According to Joel Cohen, head of the laboratory of populations at Rockefeller University, the earth's carrying capacity for human populations depends upon:
A. reducing meat consumption.
B. eliminating social barriers to innovation.
C. individual choices concerning consumption patterns.
D. freshwater supplies
is it C
__________ now rivals tuberculosis as the world’s most deadly infectious disease.
Influenza
Hepatitis
AIDS
Cancer
is it AIDS
I think there's a better answer for your first question.
I agree with your second answer.
the only one makes sense is B for #1
Which do people need most? Meat or water?
To determine the correct answers to these questions, we can analyze the provided options and their relevancy to the statements.
For the first question about the earth's carrying capacity for human populations, Joel Cohen identified several factors. Let's review each option:
A. Reducing meat consumption: While reducing meat consumption is a valid consideration for sustainable agriculture and environmental impact, it is not the only factor mentioned by Cohen.
B. Eliminating social barriers to innovation: Though social barriers to innovation can play a role in population growth, it is not specified by Cohen as a determining factor for Earth's carrying capacity.
C. Individual choices concerning consumption patterns: This is indeed one of the factors mentioned by Cohen. He argues that individual consumption patterns and choices can have an impact on Earth's carrying capacity for human populations. Therefore, option C is correct.
D. Freshwater supplies: Although freshwater supplies are important for sustaining human populations, it is not specifically mentioned by Cohen as a sole determining factor for carrying capacity.
Regarding the second question about the deadliest infectious disease, let's review the options:
Influenza: While influenza can cause severe illness and even death, it is not considered the world's most deadly infectious disease.
Hepatitis: Hepatitis, although serious, is not considered the most deadly infectious disease either.
AIDS: Yes, AIDS is considered to be one of the world's most deadly infectious diseases, so option C is correct.
Cancer: Cancer is not an infectious disease, as it does not spread from person to person. Therefore, it is not the correct answer in this context.
So, the correct answers are C (individual choices concerning consumption patterns) for the first question and C (AIDS) for the second question.
