3) Illustrate the observed pattern of relatedness of organisms versus adaptations to specific conditions. This means the biogeographic pattern of closely related groups of organisms showing adaptations to very different conditions and distantly related organisms looking superficially similar to each other by way of adaptations to a similar environment.
two types of patterns are observed organisms in relation to adaptation
convergent evolution
divergent evolution
biogeographical patterns tell us how species are related to each other.
convergent evolution: when distantly related organisms looking superficially similar to each other by way of adaptations to a similar environment. Convergent evolution can be technically defined as the development of similar features as a result of independent evolution from different ancestral traits. i.e. 2 very unrelated organism will show similarity in many features due to environmental conditions.these are the adaptations in response to the same selective pressures. For example, a totally unrelated organism of the same geographic conditions acquire similar traits through independent evolution .this happens because of their similar life pattern or the same environmental conditions. Without having the same ancestral lineage these organisms will show similar traits.
divergent traits: when closely related groups of organisms showing adaptations to very different conditions. Divergent evolution is the accumulation of certain differences between very closely related species which eventually; lead to speciation. Due to some environmental conditions, two organism of closely related species develop some features different from the other, these are the adaptations to different factors which ultimately become inherent and passed onto progeny leading to speciation. This occurs when the organism of same species live in two different environmental conditions.

3. This is a schematic of a very simple pattern of gene expression. Yes means the protein is present and can bind the promoter. No means the protein is absent. Transcription factors are proteins that help regulate transcription by binding DNA Activators are transcription factors that help transcription. For example, they bend the promoter and make it accessible to RNA polymerase. Repressors are transcription factors that inhibit transcription. For example, they might bind the promoter and stop the RNA polymerase...

CHAPTER 12: SEXUALLY TRANSMITTED INFECTIONS:
HIV/AIDS AND OTHER COMMUNICABLE CONDITIONS
Critical Thinking Exercise: Causes of Death Around the World
The Institute for Health Metrics and Evaluation reported that
the topography of disease-related deaths has changed over many
generations, and that different diseases, both communicable and
noncommunicable, are starting to affect communities differently.
Specifically, the researchers identify that the typical life
expectancy has increased on a global scale, which means there are
now different, previously unknown risks and causes of illness...
Coding for Python - The pattern

'print' or 'input' statements.
Context of the assignment is:
In this assignment, your goal is to write a Python program to
determine whether a given pattern appears in a data series, and if
so, where it is located in the data series. Please see attachments

Could someone please check my answers? 1. A researcher uncovers a fossil in South America that looks quite similar to a species that currently lives in Africa but does not resemble other South American species. The climate and vegetation in the two locations are very different. What is the MOST likely explanation? A. The fossil must have been transported across the ocean during storms. B. The species are probably not closely related due to convergent evolution. C. There was probably...

Which two groups are more closely related to each other and to land plants? green algae and brown algae green algae and red algae red algae and brown algae 2.The simplest and most evolutionarily ancient primary producers are: diatoms cyanobacteria (AKA bluegreen algae) unicellular algae plants dinoflagellates Ocean water is salty because there are ions (salts) dissolved in the water.

Elspeth, associate research specialist for a marketing research firm in a large Midwestern city, had just moderated a very successful focus group for a regional personal injury law firm. The focus group represented two firsts: it was the first time Elspeth had moderated a focus group, and it was the first time the law firm had used any type of marking research. The purpose of the study was to aid the law firm’s partner in charge of marketing in developing...
