How the comparison occurs between the current atmospheric CO 2 concentration and the concentrations over the past 420,000years. Concept introduction: The amount of CO 2 concentration in the atmosphere is quite less compared to other gases. CO 2 is the essential raw element for photosynthesis of plants, on which the life mostly depends. Usually scientists are measuring the CO 2 concentration to know the amount of increasing CO 2 concentration in the atmosphere.

Summary Introduction

To explain: How the comparison occurs between the current atmospheric CO₂ concentration and the concentrations over the past 420,000years.

Concept introduction: The amount of CO₂ concentration in the atmosphere is quite less compared to other gases. CO₂ is the essential raw element for photosynthesis of plants, on which the life mostly depends. Usually scientists are measuring the CO₂ concentration to know the amount of increasing CO₂ concentration in the atmosphere.

Summary Introduction

To explain: How the scientists know about the Earth’s CO₂ concentrations that were hundreds of thousands years ago.

Concept introduction: Global warming, climate change, and global change refer to the climatic change over the globe. Global warming is a significant increase in the average surface temperature of the Earth over various decades. Climate change refers to the alternation in climate change of the Earth for long-term.

There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?
