compare and contrast the five types of evidence that support the theory of evolution
There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology. The basic idea of natural selection is that a population of organisms can change over the generations if individual having certain heritable traits leave more offspring than other individuals. The result of natural selection is evolutionary adaptation, a population’s increase in the frequency of traits that are suited to the environment. In modern terms, we would say that the genetic makeup of the population has changed over time, and that is one way to define evolution. Evolution leaves observable signs. There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.

What is the relationship between a gene and an operon.
Answer:
An operon is a segment of DNA containing a cluster of genes, which are all under the control of a single promoter and the same regulatory elements. The genes in an operon get transcribed together into a single mRNA strand and therefore undergo the same transcriptional regulation.

differentiate the types of muscle- skeletal, cardiac, smooth
Answer:
Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
Explanation:
Answer:
cardiac muscles perform involuntary muscular movements of the heart, aiding the heart to pump blood throughout the body, while skeletal muscles perform voluntary muscular movements of bones, aiding physical movements of the body such as walking, running, and writing and smooth muscles perform an involuntary muscular movements of internal organs, aiding functions of the body such as digestion, urination, and breathing.
Is the "Kingdom" level more specific or less specific then the "Domain" level?
Answer:
It is less specific. I know it can be hard to memorize all of the taxa but I just try to use a mnemonic (which I included below)
Explanation:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
*Remember that in order to give an animal a scientific name we use the genus and species. Scientific names are always italicized and the Genus will be capitalized while the species is lowercase. The genus comes first.
Here is a mnemonic to help memorize the 7 taxa (Taxa is just the fancy word for each group in our classification system) Daring Kings Play Cards On Funny Green Stools.

Why do so some birds addict to smoke?
Nicotine is absorbed easily through the skin and feathers of birds. The smoke emitted from cigarettes will release nicotine into the air and that nicotine will settle on surfaces. These surfaces include your bird’s cage, bowls, toys and the bird itself. When a bird has nicotine land on their skin from secondhand smoke they will many times pick at their feathers or bite at their feet. Some will bite at themselves to the point that they create open wounds.
Respiratory infections and lung cancers are also a concern for birds kept in an environment where secondhand smoke is prevalent. Pneumonia is a very serious condition in domesticated birds and can lead to death.

7. Discuss the practical and theoretical differences between an interval training program used to improve the ATP-PC system and a program designed to improve the ATP production via glycolysis.
The ATP-phosphocreatine (PC) system is more suitable in conditions of high energy expenditure, whereas glycolysis is a step during cellular respiration.
What is cellular respiration?Cellular respiration is a chemical process by which aerobic cells generate energy in the form of ATP by using foods as a source of energy in presence of oxygen.
During cellular respiration, glycolysis (glycolytic pathway) is the first step for ATP production.
The ATP-PC system is anaerobic, works in hypoxia conditions (oxygen absence), and is faster to provide energy than cellular respiration.
However, the ATP-PC system is energetically less efficient than cellular respiration in terms of the number of ATP molecules produced per unit of glucose.

Algae are small photosynthetic organisms found in aquatic ecosystems. Their cells produce a kind of oil. Scientists learned how to extract the oil to create fuel, which can be used in place of fossil fuels. Scientists think algae can produce 60 times more oil per acre than plants, like corn, that are commonly used to produce biofuel.
To produce algae oil, very large ponds were built for growing algae. However, scientists soon made two discoveries.
As the algae grew, it formed layers at the pond surface. These layers crowded and shaded one another.
Many insects and other consumers frequently entered the ponds.
Based on the two discoveries, what would likely be a problem for algae oil production?
A.
Crowding reduces access to food, so it makes algae less able to take in sugar and produce oil.
B.
Insects feed on algae, so all of the energy stored in algae oil is converted back into light energy.
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment.
D.
Shading reduces access to sunlight, so algae produce less sugar and are less able to store energy.
Answer:
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment
