(I'm pretty sure this is biology)
Answers
Answer:
B
Explanation:
Global warming is the rise in the temperature due to greenhouse gases. It affects the ocean and increases the strength of hurricanes. Thus, option B is correct.
What is global warming?Global warming is the increased temperature due to a rise in greenhouse gases that affects the ozone layer present in the atmosphere. It also increases the temperature of the oceans.
The oceans absorb the maximum heat from the atmosphere resulting in the melting of ice caps and glaciers. This causes a change in the climate and can lead to natural disasters like flooding, hurricane, etc.
The oceanic temperature does not affect the dust formation or the evaporation of the water from the soil. Similarly, it does not possesses a health threat to the population.
Therefore, the increased global warming increases the strength of hurricanes due to the rise in oceanic temperature.

T/F mtdna, is used to trace ancestry through the female line
Answers
The statement mtDNA is used to trace ancestry through the female line is true because mitochondrial DNA (mtDNA) is passed down exclusively from mother to offspring.
Mitochondrial DNA is located in the mitochondria, which are the energy-producing organelles within cells. Unlike nuclear DNA, which is inherited from both parents, mtDNA is solely inherited from the mother.
During reproduction, the mitochondria from the sperm are typically excluded from the fertilized egg, leaving only the maternal mitochondria to be passed on to subsequent generations. This means that mtDNA carries a direct maternal lineage.
Because of this uniparental inheritance, mtDNA can be used to trace ancestry along the female line. By analyzing the sequence variations in mtDNA, scientists can establish maternal lineages and trace genetic connections through generations.

How does niche partitioning facilitate the coexistence of 20 terrestrial bird species investigated in Mohd-Azlan et al. (2014)? (200 word answer
Answers
Niche partitioning facilitate the coexistence of 20 terrestrial bird species investigated in Mohd-Azlan et al dividing resources.
Niche partitioning is a process where species divide resources in order to coexist in a particular habitat. In Mohd-Azlan et al. (2014), niche partitioning facilitated the coexistence of 20 terrestrial bird species by dividing resources. In other words, the birds have found ways to share limited resources such as food and habitat. For example, one bird species may feed on insects while another bird species feed on fruits and seeds.This allows each bird species to access its unique set of resources without direct competition with others.
Another way niche partitioning facilitated coexistence is by using different habitats. For example, some bird species may prefer to inhabit the canopy while others may prefer the understory or ground level. This helps to reduce competition for resources such as nesting sites and food. In conclusion, niche partitioning plays an essential role in facilitating the coexistence of bird species, this is achieved by allowing each species to access resources in a unique way, reducing competition and increasing the likelihood of survival.

2. Present a brief explanation of how electrical activity in the
human body interacts with electromagnetic waves outside the human
body to either your eyesight or your sense of touch.
Answers
Electrical activity in the human body interacts with electromagnetic waves outside the body to contribute to both eyesight and the sense of touch.
For eyesight, electromagnetic waves in the form of visible light enter the eye and interact with the specialized cells called photoreceptors located in the retina. When light waves reach the retina, they stimulate the photoreceptors, specifically the cones and rods. These photoreceptor cells convert the light energy into electrical signals through a process called phototransduction. The electrical signals are then transmitted through the optic nerve to the visual processing centers in the brain, where they are interpreted, resulting in the perception of vision.
Regarding the sense of touch, electromagnetic waves do not directly interact with the skin but rather with objects in the external environment. When you touch an object, pressure receptors in the skin called mechanoreceptors are stimulated. These mechanoreceptors convert the physical pressure applied to the skin into electrical signals, also known as action potentials. These electrical signals travel through sensory neurons to the somatosensory cortex in the brain, which processes and interprets the signals, allowing you to perceive the sense of touch.
In summary, electromagnetic waves in the form of visible light interact with photoreceptors in the eye, converting light energy into electrical signals for vision. For touch, electromagnetic waves indirectly interact by stimulating mechanoreceptors in the skin, which then generate electrical signals that are transmitted to the brain for the perception of touch.

