D?
Thanks

34. D is the best answer.
33 c
32 b
26. complex, but years ago, it was considered inverse, and I have serious reservations about your book. Flip a coin.
Thanks so much!!

26. The relationship between population growth and resources can be described as:
c. complex; there are many contributing factors
To understand this relationship, it is necessary to consider various factors. While an increase in population can lead to an increased demand for resources, the availability of resources is influenced by various other factors such as technology, societal systems, environmental conditions, and resource management. It is not as simple as a direct inverse or parallel relationship. Therefore, the answer is c - complex; there are many contributing factors.
32. Viruses aren’t considered living organisms because they:
b. reproduce only in living cells
Viruses are not considered living organisms because they require a host cell to reproduce. They lack the ability to carry out essential life functions independently and can only replicate by infecting a living cell and taking over its cellular machinery. This makes option b - reproduce only in living cells the correct answer.
33. Biologists now know that viruses:
c. contain RNA or DNA in a protein coat
Biologists now know that viruses consist of genetic material (RNA or DNA) enclosed in a protein coat. They do not possess the characteristics of a typical living organism, such as being able to independently carry out metabolic processes or reproduce without a host cell. Therefore, option c - contain RNA or DNA in a protein coat is the correct answer.
34. Which of the following is a characteristic of protists?
d. all of the above
Protists exhibit a range of characteristics, including asexual or sexual reproduction, unicellular or multicellular cell types, and the ability to live in diverse habitats, including water. Therefore, option d - all of the above is the correct answer. Protists encompass a wide variety of eukaryotic microorganisms that do not fit into the other plant, animal, or fungal kingdoms.
