Answers

Answer 1
Answer: Q1. The answer is c. a mechanism of evolution.

Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution. 


Q2. The answer is c. interactions between individuals.

Organisms interact with other organisms or abiotic factors in some system. The interaction between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.

Answers

I believe the correct answer is option D. Corinthian is not one of the three main periods of Greek sculpture. Instead, it is Archaic, Classical and Hellenistic that are the main periods. Corinthian is the  last developed of the three principal classical orders of ancient Greek and Roman architecture. 

Option D i.e Corinthian is the correct answer.

The three main periods of Greek sculpture are :

1. The Archaic Period (c.650-500 BCE) : In this period monumental marble sculpture was developed.

2.  The Classical Period (c.500-323 BCE) : During this period, the Greek sculpture was at its peak.

3. The Hellenistic Period (c.323-27 BCE) : The "Greek" style of 3-D art was practiced.

What are the three main parts of the geosphere?.

Answers

Planet earth is generally thought of a composed of the atmosphere, the hydrosphere, the lithosphere and the biosphere. The geosphere is often used to mean the same thing as lithosphere - rocks and stones. If this is how you are using the word, then the geosphere consists of the crust, the mantle and the core.

Final answer:

The three main parts of the geosphere are the crust, mantle, and core.

Explanation:

The three main parts of the geosphere are the crust, mantle, and core. The crust is the outer layer of the Earth and consists of oceanic basalt and continental granite. The mantle is the largest part of the Earth's interior, lying between the crust and the core. It is more or less solid but can deform and flow slowly. The core is the central part of the planet and consists of higher density material.
