Introduction:
Different species of humans have been living from millions of years back. With every passing era some change in their structure and living has been predicted. From Homo habilis to Homo sapiens there are five species of human evolved from the beginning.
Answer to Problem 31A
Correct answer:
The correct answer is option (b).
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) the map represents the geographic range of Homo species.
Homo sapiens have been living from 195,000 years. They have a brain capacity of
Explanation for incorrect answer:
Option (a) Homo erectus are the early Homo sapiens that lived 1.8 million-400,000 years ago. The average brain of a Homo erectus have a capacity of
Option (c) Homo neanderthalensis Neanderthals are known as hominids from the Homo genus. They are the subspecies of modern Homo sapiens neanderthalensis.
Option (d) H. heidelbergensis is generally considered part of Homo. Sapiens. The name Homo heidelbergensis of the species was given because of the first discovery of skeleton near Heidelberg in Germany. It is an extinct subspecies of archaic humans.
The major area in the map represents the geographic range of Homo species.

- A farmer has noticed that his soybean plants produce more beans in some years than others. He claims to always apply the same amount of fertilizer to the plants, but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal average daily amount of water with which to irrigate. 1. State a question that addresses the farmer’s problem 2. Conduct online research on “soybean crop irrigation" and record a brief summary of the findings 3. Construct a testable hypothesis and record i 4. Design an experiment to test the hypothesis and describe the procedures, variables, and data to be collected 5. What is the purpose of a control group in an experiment? What would the control groups be for each of your designed experiments in this exercise? 6.
