Describe how random mutation in an individual can result in a new adaptation in a population.
pls help
Answer:
Errors in the human genetic code, which are called mutations, sometimes lead to the production of abnormal proteins that may cause disease, including autoimmune disease and malignancy.A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
Why do individuals with low
levels of fitness die?
How do adaptations help an organism as they struggle for existence?
Answer: Not getting enough physical activity can lead to heart disease—even for people who have no other risk factors. It can also increase the likelihood of developing other heart disease risk factors, including obesity, high blood pressure, high blood cholesterol, and type 2 diabetes.
Darwin suggests that an organism's struggle for existence is part of what determines why some species' characteristics survive and others become extinct. These adaptations illustrate how unique characteristics of particular organisms have developed, allowing them to thrive in their specific environments.
What are 3 activities that release carbon dioxide into the atmosphere?
Answer:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
What are the top 3 human activities that produce CO2?
Eighty-five percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil, including gasoline. The remainder results from the clearing of forests and other land use, as well as some industrial processes such as cement manufacturing.
What causes carbon dioxide to increase in the atmosphere?
Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

What is the basic of a fatty acid
A basic fatty acid has a long chain of carbon atoms (generally even in number) along with a carboxyl group at one terminal. The fatty acid may be saturated or unsaturated depending upon the presence of double bonds.
Fatty acids are the carboxylic acids due to the presence of the carboxyl group. In an organism's body, fatty acids are the source of energy. Besides they are also involved in the formation of phospholipids which are an essential component of cell membrane.
Unsaturated fatty acids are those that contain one or more double bonds. This gives a little kink to their structure which is very essential for the fluidity of cell membranes. They are less stable than the saturated fatty acids and are also more prone to rancidity.

would you consider the relationships between changes in CO2 and Global Temperatures to be causal or correlational? EXPLAIN your answer in complete sentences.
The relationship between changes in CO2 and global temperatures is a complex and multi-faceted one, and scientists generally consider it to be both causal and correlational. On the one hand, there is strong evidence that increasing levels of CO2 in the atmosphere can cause a warming of the planet through the greenhouse effect, which is a well-established scientific principle. This is a causal relationship, as the increase in CO2 is causing a change in global temperatures.
On the other hand, there is also evidence to suggest that changes in global temperatures can impact the levels of CO2 in the atmosphere. For example, when the Earth warms, it can cause the release of CO2 from the ocean, which can then contribute to further warming. This is a correlational relationship, as changes in global temperatures are associated with changes in CO2, but one does not necessarily cause the other.
In conclusion, the relationship between changes in CO2 and global temperatures is both causal and correlational, with both factors having the potential to impact the other. It is important to understand this complex relationship in order to develop effective strategies for mitigating the effects of climate change.

Cyclic AMP phosphodiesterase is an enzyme that catalyzes the conversion of cyclic AMP to a different molecule. Which of the following best predicts the effect of inhibiting cyclic AMP phosphodiesterase in a muscle cell stimulated by epinephrine?
The concentration of cyclic AMP will decrease because adenylyl cyclase will no longer be activated.
The G protein will diffuse out of the cell because it will no longer bind to the plasma membrane.
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Glycolysis will stop because epinephrine signaling will no longer stimulate glycogen breakdown.
Answer:
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Explanation:
Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger. Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.
