Structural organization of life is the existence of life from a single celled organisms to multi cellular organism with complex forms that perform different functions.
The structural organization found in multicellular organisms from the lowest to the highest in hierarchy are described below.
The organelle: This is the non-living part of a cell that interacts to form a cell. The cell level: This is the basic functional and structural unit of life.The tissue level: This is the collection of cells that are similar in structure and perform similar function.The organ level: This is the collection of different tissue that perform different functions. Examples are kidney, heart, liver.The system: This is the collection of different organs that perform a particular function. Examples of system include circulatory system and excretory system.Learn more here:

Carbohydrates are a class of chemical compounds composed of carbon, hydrogen, and oxygen in 1:2:1 ratio, respectively.Cells are made of organelles, specialized structures that each perform specific functions that help the cell maintain homeostasis. This is much like the body systems work together to help the body maintain homeostasis. Consider the function of the nervous system. Which organelle is most similar in function?
Answer:
Organelles serve specific functions to keep a cell alive.
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Why is water called universal solvent?
Water is called a universal solvent because it can act as a solvent in many
different solutions.
Water comprises of the elements Hydrogen and Oxygen and is very
important which is why it is a compound which is commonly present
everywhere across the earth.
Water is a solvent and has the ability to dissolve different types of solutes
and solutions as a result of its high polarity. The substances must however
be polar too in order for this to take place as water doesn't act as a solvent in
non-polar substances.

5X eyepiece with a 100x objective
15x eyepiece with a 4x objective
10x eyepiece with a 100x objective
10x eyepiece with a 10x objective
Answer:The telescope’s focal length (for example, 1200mm) The eyepiece’s focal length (for example, 25mm) To find the magnification, we’ll simply divide the numbers: 1200mm / 25mm = 48x magnification

Explain why the a single loop circulatory system is able to supply raw materials to cells as fast as the double – loop circulatory system.
Answer:
In the case of single circulatory systems, e.g. as in fish, the heart receives deoxygenated blood (also described as 'oxygen-poor blood') into the atrium of the heart and pumps it through the ventricle of the heart so that it continues onwards to the gills.

how are enzymes, proteins, and amino acids related, and what is their role in a viral take over?
Answer:
Amino acids are building blocks to proteins, and the combination and order of them determines what protein is actually being built. Then enzymes are a type of protein which facilitates or catalyses a process, such as the breaking down of molecules in your food. In a viral takeover, the virus uses your body's ribosomes to create viral proteins (consisting of amino acids). Viral enzymes actualy facilitate this by inserting viral DNA into the hostcell's DNA.

Macromolecules which are both hydrophobic and hydrophilic and are a major component of cell membranes are –
Answer:
Phospholipids
Explanation:
The plasma membrane's fundamental fabric is made up of a bilayer of proteins that are organised in a bilayer. Because they are amphipathic, which means they have both hydrophilic and hydrophobic areas, they are well-suited for this job.

Which of these correctly demonstrates the biomolecule with its function?
A)
steroids; separate the cytoplasm from the environment
B)
waxes, prevents water loss and repels water
c)
triglycerides; make up sex hormones
D)
phospholipids, store energy
Answer:
B) Waxes, prevents water loss and repels water
Explanation:
Waxes, steroids, phospholipids, and triglycerides are types of lipids. All of them are made of Hydrocarbon chains that are hydrophobic.
Triglycerides (fats) - Storage molecules for the body's energy
Steroids - Sex hormones and cholesterol
Phospholipids - Cell membrane (Separates cytoplasm from the environment)
Therefore, Answer choice B) Waxes, prevents water loss, and repels water, is the only answer that correctly matches with the provided answers.
describe the role of the liver in the assimilation of amino acids by converting them to proteins.
Explanation:
The liver is important in assimilation. For example, it converts glucose into glycogen (a complex carbohydrate used for storage) and amino acids into proteins. ... This is the removal of the nitrogen-containing part of amino acids, to form urea, followed by the release of energy from the remainder of the amino acid.
The deamination process involves the liver. This involves the release of energy from the remaining amino acid after the nitrogen-containing portion of the amino acid is removed to generate urea.
What is assimilation of amino acids in liver?Assimilation is the transport of molecules from digested food into the body's cells, where they are utilized and eventually become a part of the cells.
Extra glucose in the blood that reaches the liver is either broken down through respiration to produce energy for other uses or turned into glycogen (animal starch) for storage.
The complex proteins and carbs are broken down into glucose and amino acids during absorption. As a result, glucose is used in respiration while amino acids are obtained for the creation of new proteins.
Therefore, the role of the liver in the assimilation of amino acids by converting them to proteins.
