Answer:
This question lacks options; the options are:
A) Artificial selection
B) Stabilizing selection
C) Disruptive selection
D) Directional selection
The answer is D) Directional selection
Explanation:
Changes in the environmenal condition affects the distribution of organisms phenotypes. Via this change, organisms with certain traits are naturally selected. The types of natural selection are; stabilizing, disruptive and directional.
Based on the description of the selection in this question, the type of selection is DIRECTIONAL. Directional mutation is that in which one of the two extreme phenotypes in a population is selected against while the other is favored by the occurrence of a natural environmental hazard. The distribution gradually shifts to favour one extreme over the other until the other unselected extreme gets extincted.
This is the case regarding a population of finches affected by drought caused by flood causing all their food source to disappear leaving only ant hills that certain finches with thin beaks can access. This environmental change favorably selects one extreme phenotype (finches with long thin beaks). Hence, a type of DIRECTIONAL selection

Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.
Answer:
36
Explanation:
A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
