Answer: The statement which summarizes the law of segregation is as follows :
During the process of gamete formation, two different forms of a gene ( also called allele) segregate from one another in a random manner and each gamete thus formed, receives one copy of gene.
This is called the law of segregation. It was proposed by Gregor Mendel.
For example- The gene for plant height in pea exists in two forms which are T ( dominant allele- represents tall height ) and t ( recessive allele- represents dwarf height ). If a plant is heterozygous ( having different alleles Tt), it will give two different gametes ( T and t ) during gametogenesis.
These alleles are segregated in accordance with the law of segregation.
Lamarck was one of the first scientists to propose that species evolve by natural selection. Lyell was one of the first to say that Earth must be far older than most people believed. Lamarck's inheritance of acquired characteristics is has become a widely accepted scientific theory.
Answer:
C. hunting and gathering existence.
Explanation:
Paleolithic period, also called Old Stone Age, of human development is characterized by the use of rudimentary chipped stone tools although at that time, humans also used wood and bone tools.
During the Paleolithic Age, hominins grouped together in small societies such as bands existed by gathering plants, fishing, and hunting or scavenging wild animals. Other organic commodities were adapted for use as tools, including leather and vegetable fibers; however were discontinued due to rapid decomposition.
