Why is there Cholesterol in your cell membrane?
Answer:
Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

which two products are bromelain likely to produce when breaking down proteins
amino acids
fatty acid
monosaccharides
nucleic acid
polypeptides
disaccharides
The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

A. Lipid synthesis
B. Protein synthesis
C. Detoxification
D. Ion storage
Answer: B
Explanation:
Discuss how the properties of water help Earth support life.
Water Property:
Importance to Life:
Polar molecule:
Hydrogen bonding:
Cohesion:
Adhesion:
Surface Tension:
Temperature Moderation:
Low density of Ice:
Universal solvent:
Answer:
One of water’s important properties is that it is composed of polar molecules. The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen. Thus, it is more likely that a shared electron would be found near the oxygen nucleus than the hydrogen nucleus. Since water is a nonlinear, or bent, molecule, the difference in electronegativities between the oxygen and hydrogen atoms generates the partial negative charge near the oxygen and partial positive charges near both hydrogens.
Explanation:
As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids. A polar substance that interacts readily with or dissolves in water is referred to as hydrophilic (hydro- = “water”; -philic = “loving”). In contrast, nonpolar molecules, such as oils and fats, do not interact well with water, as shown in. These molecules separate from it rather than dissolve in it, as we see in salad dressings containing oil and vinegar (an acidic water solution). These nonpolar compounds are called hydrophobic (hydro- = “water”; -phobic = “fearing”).
The properties of water help Earth support life helps in various ways. Most of the role of the water in supporting life is because of its molecular structure which causes its specific properties.
Water is a simple molecule made of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom.
Polar molecule: The charge difference between the positive charge on one side and the negative charge on the other side form an asymmetrical molecule called a polar molecule that interacts with different molecules. Hydrogen bonding: Due to hydrogen bonding water has various life-supporting properties by the interaction of various molecules. Cohesion: water molecules attract other water molecules in a property called cohesion that plants take up water at their roots and it affects boiling point regulates body temperature of animals. Adhesion: Attraction to other molecules called adhesion that helps in binding with different types of molecules Surface Tension: surface tension of water is similar to the cohesion Temperature Moderation: water's heat capacity or specific heat prevent immediate temperature changes Low density of Ice: helps ice to flow on water not to immerse. Therefore life under the ice can be maintained. Universal solvent: makes water dissolve with other molecules and make a life-sustaining force that helps cells transport and use substances like oxygen or nutrientsThus, water is essential for supporting life and survival.

How does surface area describe a cell?
Answer:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
