The Channichthyidae fish, also known as the
crocodile ice fish, lives in the Southern Ocean
around Antarctica. These waters are known to
maintain extremely low temperatures all year,
ranging from approximately 28°F to 35°F. These fish
have adaptations that allow them to live in cold, low
oxygen waters. (a) If you were to examine the
membrane lipid composition of cells from the
Channichthyidae fish identify what you would
expect to find. (b) Justify why you might find what
you identified in part (a).
A) If you were to examine the membrane lipid composition of cells from the Channichthyidae fish, what you would expect to find is glycoprotein,zona pellucida protein and a less number of haemoglobin that is found in this type of fish.
B) Justification of why you might find what was identified in part (A) is because;
Glycoprotein contains antifreeze compounds,these antifreeze compounds are what provide resistance to freezing of their hypoosmotic tissues by the subzero environment.
If we analyzed the lipid composition of these fish, we could find glycoproteins.
We can arrive at this answer because:
Glycoproteins are formed by a chain of oligosaccharides, linked to a chain of polypeptides, which are side chain lipids.These glycoproteins have different functions in the body.One of the most important functions is keeping the heat.This function allows heat to remain longer in an organism and heat loss to be slower.In this case, the glycoprotein is an essential molecule in the organism of living beings that live in environments with very low temperatures, such as fish Channichthyidae.

(e) Describe the role a non-competitive inhibitor would play in the ability of enolase to perform
properly.
Answer:
it would not allow enolase to perform properly because it will bind to it and change its shape not allowing 2-phosphoglycerate to bind to it and convert to phosphoenolpyruvate. this is because it is non-competitive which means there is no way that the molecule could bind to the enzyme.

Which of the following questions would BEST
determine whether a plant is undergoing the
Calvin cycle?
A. Is NADPH being produced?
B. Is oxygen being produced?
C. Is glucose being produced?
D. Is ATP being produced?
Answer:
C
Explanation:
Glucose is the end result of the calvin cycle. It is not Oxygen, NADPH, or ATP because those are produced in the light reactions.
Is glucose being produced? is the question which will best determine
whether a plant is undergoing the Calvin cycle.
The Calvin cycle is known s the light independent or dark reaction which
takes place during the process of photosynthesis by plants. The final
product for this cycle is Glucose.
Other compounds such as NADPH, ATP and oxygen are all formed during
the light dependent reactions which is why asking if glucose is produced is
the most appropriate choice.

Which equations are used to calculate the velocity of a wave?
Answer:
The Wave Equation
Multiplying the wave's frequency by its wavelength, which is its physical length, yields the velocity of the wave.
Explanation:
Answer:
Just v = f × λ
v is the wavespeed in m/s, f is the frequency (Hz) and λ is the wavelength (m)
T/F Osmosis and diffusion are both examples of passive transport.
A.True
B.False
Both osmosis and diffusion are passive transport processes, meaning that no additional energy is needed for them to take place. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
The given statement "Osmosis and diffusion are both examples of passive transport" is True.
Passive membrane transfer methods are the most direct. Passive transport is a phenomena that happens spontaneously and doesn't require the cell to use energy to move. Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration. A concentration gradient is a difference in the concentration of one substance throughout a physical region.Transport that is done passively is called diffusion. Until the concentration is the same across the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration.Based on the gradient of water concentration across the membrane, osmosis is the mechanism by which water diffuses through a semipermeable membrane. Osmosis moves just water across a membrane, and the barrier restricts the diffusion of solutes in the water, whereas diffusion distributes material across membranes and into cells.Learn more about the passive transport with the help of the given link:

5. Some advantages of sexual reproduction include: (select all that apply) *
a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

A structure that looks the same and does the same job but was not present in a common ancestor is termed:______.
Answer:
The correct answer is - analogous.
Explanation:
Analogous structures or organs are the structures with the same look which is developed to perform the same job and not present because inherited by a common ancestor.
These structures are present in unrelated organisms and look the same from outside and perform the same action for example wings of bat and birds look and perform the same action but not inherited from a common ancestor.

Which of the following would a lipid most likely do in the body?
А. provide quick energy for exercise
B. store genetic information
С. build muscle tissue
D. store energy for later use
Answer:
D
Explanation:
Lipids have a carboxyl group at one end, a methane group at the other, and a long hydrocarbon chain in between. This structure makes it suitable for long-term energy storage. Quick energy is usually provided by carbohydrates. Nucleic acids store genetic information, and muscle tissue is made up of muscle cells.
The most likely function of a lipid in the body is the storage of energy for later use. Choice D.
Although, lipids are a good source of energy with about 9kcal of energy supplied per gram.
Lipid metabolism to provide quick energy is quite a slow process as opposed to carbohydrates which provide quick energy for exercise and other tasks.
Nucleic acids are responsible for storing genetic information.
Muscle tissues are built by muscle cells.
As lipids are a high energy yielding source, lipids are responsible for storing energy for later use.
