proximate causation is explain immediate cause of behavior in terms of stimuli, produces behaviors evolved through Darwinian fitnesstrue or false

Answers

Answer 1

True. Proximate causation refers to the immediate cause of behavior in terms of stimuli, such as sensory inputs, hormonal changes, and neural activity. This type of causation is focused on the mechanisms that produce behavior in the here and now, rather than on the evolutionary history of the behavior.

On the other hand, ultimate causation refers to the evolutionary history of behavior and how it has evolved through Darwinian fitness.

This type of causation is focused on the adaptive value of behavior in the context of the environment in which it evolved. While proximate causation and ultimate causation are often studied separately, they are both important in understanding the full picture of why organisms behave the way they do.

Overall, proximate causation is necessary for understanding the immediate factors that produce behavior, while ultimate causation is necessary for understanding how that behavior has evolved over time.

Answer 2

The statement is true. Proximate causation explains the immediate cause of behavior in terms of stimuli and responses, while behaviors have evolved through the process of natural selection, leading to increased Darwinian fitness in organisms.

True. Proximate causation refers to the immediate cause of a behavior, which can be explained in terms of stimuli such as hormones, environmental factors, or neural pathways. However, this type of causation does not necessarily explain why a behavior has evolved over time. To understand the evolutionary basis of a behavior, one would need to consider ultimate causation, which involves exploring how the behavior contributes to an organism's fitness and survival. Ultimately, behaviors that enhance an organism's Darwinian fitness are more likely to be passed down through generations.

Within a few weeks of treatment with the drug 3TC, a patient's HIV population consists entirely of 3TC-resistant viruses. How can this result best be explained.
A. Each HIV particle can change its surface to evade vaccines.
B. HIV particles began making drug resistant versions of themselves in response to the drug.
C. A few drug-resistant viral particles were present at the start of treatment, and natural selection increased their frequency.
D. The drug caused the HIV RNA to mutate in a favorable manner.

Answers

The best explanation for a patient's HIV population is C: A few drug-resistant viral particles were present at the start of treatment, and natural selection increased their frequency.

The drug 3TC is a nucleoside reverse transcriptase inhibitor (NRTI) that works by blocking the reverse transcriptase enzyme that the HIV virus uses to replicate its genetic material. However, some HIV viruses may have mutations that allow them to resist the effects of the drug. If these drug-resistant viruses are present in a patient's HIV population before treatment, they may become more prevalent over time as natural selection favors their survival and reproduction in the presence of the drug.

In other words, the drug may kill off the non-resistant viruses, allowing the drug-resistant viruses to become the dominant population. This phenomenon is a common problem in the treatment of viral infections, where the use of drugs can lead to the development of drug-resistant strains over time. It underscores the importance of using drugs in combination to minimize the risk of drug resistance and to continue to develop new drugs to combat evolving viral strains.

These genes are responsible for the transmission of traits from one generation to another, which is the basis of heredity.

Variation in genetics refers to the differences in traits that exist among individuals within a population. This variation can be attributed to differences in the structure, number, and arrangement of genes on chromosomes. Cytogenetics plays a crucial role in understanding how these variations occur and how they influence the inheritance of traits. By studying the structure and behavior of chromosomes, cytogeneticists can identify abnormalities or mutations that may lead to genetic disorders or contribute to the diversity of traits within a population.

In summary, cytogenetics is the branch of genetics that focuses on the relationship between chromosomes, heredity, and variation.

Net primary productivity increases over successional time as plants compete more directly with each other

Answers

Net primary productivity (NPP) is the amount of organic matter produced by photosynthesis in plants minus the amount of energy they use in respiration. NPP is an important measure of the amount of energy available to support ecosystems.

As ecosystems mature and undergo successional changes, the competition for resources among plants becomes more intense. This competition can lead to an increase in NPP.

During early successional stages, plants are typically spaced further apart and have more access to resources such as sunlight and nutrients. As these resources become depleted, the plants compete more directly with each other for them. This competition leads to an increase in the efficiency of photosynthesis and a higher NPP. This is because plants are more efficient at converting sunlight into energy and are able to capture more nutrients.

Overall, the increase in NPP over succession time reflects the ability of ecosystems to adapt and change in response to environmental conditions. It is an important indicator of the health and productivity of ecosystems and can help us understand how ecosystems will respond to future changes in the environment.
