Answer:
Lisa and Monica
Explanation:
<em>The correct answer would be Lisa and Monica.</em>
<u>For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.</u>
In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.
Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).
The correct answer to your question is C) Glucose. Hope this helps you out please let me know.
This question is rather subjective: the answer depends on how the question is interpreted. Many people would say climate change is the greatest risk to water supply, but the question mentions 'Earth's water supply'. It is a fact that the amount of water on Earth has not changed. Climate change is shifting climatic patterns, so some areas experience more droughts, whereas others experience more floods, but the amount of water on Earth still stays the same. My answer is therefore that pollution poses the greatest risk to Earth's water supply. Pollution decreases the amount of water we can safely use without expensive treatment. Some water pollution, such as certain toxic metals, pesticides or endocrine disruptors, simply can't be detected or treated using conventional water testing and treatment. Modern civilisation is resulting in unsustainable amounts of pollution being released into our rivers and lakes, and sooner or later, a threshold of no return will be reached, where ecological collapse will mean we won't be able to rely on these water resources for fresh water anymore.
