Which substance is important to the structure of the plasma membrane because it helps the membrane to keep its shape and fluid qualities?
Answer: Phospholipids
Explanation:
Phospholipids are arranged in a bilayer. This makes up the basic fabric of the plasma membrane.
Cholesterol molecules are distributed preferentially between membrane phospholipids. This helps to keep cell membranes from stiffening by preventing phospholipids from being packed too closely around each other.
What is plasma membrane?The plasma membrane, also known as the cell membrane, is the membrane found in all cells that differentiates the cell's interior from its surroundings.
A cell wall is connected to the plasma membrane on the outside of bacterial and plant cells.
Membrane biogenesis is the process by which plasma membranes form. Proteins as well as lipids are created first in the rough endoplasmic reticulum and then in the smooth endoplasmic reticulum. These are then delivered to the Golgi complex for adjustment.
The basic material of the plasma membrane is composed of phospholipids arranged in a bilayer.
They are amphipathic, which means they have both hydrophilic and hydrophobic regions, making them ideal for this role.
Thus, phospholipids helps the membrane to keep its shape and fluid qualities.

Why do you think carbon has an entire branch of
chemistry devoted to its study?
Answer:
Carbon has the ability to form 4 bonds with surrounding atoms. It can also form branches, which can be tens of hundreds of carbons long. There are millions of variations of carbon-containing compounds, so a whole branch of chemistry is needed in order to comprehend them.

Tay Sachs is a disease caused by a mutation in a gene that codes for an enzyme used to break down complex molecules. Patients that have Tay Sachs accumulate excessive fat in brain cells and nerve cells. Normal functioning of this cell structure results in the digestion and removal of harmful fat accumulations, old cell parts, and invaders. Due to a mutation, the enzyme needed to remove fat accumulations does not function. Based on this information, what cellular structure is not functioning properly?
Answer:
Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease is Lysosomes
Explanation:
LYSOSOMES -: In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.
TAY SACHS DISEASE -: The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.
Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.
Hence , the answer is lysosomes .

Answer:
all multicellular, make their own food - plantsall multicellular, eat other organisms - animalsmostly unicellular, some make there own food. others consume their food - protistsmostly multicellular, eat dead or decaying organisms - fungiExplanation:
All plants and animals are multicellular organisms. Plants are autotrophs, meaning they can make their own food (usually by photosynthesis). In contrast, animals rely on other organisms as a food source (are heterotrophs)
Fungi and protists are more variable. Protists are mostly small unicellular organisms, some perform photosynthesis to make their own food, others eat other organisms.
Fungi usually consume dead or decaying matter (decomposers)

Which of the following are the large molecules that are broken down into smaller molecules during digestion?
Answer:
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.
Explanation:
Fats, proteins, and carbohydrates are macromolecules that are broken down into smaller molecules during digestion.
What is digestion?The term "digestion" describes the process by which food is broken down into smaller pieces that can be absorbed into the bloodstream.
The breakdown of food into smaller bits, known as mechanical digestion, takes place in the mouth. Chemical digestion, on the other hand, takes place in the gastrointestinal tract when the meal is broken down into small molecules by digestive enzymes. Digestion begins from the buccal cavity.
Macromolecules such as fats, carbohydrates, and proteins, are broken down into their monomeric form. Thus, this four are the large molecules broken down into smaller molecules during digestion.

Density involves the amount of a material in a certain volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together. Water has solid and liquid states that do not follow these predictions of density in the phases of matter.
What does that mean about the densities of the phases of water?
The solid state is the most dense, followed by the liquid state, then the gas state.
The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state.
