Question

According to Hamilton’s rule, natural selection is more likely to favor altruistic behavior that benefits an offspring than altruistic behavior that benefits a sibling.

True False

The non-venomous king snake has a red-black-yellow color pattern similar to that of the highly venomous coral snake, making this pair an example of Müllerian mimicry.

True False

Nitrous oxide, methane, and black carbon are greenhouse gases that trap heat in the Earth’s atmosphere.

True False

Climate scientists and meteorologists both use measurements of air pressure, wind, temperature, humidity, and precipitation to make predictions about future events.

True False

Mycorrhizal fungi have a parasitic relationship with plant roots.

True False

Warmer water temperatures and increased flooding may accelerate the spread of waterborne diseases such as Dengue fever.

True False

The massive extinctions of marine life that occurred during the Paleocene-Eocene Thermal Maximum were caused by a rapid increase in CO2 emissions over 4000 years.

True False

Photosynthesis and cellular respiration are two of the primary processes involved in the global carbon cycle.

True False

Answer 1

1. According to Hamilton’s rule, natural selection is more likely to favor altruistic behavior that benefits offspring than altruistic behavior that benefits a sibling

Ans. TRUE

2.The non-venomous king snake has a red-black-yellow color pattern similar to that of the highly venomous coral snake, making this pair an example of Müllerian mimicry.

Ans. FALSE

Explanation: The above given statement is an example of batesian mimicry and not Mullerian mimicry. Mullerian mimicry is a form of mimicry where two harmful species share similiarites with each other and batesian mimicry is a form of mimicry where one harmless species shares similarity with harmful species. Since the above given example states the similarity between a venomous and non venomous snake it is called batesian mimicry.

3. Nitrous oxide, methane, and black carbon are greenhouse gases that trap heat in the Earth’s   atmosphere.

Ans. FALSE

Explanation: The three main green houses gases are Ntrous oxide, methane and CO2. The above given statement mentions about black carbon which is not a gas. Black carbon is formed due to incomplete combustion of fossil fuels , wood and other fuels. Black carbon also contributes to global warming but it is not a gas, it is an aerosol.

4. Climate scientists and meteorologists both use measurements of air pressure, wind, temperature, humidity, and precipitation to make predictions about future events.
Ans. TRUE

5. Mycorrhizal fungi have a parasitic relationship with plant

Ans. False

Explanation: Mycorrhizal fungi and plants share a mutulastic relationship and not parasitic realtionship. A parasitic relationship one organism lives on another causing harm to it. But in case of mycorrhizal fungi and plants both share benefits with each other. The coloniozation of fungi in the root system results in increased absorption of water and nutrients which are utilised by the plants and the in return plants provide fungi with carbohydrates released through photosynthesis.

6. Warmer water temperatures and increased flooding may accelerate the spread of waterborne Andiseases such as Dengue fever.

Ans. FALSE

Explantion: Dengue fever is not a waterborne diease, it is a vector borne disease.

7. The massive extinctions of marine life that occurred during the Paleocene-Eocene Thermal Maximum were caused by a rapid increase in CO2 emissions over 4000 years.

Ans. False

Explanation: Paleocene-Eocene thermal maximum was associtaed with the massive extinction of marine life which resluted in rearkable diversification of marine as well as terrestrial life. It resulted because of massive volcaic eruptions that occured due sudden release of methane hydrates from the ocean sediments, This explantaion was called methane burp hypothesis

8.Photosynthesis and cellular respiration are two of the primary processes involved in the global carbon cycle.

Ans. TRUE

Explanation: Carbon cycle is a bigeochemical pathway in which carbon gas is recycled in the biosphere. Cellular respiration and photosynthesis are two main important components of carbon cycle. Carbon dioxide is relesed in the atmosphere through cellular respiration and is taken up from atmpsphere through photosyntheis
