Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>
2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.

If two Bb guinea pigs cross, there are four possible outcomes:
- both pass the B: the son is BB
- one of the pass the B and the other pass the b: the son is Bb
- both pass the b: the son is bb
Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.
So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.
Answer:
They allow for automatic biogeographic isolation
Repeated exposure to radiation can increase the risk of cancer.
<h3>What is cancer?</h3>
- A set of illnesses known as cancer involve abnormal cell proliferation and have the ability to invade or spread to different bodily regions.
- In contrast to this, benign tumors do not spread.
- A lump, unusual bleeding, a persistent cough, unexplained weight loss, and a change in bowel habits are all potential warning signs and symptoms.
- These signs of cancer may be present, but there may be other causes as well.
- Humans are susceptible to over 100 different malignancies.
<h3>What are the four primary cancer types?</h3>
- Carcinomas. The skin or the tissue that covers the surface of internal organs and glands is where a carcinoma first appears.
- Sarcomas. The tissues that support and bind the body give rise to sarcomas.
- A cancer of the blood is leukemia.
- Lymphomas.
