The images show a pictorial description of parts of the carbon cycle.
Carbon cycleThe carbon cycle shows the flux of carbon between the living and non-living components of the ecosystem.
In the first and second images, carbon is released into the atmosphere as carbon dioxide from the respiratory activities of living organisms - Albert Estein and T-Rex.
This carbon in the atmosphere is made use of by plants in a process known as photosynthesis. Plants are able to fix carbon into carbohydrates using this process.
Humans are able to get carbon directly from plants by consuming plant produce or indirectly by consuming the meat of organisms that feed primarily on plants themselves.
Thus, the above explains the illustrations in the image.

Answers
Convergent evolution, because these organisms do not share a recent common ancestor.
What is convergent evolution?Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.
Moreover, convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures. Traits that arise through convergent evolution are referred to as 'analogous structures'. They are contrasted with 'homologous structures', which have a common origin.
Therefore, convergent evolution—in which distinct lineages independently evolve similar traits—has fascinated evolutionary biologists for centuries, in large part because convergent evolution is often thought to represent a visible manifestation of the power of natural selection.

describe how genetic information is coded in dna, listing the characteristics of the code and explaining its degeneracy.
Answers
The genetic information is coded in DNA because this molecule contains all the info to synthesize proteins, the genetic code is degenerated because different codons can be used to synthesize the same amino acid during the translation.
Why the genetic code is degenerated?The genetic code is degenerated because different triplets of nucleotides in the DNA sequence can be used to synthesize the same amino acid, which are called synonym codons.
The DNA molecule contains fragments called genes that generate proteins by the successive processes of transcription and translation, as well as regulatory non coding sequences that control the process of transcription
Therefore, with this data, we can see that the genetic code is degenerated because there are different codons are also able to generate the same amino acid during the process of protein synthesis, i.e., during the translation.

What is a Punnett square?The Punnett square is a square diagram often used predict genetic traits of a specific cross or breeding experiment.
It is named after Reginald C. Punnett, who invented it in 1905. Biologists use the diagram to calculate the likelihood of an offspring having a specific genotype.
The Punnett square is a chart that enumerates all of the potential scenarios of a genetic cross between two people with known genotypes.
The Punnett square, in its most basic form, is a square divided into four quadrants.
A Punnett Square is a useful tool for predicting the variations and probabilities that can result from cross breeding. This includes predicting the intercrossing of plants, animals, and even humans.
For the given scenario, the genotype of the offspring will be BB and Bb as per the attached Punnett Square.

Which of the following statements is true regarding the absorptive and postabsorptive states? Check all that apply The absorptive state only lasts for approximately 30 minutes after a meal. During the absorptive state nutrients may be used immediately to meet energy demands. Glycogenolysis is most likely utilized to meet energy demands during the postabsorptive state, Blood glucose drops dramatically during the absorptive state. Gluconeogenesis most likely occurs at least 4 hours after the last meal.
Answers
The statements that are true regarding absorptive and post-absorptive are -
option (2): During the absorptive state nutrients may be used immediately to meet energy demands
option (3): Glycogenolysis is most likely utilized to meet energy demands during the post-absorptive state
option (5): Gluconeogenesis most likely occurs at least 4 hours after the last meal.
What is absorptive and post-absorptive state?Absorptive stage = fed state and post absorptive stage = fasting state.
The absorptive state is the time when ingested nutrients enter the circulation and part of these nutrients meet the body's energy needs while the rest is stored. The post-absorptive stage is the time when the GI system is depleted of nutrients and the body must rely on stored energy.
Option 2: Nutrients can be utilized directly to fulfill energy demands during the absorptive period.
Explanation: Taking a glucose solution while exercising provides athletes with instant energy. As glucose begins to be absorbed from the mouth.
Option 3: Glycogenolysis is most likely used to supply energy requirements during the post-absorption period.
Explanation: During the post-absorptive phase, the liver glycogen begins to break down and create glucose for the body's energy source.
Option 5: Gluconeogenesis happens at least four hours after the last meal.
Explanation: Our bodies require extra energy after around four hours of absorption. The gluconeogenesis process then begins.

Option 1: The absorptive condition lasts 4 hours, not 30 minutes.

Drag the labels onto the flow chart to trace the movement of proteins through the endomembrane system and out of the cell
Answers
This is the sequence of protein synthesis and transport of secreted proteins: the first step is rough ER, the vesicle from ER, golgi appartus, the vesicle from golgi, and then finally it goes out of the plasma membrane.
How do the proteins go out of the cell?
The protein is synthesized on the rough ER surface and then enters the ER lumen. The vesicle exits the ER and travels to the golgi apparatus, which contains the protein, where it undergoes further modification. From the golgi, the modified protein goes out of the cell through the vesicle.
Hence, the sequence is rough ER-vesicles from ER- Golgi apparatus, vesicles from Golgi apparatus- and plasma membrane.

One theory is that evolution takes place. In other words, organisms undergo gradual change. As offspring from ancient common ancestors diverged, life on Earth has transformed.
What is Voyage in Darwin?The second hypothesis proposes that natural selection drives evolution. Natural selection is the process through which living creatures that possess advantageous qualities have more offspring than those that do not. As a result, over time, the characteristics of living things change.
Most people in Darwin's day thought that all species were formed simultaneously and then stayed unchanging. Additionally, they thought Earth was only 6,000 years old. Darwin's theories so transformed biology.
Darwin embarked on a scientific journey in 1831 when he was only 22 years old on board the HMS Beagle. He served as the expedition's naturalist. Wherever the expedition went ashore, it was his duty as a naturalist to examine and gather samples of plants, animals, rocks, and fossils.
