Cladograms are graphic representations of the relationship between different taxa according to derivated characters. Option A is correct. Group D has a segmented body and jaws, but no limbs.

A Cladogram is a graph drown as a tree, which is based on cladistic analysis. It represents the common ancestral relationships and the emergence of different characters among the involved groups.

Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

In the provided cladogram, segmentes bodies, jaws, limbs and other traits are derivated characters.

Group D has a segmented body and jaws, but does not express limbs.

This last trait emerged later in history and is expressed by groups E, F and G.

Option A is correct. Group D.

The property that describes the ability of blood to move readily through vessels because it contains a high volume of water is: low viscosity.

Blood is the fluid that facilitates the transport of various substances across the whole body. It is a red-colored fluid that receives its color due to a pigment called hemoglobin. The substances that blood can transport are: gases like oxygen and carbon dioxide, waste material, hormones, immune cells, etc.

Viscosity is the property of fluids that determines the resistive power of fluids. The more a liquid is viscous, the more it has the resistive power to move or change its shape. Water has very less viscosity and hence can easily move or change shape according to the vessel it is present in.

The given statement " Drosophila cells divide every 60 minutes during the first 13 cycles of development." is True. This is a phenomenon known as "endoreplication".

Endoreplication occurs when a cell enters a state of repeated rounds of DNA replication without the intervening cell divisions.

Endoreplication is a phenomenon where cells undergo repeated rounds of DNA replication without the concomitant cell divisions. This leads to an increase in the ploidy of the cell and can result in the formation of large polyploid cells with multiple copies of the genome.

During the first 13 cycles of Drosophila development, the cells undergo endoreplication, which is responsible for the rapid increase in cell size and number. In Drosophila, this endoreplication occurs every 60 minutes, resulting in the doubling of the genome content with each round of replication.

Endoreplication is often observed in specialized cells that require high levels of gene expression and metabolic activity, such as in the salivary glands of Drosophila. Endoreplication can also occur in cancer cells, where it contributes to the increased genetic instability and heterogeneity of the tumor.

Overall, endoreplication is an important process that allows cells to rapidly increase their genome content and achieve specialized functions, and its study in model organisms such as Drosophila can provide valuable insights into the mechanisms that regulate cell growth and differentiation.

Out of the given options, there is no factor that does NOT affect hemoglobin's affinity for oxygen. All the mentioned factors, i.e., pH of blood, partial pressure of oxygen, and the level of carbon dioxide in the blood, have an impact on the hemoglobin's ability to bind and release oxygen.

For instance, high levels of carbon dioxide in the blood lead to the formation of more acidic compounds, which can reduce the pH of blood and weaken hemoglobin's ability to bind to oxygen. Similarly, changes in partial pressure of oxygen or temperature can alter the oxygen binding and releasing capacity of hemoglobin. Therefore, all the mentioned factors have a crucial role in regulating the oxygen-carrying capacity of hemoglobin in the blood.

The factor that does NOT affect hemoglobin's affinity for oxygen among the given choices is the temperature level of carbon dioxide in blood. Hemoglobin's affinity for oxygen is mainly influenced by the pH of blood (Bohr effect), partial pressure of oxygen, and temperature. While carbon dioxide levels can indirectly affect pH, the temperature level of carbon dioxide itself does not directly impact hemoglobin's affinity for oxygen.

The problem of fat vs thin tails in establishing the price of carbon refers to the challenge of determining the appropriate price for carbon emissions. It involves considering the potential risks and uncertainties associated with climate change, particularly extreme events with low probabilities but high impacts.

Weitzman's index in the Noah's Ark framework is used to prioritize which species to save based on certain factors. However, not all species may be saved due to limitations such as practical feasibility, resource constraints, and the trade-offs involved in conservation decisions.

a. The problem of fat vs thin tails in establishing the price of carbon can be explained by considering the risks and uncertainties associated with climate change. The "fat tails" refer to the possibility of extreme and rare events occurring, such as catastrophic climate impacts. On the other hand, the "thin tails" represent more predictable and moderate outcomes. Establishing the price of carbon involves assessing the potential damages and risks associated with climate change and incorporating them into the pricing mechanism. The challenge lies in determining how to account for the fat tail events, which have low probabilities but could have severe consequences. It requires balancing the need to address the worst-case scenarios while considering the economic impacts and uncertainties involved.

b. Weitzman's index of which species to save in the Noah's Ark framework takes into account various factors when prioritizing conservation efforts. These factors may include a species' uniqueness, ecological significance, and evolutionary distinctiveness. However, not all species can be saved due to practical limitations and trade-offs. Conservation efforts often face resource constraints, making it impossible to protect all species equally. Additionally, the practical feasibility of conservation actions, such as habitat preservation or captive breeding programs, may vary among species. The decision-making process involves considering the potential benefits and costs associated with saving different species, taking into account available resources and the overall goal of preserving biodiversity. Therefore, while Weitzman's index provides a useful framework for prioritizing species conservation, it does not guarantee the preservation of all species due to practical constraints and trade-offs involved in conservation decision-making.

During the Cretaceous period, high temperatures and abundant vegetation resulted in increased \(CO_2\) levels, leading to the accumulation of organic matter and the formation of good source rocks for oil and gas.

During the Cretaceous period, spanning from approximately 145 to 66 million years ago, the global carbon-climate cycle played a crucial role in the development of favorable conditions for the formation of good source rocks. The period was characterized by high global temperatures and abundant vegetation, resulting in increased carbon dioxide \((CO_2)\) levels in the atmosphere.

The elevated \(CO_2\) levels fueled vigorous photosynthesis, leading to the accumulation of organic matter in marine and terrestrial ecosystems. As this organic matter was buried and subjected to heat and pressure over millions of years, it transformed into oil and gas, creating potential source rocks.
