Answer:
Cell membranes are composed of proteins and lipids. Since they are made up of mostly lipids, only certain substances can move through. Phospholipids are the most abundant type of lipid found in the membrane. Phospholipids are made up of two layers, the outer and inner layers.
So, a cell membrane is mostly made of phospholipids and proteins.
A cell membrane is mostly made of phospholipids and protein and they have their specific functions.
Cell membrane comprises of phosholipid bilayer which lipid and cholesterol and is useful in the selective passage of molecules in and out of the cell of the organism.
The proteins however are useful in terms of acting based on chemical
signals provided within the cell and in the transportation of materials

Snow slides down a mountain in an avalanche. Where would the snow have the
most potential energy?
Answer:
At the top of the mountain
Explanation:
The snow will have the most potential energy at the top of the mountain. Potential energy is the energy at rest of a body. It is a function of the mass, acceleration due to gravity and height of the body.
P.E = mgh
Since at the top of the mountain, we have the highest elevation. So, we expect that at the peak of the mountain the potential energy will be highest here.

Many processes occur in the digestive system .which process is best classified as a physical change
Answer:
This question lacks options, the options are:
A) Saliva converting the starch molecules in crackers into simple sugars
B) Digestive enzymes breaking down proteins into smaller fragments
C) bacteria converting lactose into simple sugars in the intestines
D) teeth grinding an almond into smaller pieces in the mouth
The answer is D
Explanation:
A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.
In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.
Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.
Answer: D
Explanation: because you are breaking down food in a physical change

Answer: cold, highly populated areas
Explanation: flu is a great example of an airborne disease. flu is spread mainly at parties, stores, and big cities. Diseases like these like cold air, as warmer air kills it. This is why you should wash your hands with warm water.
hope this helps! Please let me know<3
Answer:
Many common infections can spread by airborne transmission at least in some cases, including but not limited to: CO.VID-19; measles morbillivirus, chickenpox virus; Mycobacterium tuberculosis, influenza virus, enterovirus, norovirus, and less commonly coronavirus, adenovirus, and possibly respiratory syncytial virus.
Air-borne diseases are favoured in various ways like if the pollution rate is high then the spreading of air-borne diseases will be high.
The air-borne disease can also be spread in case if a sick person sneezes or coughs the microbes that cause the disease will be spread in the air and could be inhaled by healthy people which will make them sick.

what are the similarities and differences between water and glucose?
Answer:
See the answer below
Explanation:
Both water and glucose contain hydrogen and oxygen. However, glucose has carbon in addition to the two elements. A molecule of glucose has 6 carbon, 12 hydrogen, and 6 oxygen atoms while a molecule of water has just 2 atoms of hydrogen and one atom of oxygen.
Both glucose and water are polar molecules.
Water is liquid at room temperature while glucose is a solid at room temperature.
In terms of structures, the overall structure of water is bent while that of glucose may be alpha or beta 6 carbon ring structure.

each of my nucleotides includes a phosphate sugar and base am i dna or rna
Nucleotides are defined as the building blocks of DNA and RNA. These are the genetic material found in every living cell. The nucleotides are made up of sugar, a phosphate group, and nitrogenous bases.
The molecules like DNA and RNA have some of the building blocks same. The pentose sugar and nitrogenous bases. The molecule when composed of sugar molecules and nitrogenous bases are termed as a nucleoside.
The addition of the phosphate group to a nucleoside forms the nucleotide.
RNA is composed of nitrogenous bases (adenine, cytosine, uracil, and guanaine), pentose sugar (ribose), and a phosphate group.
DNA is composed of nitrogenous bases (adenine, cytosine, thymine, and guanaine), pentose sugar (deoxyribose), and a phosphate group.
Thus, DNA and RNA are nucleosides consisting of nitrogenous bases (purines and pyrimidines) and sugar groups.
Therefore, the correct answer is the molecule can be DNA or RNA.
