They are known as evolutionary biologists. Strictly speaking, anthropology is split up into a number of disciplines - physical (sometimes known as biological) anthropology is the study of evolution as it relates to human beings. Further to this, scientists who study evolution in the fossil record are known as evolutionary palaeobiologists or simply palaeobiologists.
Answer:
1. Jetty: Hard structure Built Perpendicular to the Shore, Can cause sand build-up on up drift side of the structure
2. Beach Nourishment: Brings in more sand to replace erosion.
3. Seawall: Hard structure that also provides flood protection, Prevents erosion by directing waves back to the ocean
Explanation:
Jetty is a hard and long structure that constructs of wood or concrete near the coastline, perpendicular to the shore that protects it from tides and currents which helps in preventing erosion. It can lead to build-up of sand on updrift side.
Beach nourishment is the process that replaces the sand or land that lost due to erosion and relensihsh the infrastructure of the coastline and protects the people and beach.
Seawall is also a hard provides protection from erosion by preventing the flood and pushes back the currents and tides to the ocean.
Not enough info, but I'd go with:
B) hydrogen peroxide
Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.
