Answer:
Vertical distance between contours is called contour interval
Explanation:
Contour lines are lines that connects point of equal height. The vertical distance or the difference in elevation between two contour lines is known as contour interval. For example a set of 100 contours is used to represent a hill of height 500 ft. So, the vertical distance between each contour will [tex]\frac{500}{100} \\[/tex]feet

Cytochrome c can be reduced directly by small molecules such as ascorbate (vitamin c). if ascorbate is added to an oxygenated solution containing purified cytochrome c and cytochrome oxidase, what would you predict would occur?
a.atp synthesis would occur.
Ascorbate would reduce cytochrome c by donating electrons, which could then be passed to cytochrome oxidase and then to oxygen. However, this process does not directly cause ATP synthesis.
Explanation:If ascorbate, or vitamin C, is added to an oxygenated solution containing purified cytochrome c and cytochrome oxidase, it would donate electrons to the cytochrome c. This would reduce the cytochrome c. The reduced cytochrome c can then pass the electrons to the cytochrome oxidase, which then transfers the electrons to oxygen. This is a crucial part of the electron transport chain, which is involved in cellular respiration. However, the donation of electrons by ascorbate and its transfer through cytochrome c and cytochrome oxidase would not directly result in ATP synthesis. ATP synthesis occurs in another part of cellular respiration called oxidative phosphorylation, which requires a proton gradient established by the electron transport chain, but not ascorbate.

The bullock's oriole and baltimore oriole are closely related, but are they of the same species? to find out, you could see whether they ___.
To figure out if the Bullock's oriole and the Baltimore oriole are the same species, check if they can produce viable, fertile offspring. Even with different feeding habits in the same habitat, they might still be the same species if they can interbreed. But similarities like wings in birds and butterflies don't guarantee them as the same species as they could be results of convergent evolution.
Explanation:To determine if the Bullock's oriole and the Baltimore oriole are of the same species, one could see whether they can successfully produce viable, fertile offspring. This is because according to the Biological Species Concept, two organisms are considered to be of the same species if they can interbreed and produce viable, fertile offspring. Both the Bullock's oriole and the Baltimore oriole are closely related and live in the same habitat, but have different feeding habits. However, they might still be of the same species.
For example, consider two species of birds that diverged while separated geographically but resumed their contact before reproductive isolation was complete. If these two bird species were able to interbreed, they would be considered the same species according to the Biological Species Concept.
On the other hand, birds and butterflies both have wings with similar characteristics for flight, but this does not necessarily indicate that they are the same species. Such similarities could be due to convergent evolution, where unrelated organisms independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

Weather anomalies can be used as evidence for and against climate change.C. In the last 10 years, Earth has been cooling off.D. In the last 10 years, sea level has risen twice as fast as in previous centuries.
The claim that sea level has risen twice as fast in the last 10 years as in previous centuries is supported by significant scientific research. Option D is correct.
The Intergovernmental Panel on Climate Change (IPCC), the leading international body for the assessment of climate change, has concluded that it is extremely likely that human activities caused more than half of the observed increase in global mean surface temperature from 1951 to 2010. The IPCC has also concluded that the rate of sea level rise has accelerated in recent decades, and that this is largely due to human-caused climate change.
The other claims are not supported by significant scientific research. Claim A is contradicted by the overwhelming scientific consensus that human activities are causing global warming. Claim B is too simplistic, as weather anomalies can be caused by a variety of factors, both natural and human-caused. Claim C is not supported by the data, as global average temperatures have continued to rise in recent years. Option D is correct.

The bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs. the bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the rbcs.
a. True
b. False
The statement is false as carbaminohemoglobin carries only about 20 percent of carbon dioxide in the blood, with the majority being transported as bicarbonate ions created by the action of carbonic anhydrase.
Explanation:The statement that the bulk of carbon dioxide is carried chemically combined with the amino acids of hemoglobin as carbaminohemoglobin in the red blood cells (RBCs) is false. While some carbon dioxide is carried in this form, carbaminohemoglobin accounts for about 20 percent of carbon dioxide transport in the blood. The majority of carbon dioxide, approximately 85 percent, is transported as bicarbonate ions in the plasma. This process occurs when carbon dioxide diffuses into red blood cells and is converted by the enzyme carbonic anhydrase to carbonic acid, which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions are transported out of the red blood cells into the plasma in exchange for chloride ions, a mechanism known as the chloride shift.
