Describe the property of water that is indicated by the data. How is this property explained by the structure of water molecules and the bonds between them?
Answers
Water's cohesive property, which makes it stick together in drops, is due to its molecular structure that facilitates hydrogen bonding. The polarity of water molecules leads to the formation of hydrogen bonds, which makes water a structured liquid with high surface tension.
The Property of Cohesion in Water
The property of water indicated by the data is its cohesive nature. Water molecules exhibit a strong tendency to stick together, forming drops rather than existing as separate molecules. This behavior is most visible when observing water dripping from a leaky faucet or accumulating in dew drops.
The cohesive property of water is explained by the molecular structure of water, or H₂O. Each water molecule consists of one oxygen atom covalently bonded to two hydrogen atoms, creating a polar molecule with a partial negative charge on the oxygen and partial positive charges on the hydrogens. This polarity allows water molecules to form hydrogen bonds with each other, where the oxygen of one water molecule attracts the hydrogen of another. These bonds create a network that holds the molecules together, contributing to water's high surface tension and its ability to form drops.
Hydrogen Bonding in Water
Hydrogen bonding is the molecular structural feature responsible for many of water's unusual properties. The bond is relatively weak on its own, but when many hydrogen bonds form between water molecules, they collectively create a stable, structured liquid. This extensive hydrogen bonding is what gives water a high boiling point, high heat capacity, and the ability to dissolve numerous substances, which is why water is often called the 'universal solvent'.
In essence, the structure of water molecules and the network of hydrogen bonds between them are the keys to understanding why water behaves in such distinctive ways compared to other molecules of similar size.

why do some molecules need help moving across a cell membrane in the form of energy
Answers
Answer:
Because that molecules are moving against a concentration gradient and they can not freely pass trough the membrane.
Explanation:
Cell membranes are constituded by lipid bilayers with an hidrophobic nature. This means that water or molecules disolved in water can not freely pass the membrane. All these molecules are in a bigger concentration outside the cell, so the transport inside cells will be against a concentration gradient and this type of transport requieres energy.
Some molecules need help to move through the cell membrane in the form of energy because transport occurs against the concentration gradient and, therefore, the molecules require an energy supply.
The transport in cells is carried out through their membrane by different mechanisms, in order to enter nutrients and eliminate waste.
Many molecules can pass through the membrane without difficulty, but there are others that, due to their composition, it is not easy to do so and therefore require an energy supply.
For this there is the active transport of molecules, it requires energy to be carried out, since it is a type of movement where molecules go against the concentration gradient (from a place of lower concentration to one of higher concentration) and it is carried out by means of pumps, a clear example is the pump that transports sodium and potassium.
If the cells were unable to carry out this transport, the organism would not carry out its vital activities.
Therefore, we can conclude that some molecules need energy to move across a cell membrane because they go against the concentration gradient.

Sugars do not function only in the production and storage of cellular energy. They also can be used to make mechanical supports. Both plant and fungal cells gain structural support from cell walls composed of carbohydrate polymers. Compare the chemical component(s) of these cell walls.
A) Like plant cells, fungal cells possess a clews composed of cellulose.
B) Plant cell walls are composed of cellulose while fungal cell walls are composed of chitin.
C) Plant cell walls are composed of starch while fungal cell walls are composed of cellulose.
D) Plant cell walls are composed of cellulose while fungal cell walls are composed of a mixture of cellulose, starch and chitin.
Answers
Answer: B) Plant cell walls are composed of cellulose while fungal cell walls are composed of chitin.
Explanation: Plant cell walls are composed of cellulose while fungal cell walls are composed of chitin./b> Both compounds are carbohydrate polymers, but are composed of different monomers. The cellulose of plant cell walls is a polysaccharide of glucose. The chitin of insect exoskeletons and fungal cell walls, is also a polysaccharide: a linear polymer of a sugar derivative called N-acetylglucosamine.
Plant cell walls are composed primarily of a carbohydrate polymer called cellulose, providing structural support. Conversely, fungal cell walls are made primarily of a unique carbohydrate polymer called chitin. Despite both providing structural support, they are composed of different carbohydrate polymers.
Explanation:When comparing the chemical components of the cell walls of plants and fungi, B) is the correct option. Plant cell walls are primarily composed of a carbohydrate polymer called cellulose. This material is tough and fibrous, providing plants with the necessary structural support and rigidity.
On the other hand, fungal cell walls are primarily composed of a unique carbohydrate polymer called chitin. While it similarly provides structural support, chitin is a different substance entirely with its own unique properties. Therefore, despite both serving a similar purpose, plant and fungal cell walls are composed of different carbohydrate polymers: cellulose and chitin respectively.

Explanation:
All living organisms contain carbon atoms.Carbon atoms can bond with many other kinds of atoms to form very stable molecules. This is an important characteristic of carbon therefore it is present in many living organisms. It is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms .This is due to the fact that the carbon atom is just the right size to fit in snuggly as part of very large molecules.
The statement ''Carbon atoms can bond with many other kinds of atoms to form very stable molecules'' is an important characteristic of carbon.
Answer: Option C
Explanation:
Carbon is found in all the living organisms right from the extinct dinosaurs to the existing living organisms. It is the most abundantly available material in the whole world. Thus it helps us to identify the living period of fossils by the carbon deposited in it through a process called carbon dating.
Living things get carbon from the carbon dioxide dissolved in the atmosphere. Carbon has the tendency to bond with many other kinds of atoms to form a very stable molecule like graphite, diamond etc. Carbon is the base of the entire bio-chemistry.
how is physiology of a bone related to its anatomy
Answers
Bone physiology is intimately connected to its anatomy, as the structure of bones dictates their function in body support, protection, and movement. The continuous remodeling of bone as well as specific anatomical features, like the arrangement of hand bones, exemplify the form-function relationship.
Explanation:The physiology of a bone is deeply related to its anatomy because the physical structure of bone (its anatomy) determines how it functions (its physiology). Bones are not inert structures; they are dynamic and continuously remodeled throughout one's life to adapt to various stresses. Bone remodeling is a physiological process where approximately 10% of bone mass is turned over annually. This ongoing process helps the bone maintain its strength and adapt to the mechanical load it is subjected to.
Bone's structure is a composite of organic collagen and inorganic hydroxyapatite that provides the necessary strength to support body weight. The outer portion, called cortical bone, is dense, while the inner part, known as cancellous bone, is spongy. This specialized structure enables bones to perform their physiological functions, supporting body structures, protecting organs, and facilitating movement in conjunction with muscles.
Similarly, the anatomy of the human hand, with its unique arrangement of bones, reveals a close relationship with its function; the thumb's opposition to the four fingers allows for complex manipulations like pinching, grasping, and typing. Understanding the anatomy and physiology together enhances comprehension of how form and function are correlated in living organisms.

C. They have membranes composed of many carbohydrates.
D. They have double membranes, with one membrane enclosed within the other.
Answers
Answer:
The answer is B. They have highly folded membranes.
Explanation:
A highly folded structure is advantageous for microscopic organelles such as the mitochondria and the endoplasmic reticulum. These organelles need to produce high amounts of ATP and proteins in a day, respectively.
For the endoplasmic reticulum, with ribosomes attached, it is responsible for the manufacturing, packaging, and transport of specific proteins. Same goes for the mitochondria, which is responsible for energy production and respiration. These processes are so demanding that in order to be more efficient in being productive, the highly folded membranes provide a wider and better surface area for synthesis of proteins or ATP, despite the size of these organelles.
