Offer a possible evolutionary explanation for how the bones of animal limbs can have a similar
structure, but very different functions.
The bones of animal limbs that are similar in structure but have different functions are called homologous structures and are explained through divergent evolution.
What are homologous structures?
Homologous is a word derived from the Greek words - 'Homo' and 'logos' meaning 'same ratio or proportion'. Homologous structures are ones that have similar structures, features, traits, and/or characteristics. In animals, this refers to mostly the body parts such as bones and limb structures.
When it comes to evolutionary biology, homologous structures help map back the ancestors and form possible connections to other animals across species.
When it comes to homologous structures it is referred to as divergent evolution. Divergent evolution involves organisms that seem to have come from the same ancestor but evolved to adapt to their surroundings changing the functions of their similar body structures.
Common examples of homologous structures are the structures of the limbs of humans and a cat.

The heart is divided into four chambers: the right atrium, the right ventricle, the left atrium, and the left ventricle. The right atrium and right ventricle make up the right side of the heart, and the left atrium and left ventricle make up the left side of the heart.
The numbers on the model represent the percentage of oxygen in the blood. The blood on the right side of the heart has a lower percentage of oxygen than the blood on the left side of the heart. This is because the blood on the right side of the heart has just returned from the tissues, where it has lost oxygen.
The blood on the right side of the heart goes to the lungs, where it picks up oxygen. The blood then goes to the left side of the heart, and from there it is pumped to the tissues. The tissues use the oxygen in the blood, and the blood then returns to the right side of the heart to start the cycle again.
The model shows that the amount of oxygen in the blood changes as it travels through the body. The blood picks up oxygen in the lungs and loses oxygen in the tissues. This is why it is important to have a healthy circulatory system. A healthy circulatory system ensures that the blood can deliver oxygen to all parts of the body.

Whoever helps me asap and gives the best answer I will mark as brainliest!Part 2: David’s Physical Condition
At his trial, David’s defence argued that his behaviour had not been under his control. Shortly before his behaviour changed, David had accidentally been exposed to a high concentration of an organophosphate pesticide called carbaryl. Carbaryl is a substance that can have an effect on the nervous system. In fact, it behaves similarly to many nerve gasses (chemical weap-ons that exert their effect by impairing the functioning of the nervous system). Carbaryl works by affecting the way that brain cells communicate with each other. This communication occurs at synapses,little gaps at the junctions of nerve cells. Neurones (nerve cells) release chemicals to send signals across the gap. These chemicals are called neurotransmitters. After it has been released, the neurotransmitter is broken down to prevent it from stimulating the post-synaptic neurone for any longer than necessary. Carbaryl prevents the breakdown of a neurotransmitter called acetylcholine (ACh). Exposure to high doses of carbaryl causes ACh to build up in the brain and other parts of the nervous system. One of the many parts of the brain that uses ACh is a structure called the hypothalamus. This structure is important in a huge range of behaviours including eating, drinking, sex, and aggression. Electrical stimulation of specific parts of the hypothalamus can cause a rat to show signs of rage and attack behavior. David’s defence argued that the carbaryl to which he had been exposed had affected the functioning of his hypothalamus. A small provocation would have started the parts of the hypothalamus associated with attack behaviours to start firing. However, because of the carbaryl, they would not have been able to stop, leading to uncontrolled rage and aggression.
Discussion Questions:
• Based on the evidence provided, do you think David is morally responsible
for his crime?
• What possible environmental influences may have incited David to act as he did?
• Why do you think the jury believed the prosecution in spite of the defence’s
argument?
• How does this case affect your views on the nature versus nurture debat
1. Determining moral responsibility in cases like these can be complex. While David's defense argued that his behavior was a result of the exposure to carbaryl, the concept of moral responsibility takes into account the ability to understand the consequences of one's actions and to make choices accordingly.
If David's exposure to carbaryl significantly impaired his ability to control his behavior and make rational decisions, it could potentially diminish his moral responsibility for the crime.
However, the assessment of moral responsibility is subjective and can depend on legal, ethical, and societal perspectives.
2. The primary environmental influence highlighted in this scenario is David's accidental exposure to the high concentration of carbaryl, an organophosphate pesticide.
Carbaryl, by affecting the communication between brain cells, particularly in the hypothalamus, may have disrupted the normal functioning of David's brain and influenced his behavior.
However, it's worth noting that other environmental factors, such as upbringing, social influences, previous experiences, and stressors, could also play a role in shaping an individual's behavior.
3. The jury might have found the prosecution's case more convincing due to factors such as:
a) Counter Arguments or lack of sufficient evidence presented by the defense.
b) Bias or preconceived notions of the jury members.
c) The prosecution's ability to present a compelling narrative and connect the evidence to David's actions.
d) The jury's limited understanding of the complexities of neurobiology and the effects of substances like carbaryl on behavior.
4. The nature versus nurture debate centers around the relative influence of genetic factors (nature) and environmental factors (nurture) in shaping an individual's traits, behaviors, and actions.
This case highlights the significant impact of an environmental factor, namely the exposure to carbaryl, on David's behavior.
It suggests that environmental influences, in this case, chemical exposure, can have profound effects on neural functioning and subsequent behavior.

Explanation:
Scientific knowledge is open to change because it is based on the systematic and ongoing process of observation, experimentation, and analysis. As new evidence becomes available, scientists reassess their theories and hypotheses to align with the most accurate and current understanding of the subject.
In the case of Giovanni Schiaparelli's observations of Mars, his initial interpretation of the lines on the planet's surface as "channels" was later translated into English as "canals." Percival Lowell further popularized this idea by drawing maps depicting a fictional Martian civilization with a network of canals.
However, as technology improved and more detailed observations of Mars were made with better telescopes, it became clear that there were no actual canals on the planet. The new evidence did not support the earlier interpretations of observations, indicating that the existence of Martian canals was a misinterpretation or a product of human imagination.
This example demonstrates how scientific knowledge can evolve and change based on new evidence that challenges or contradicts previous ideas. It highlights the importance of critical evaluation, rigorous experimentation, and openness to revising theories in the face of new information.
