7. What is an index fossil? What do index fossils reveal about other material found with
them?
Answer:
Index fossils are fossils that are widespread but only existed for a short period of time. Index fossils help scientists to find the relative age of a rock layer and match it up with other rock layers. Living fossils are organisms that haven't changed much in millions of years and are still alive today.
By Pleistocene hangovers, Buchanan means: Biological traits that we have today that are the result of selective pressures that existed thousands of years ago but no longer today. Biological traits that we have today but would not have had in the environment that existed thousands of years ago. Biological traits that are better in terms of quality of life to have today, even though the selective pressures that allowed for those traits do not exist today. Selective pressures toward perfection that feel like a hangover because perfection is impossible. Selective pressures that exist today that tend to push human beings away from the pursuit of perfection.

What do you call the portion of DNA strand that is transcribed?
Answer: DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand. The nontemplate strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.

Transportation infrastructure has a negative impact on the ecosystem in a variety of ways. One of the impacts of
transportation infrastructure on ecosystems is habitat fragmentation. Fragmented habitats may then be subject to the edge
effect. The edges of habitats so unique that they have their own sets of physical conditions and communities of organisms.
When habitats become fragmented their edges often become more abrupt and transition is less gradual than it would
naturally. In a naturally occurring edge we would expect plants that tend to be shade-intolerant and tolerant of cry
conditions. Animals that colonize edges tend to be those that require two or more habitats, such as white-tailed and mule
deer, elk, cottontail rabbits, blue jays, and robins.
Consider the image above. The paving of the road on the left could result in all BUT ONE of the negative situations described
A)
Successful invasion of non-native species.
B)
Changes in species abundance and distribution
Chance of increased erosion and further degradation of the area.
D)
Provide habitats for species that thrive where there is more light.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

A gene that has many possible genotypes such as brown, red, blonde, green, blue, or hazel is known as a
A polygenic trait
B single gene trait
C polygraphic trait
D single ladies trait by Beyonce
Answer:
I think the answer would be C.
Explanation:
D is wrong for obvious reasons, elimanate any silly or impossible answers.
Since poly means muliple, and single means, not muliple (in most cases), B is elimanated.
Since Grapihic usaully refers to things that can been seen, where genic ussaully refers to more so like personality characteristics.

Which of the following correctly describes the flow of carbon in the carbon cycle?
a. Air ---> animals ---> plants
b. Plants ---> animals ---> air
c. Air ---> fossil fuels ---> animals
d. Fossil fuels ---> plants ---> animals
Answer:
(b) Plants ---> animals ---> air.
Since the cycle begins with the process of Photosynthesis as carbon dioxide is absorbed then becoming Carbon compounds. These are taken by primary consumers passed to secondary consumers then to tertiary consumers.
Then three processes takes place (respiration, Decomposition and Combustion) finally carbon dioxide is given out again.