explain how studying these processes can provide insights into evolutionary relationships
Answers
Studying processes such as DNA sequencing, comparative anatomy, and embryonic development can provide insights into evolutionary relationships by identifying similarities and differences between species. These similarities and differences can be used to construct phylogenetic trees, which show the evolutionary relationships between different groups of organisms.
Comparative anatomy can also provide insights into evolutionary relationships. By comparing the physical structures of different organisms, scientists can identify similarities and differences that suggest a common ancestor. For example, the presence of similar bone structures in the limbs of different mammals suggests that they share a common ancestor.Embryonic development can also reveal evolutionary relationships. By studying the development of embryos from different species, scientists can identify similarities and differences that suggest a common ancestor. For example, the early development of the vertebrate embryo is similar in all vertebrates, suggesting that they share a common ancestor.Overall, studying these processes can provide a wealth of information about the evolutionary relationships between different species, helping us to better understand the history of life on Earth.

Answers
You are studying a population of Dlugosch’s Small Octopus that has been suffering from a skin disease. In your work, you find that some individuals have more resistance (immunity) to the disease than others. You remember learning about life history trade-offs in your Ecology class, and you hypothesize that immunity trades off with investments in other major life history traits in the octopuses. You decide to design a study to test whether higher immunity leads to a lower number of eggs produced by females.
9. State a prediction for what the results of your study would look like if they support the hypothesis given in the Mission.
Make a figure of results that would be consistent with that prediction:
Label y axis with the variable that should be on the
Label x axis with the variable that should be on the
Draw results bars or lines consistent with your prediction
If the infection reduces the population size of the octopus, would you predict an r or a K strategy would be more likely to evolve (based on what we discussed in class)? Explain why that life history strategy would be favored in a small population, and give at least two traits associated with the strategy that you predict.
Answers
If higher immunity leads to a lower number of eggs produced by females in Dlugosch's Small Octopus, then there will be a negative correlation between immunity level and egg production.
A K approach would be more likely to develop if the illness causes the octopus population to decline. Resources are few in a tiny community, therefore long-term stability and survival are prioritized over rapid population expansion. The K approach emphasizes having fewer kids while allocating more resources to ensuring their survival and welfare. In a small population, the following two characteristics connected to a K strategy might be more prevalent:
Increased parental care: Parents invest more time and resources in raising a smaller number of offspring to increase their chances of survival and reproductive success.
Delayed maturation: Individuals take longer to reach reproductive maturity, allowing them to invest more time in growth, development, and building up resources before reproduction.
These traits help ensure the survival and success of the limited number of offspring in a small population, aligning with the K-selected life history strategy.
In this figure, the y-axis represents the number of eggs produced by females, and the x-axis represents the immunity level of the octopuses. The bars or lines would show a decreasing trend as the immunity level increases, indicating a negative relationship between immunity and egg production.

which protein, acting as a hormone, regulates blood glucose? a. insulin b. thyroxine c. antidiuretic d. oxytocin e. prolactin
Answers
The protein acting as a hormone that regulates blood glucose is a) insulin.
Insulin is a hormone produced by the beta cells of the pancreas and plays a crucial role in regulating blood glucose levels. When blood glucose levels rise, such as after a meal, insulin is released into the bloodstream. Insulin acts on various tissues, particularly the liver, muscle, and adipose (fat) cells, promoting the uptake and storage of glucose. It helps lower blood glucose levels by facilitating the movement of glucose from the bloodstream into these cells, where it is either used for energy or stored as glycogen.
Insulin also suppresses the production of glucose by the liver. In individuals with diabetes, either insufficient insulin is produced (type 1 diabetes) or the body's cells become resistant to the effects of insulin (type 2 diabetes), leading to elevated blood glucose levels. Insulin therapy or other treatments are used to manage and control blood glucose in individuals with diabetes.
