Which organism will most likely become fossilized from being buried in sediment? Insect , snail, jellyfish or a worm
Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.

Explanation:
Air pollution affects everyone equally is true statement.
What is Air pollution?When pollutants are released into the atmosphere, they endanger both human health and the health of the entire planet. The World Health Organization (WHO) estimates that air pollution causes close to seven million deaths worldwide each year.
Currently, nine out of ten people breathe air that contains more contaminants than the WHO's recommended levels, with those in low- and middle-income nations suffering the most.
The 1970-established Clean Air Act gives the U.S. Environmental Protection Agency (EPA) the power to protect public health by controlling the emissions of certain dangerous air pollutants.
Therefore, Air pollution affects everyone equally is true statement.

form and function are related. describe how the form of the tracheal wall is related to its four functions
Given what we know we can confirm that the tracheal wall is related to its function in that it allows it to conduct air in a sealed manner and protect the individual.
What is the function of the trachea?The primary function of the trachea is to conduct air into the lungs. For this, the trachea is long and narrow, to allow air to flow in a directed manner towards the lungs. The trachea is also "armored" to protect this air flow and is lined with mucus to sweep away any unwanted particles from the air.
Therefore, we can confirm that the trachea is armored and lined with mucus along its long, tube-like shape, which allows this structure to conduct air in a safe, clean, and direct manner directly towards the lungs.

how does flouride cause kidney deasies
Answer:
Hepato- and nephrotoxicity of fluoride have been demonstrated in animals, but few studies have examined potential effects in humans. This population-based study examines the relationship between chronic low-level fluoride exposure and kidney and liver function among United States (U.S.) adolescents. This study aimed to evaluate whether greater fluoride exposure is associated with altered kidney and liver parameters among U.S. youth.
This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (2013–2016). We analyzed data from 1983 and 1742 adolescents who had plasma and water fluoride measures respectively and did not have kidney disease. Fluoride was measured in plasma and household tap water. Kidney parameters included estimated glomerular filtration rate (calculated by the original Schwartz formula), serum uric acid, and the urinary albumin to creatinine ratio. Liver parameters were assessed in serum and included alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, blood urea nitrogen, gamma-glutamyl transferase, and albumin. Survey-weighted linear regression examined relationships between fluoride exposure and kidney and liver parameters after covariate adjustment. A Holm-Bonferroni correction accounted for multiple comparisons.
The average age of adolescents was 15.4 years. Median water and plasma fluoride concentrations were 0.48 mg/L and 0.33 μmol/L respectively. A 1 μmol/L increase in plasma fluoride was associated with a 10.36 mL/min/1.73 m2 lower estimated glomerular filtration rate (95% CI: −17.50, −3.22; p = 0.05), a 0.29 mg/dL higher serum uric acid concentration (95% CI: 0.09, 0.50; p = 0.05), and a 1.29 mg/dL lower blood urea nitrogen concentration (95%CI: −1.87, −0.70; p < 0.001). A 1 mg/L increase in water fluoride was associated with a 0.93 mg/dL lower blood urea nitrogen concentration (95% CI: −1.44, −0.42; p = 0.007).
Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents. As the study is cross-sectional, reverse causality cannot be ruled out; therefore, altered kidney and/or liver function may impact bodily fluoride absorption and metabolic processes.

The graph shows the change in seabird mortality rates in New Zealand waters due to illegal, unreported, and unregulated fishing (IUU) and the implementation of bycatch remediation measures in 2004. What conclusion can be made about the impact of the remediation measures that were used?
Illegal and unregulated fishing practices continue to cause increases in bird bycatch numbers, in spite of the new measures.
Legal fishing practices have caused the new remediation measures to become more effective.
The measures virtually eliminated all of the bird bycatch.
The measures used showed very little impact on the overall seabirds caught in fishing lines.
According to the graph, the measurements practically eliminated all incidental captures, as shown in the third answer option.
What does the graph show?Illegal capture practices show a high performance between 1997 and 2003.Illegal capture practices show a low performance from 2004 and this performance tends to fall in the next years until it presents very low values.Legal capture practices maintain a balanced performance.The decrease in the performance of illegal practices from 2004 onwards, shows how the remediation measures were efficient in reducing the activity of these practices and providing a better environmental well-being.

Answer:
The correct option is "D", the sigmoid phenomenon because Populations that exhibit the sigmoid pattern increase rapidly while food and habitat are abundant, and then slow down as regulatory factors such as lower birth rate and reduced food availability come into play. As the rate of population growth slows down to zero, the population reaches a fairly stable level.
