A structure that looks the same and does the same job but was not present in a common ancestor is termed:______.
Answers
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 equations are used to calculate the velocity of a wave?
Answers
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)
(e) Describe the role a non-competitive inhibitor would play in the ability of enolase to perform
properly.
Answers
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.

How does weathering affect Earth's surface?
Answers
Answer:
Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock. An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger.
Explanation:
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Explanation:
Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.

Haploid cells are produced during meiosis.
Identical haploid daughter cells are produced from diploid parent cell.This process is required to produce egg and sperm cells for s exual reproduction.What is meiosis?Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for s exual reproduction.Cell division occurs twice during meiosis, one starting cell can produce four gametes.In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.To know more about meiosis here

Answers
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).
Answers
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.

Answers
Answer:
Please find the flowchart attached as an image
Explanation:
DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.
PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

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
Answers
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.

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?
Answers
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.
