What are the characteristics of saturated fatty acids? Check all that apply. Each carbon atom in the carboxylic acid chain is bonded to at least two hydrogen atoms. At least one double bond links carbon atoms in the carboxylic acid chain. The lipid is a straight chain. The lipid is a liquid at room temperature. The lipid is a solid at room temperature.
Each carbon atom in the carboxylic acid chain is bonded to at least two hydrogen atoms and The lipid is a solid at room temperature are the characteristics of saturated fatty acids.
Where are saturated fatty acids found?
Although plant foods like coconut, coconut oil, palm oil, and palm kernel oil are high in saturated fats, saturated fat is mostly found in animal meals. However, replacing saturated fat with refined carbs will probably negate the benefits of cutting back on saturated fat.
No carbon-to-carbon double bonds can be found in saturated fatty acids, while one can be found in monounsaturated fatty acids and two or more can be found in polyunsaturated fatty acids. Since there are enough hydrogen atoms in the saturated fatty acid molecule, every carbon atom is single-bonded. A carbon atom at the end of a chain of saturated fatty acids is doubly linked to an oxygen atom and singly bonded to a hydroxyl group.

The woolly mammoth was a relative of modern elephants that lived in the cold northern parts of the world less than five million years ago. Mammoths in warmer parts of the world lacked the warm, shaggy fur the woolly mammoth developed.
Which of the following sentences best describes how natural selection resulted in the woolly mammoth?
Mammoths stopped shedding. Eventually, they lost the ability to shed fur.
B.
Cold climates triggered the growth of thick, warm fur on mammoths.
C.
Mammoths used their hair follicles to grow fur more often, resulting in stronger hair follicles.
D.
Mammoths with thicker fur were more successful at surviving and reproducing in cold climates.
Identify the by-products of the atmosphere. Briefly state where and how it is formed
Answer:
Earth’s original atmosphere was probably just hydrogen and helium, because these were the main gases in the dusty, gassy disk around the Sun from which the planets formed. The Earth and its atmosphere were very hot. Molecules of hydrogen and helium move really fast, especially when warm. Actually, they moved so fast they eventually all escaped Earth's gravity and drifted off into space.
Earth’s “second atmosphere” came from Earth itself. There were lots of volcanoes, many more than today, because Earth’s crust was still forming. The volcanoes released:
1) steam (H2O, with two hydrogen atoms and one oxygen atom),
2) carbon dioxide (CO2, with one carbon atoms and two oxygen atoms),
3) ammonia (NH3, with one nitrogen atom and three hydrogen atoms).
Much of the CO2 dissolved into the oceans. Eventually, a simple form of bacteria developed that could live on energy from the Sun and carbon dioxide in the water, producing oxygen as a waste product. Thus, oxygen began to build up in the atmosphere, while the carbon dioxide levels continued to drop. Meanwhile, the ammonia molecules in the atmosphere were broken apart by sunlight, leaving nitrogen and hydrogen. The hydrogen, being the lightest element, rose to the top of the atmosphere and much of it eventually drifted off into space.
Now we have Earth’s “third atmosphere,” the one we all know and love—an atmosphere containing enough oxygen for animals, including ourselves, to evolve.
So plants and some bacteria use carbon dioxide and give off oxygen, and animals use oxygen and give off carbon-dioxide—how convenient! The atmosphere upon which life depends was created by life itself.

Watch the video linked here: Then, respond to the following questions: a. What are allergies? What is the relationship between allergies and the immune system? allergies b. How does a medicine like Benadryl (a medicine taken to suppress allergy symptoms) affect the immune system? c. How would a medicine like Benadryl affect a person if the allergen were a dangerous pathogen? d. Do you have any allergies? According to the video, what might we infer about your childhood exposure to pathogens based on your current allergies?
Answer:
A. Allergies make a person react to substances in the environment that are harmless to most people but are harmless to the person reacting. Allergic reactions begin in your immune system. When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may overreact by producing antibodies that "attack" the allergen.
B. This medication works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.
C. It can cause a drying effect mouth and eyes, sedation, and sleepiness. However, it can impair innate immune responses to bacteria, and that these drugs should be used with caution in patients with severe bacterial infections.

What are homologous structures of the swamp wallaby, common long-nosed armadillo, bearded pig, northern elephant seal and rock cavy.
Answer:
When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.
Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.

How is efficiency related to systems?
Answer:
The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.
