It is a perennial shrub. Its height is about 2- inches. It has scale-like leaves which is small or short and set in opposite pairs. It is medium green in color. It belongs to Plantae (Kingdom),
Cross-leaved heath (Erica tetralix) is inhabitant to Western Europe. It is evergreen. It is a perennial shrub. It belongs to Plantae (Kingdom), Angiosperms (Clade), Ericales (Order), and Ericaceae (Family). It canraiseup to 0.3 meters (1 ft) tall. The flowers blossom in summer and autumn. It cannot grow up in the shadow. It prefers moist or wet soil. The plant can endure strong winds but not nautical exposure. The flower is of a pink-bell shape.
Purple moor grass (Molinia caerulea) is native to Europe. It is an ornamental grass. It is herbaceous and perennial bunchgrass. It belongs to Plantae (Kingdom), Angiosperms (Clade), Poales (Order), and Poaceae (Family). It grows up to 35 inches (95 cm) tall. The flower is purple. The level of water is medium to wet. The leaves are green in color, long flat, and have taper point.
Wavy hair grass (Deschampsia flexuosa) is found in Eurasia, Africa, North America, and South America. It belongs to Plantae (Kingdom), Angiosperms (Clade), Poales (Order), and Poaceae (Family). It is a species of bunchgrass. It grows up to 2 to 3 ft. The flower is purple to bronze in color. It grows at a medium water level. It can tolerate drought.

- Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group? A) A, B, C, and D B) C and D C) D, E, and F D) E, F, and Garrow_forward
