heat energy to mechanical energy
Answer:
The best answer to the question: What might be a characteristic features of the phospholipid head groups? Would be: The phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky.
Explanation:
Phospholipids are the main molecules in biomembranes. Because of their importance to cell membrane formation, phospholipids are very characteristic molecules that have two sides: one polar and hydrophilic, and one non-polar and hydrophobic. The hydrophilic side is really vital, as biomembranes, like cell membranes, are suspended in water, and therefore need to interact with it. But these phospholipids form a structure called a bilayer, meaning, it forms a sort of highly organized lattice (called a leaflet), that has two hydrophilic sides (where the heads of the phospholipids lie) and a middle that is hydrophobic (where the tails are). The perfect interaction of phospholipids with water comes from their unique polar charges in their phosphate groups, which are present in the head side (hydrophilic side) and which form ionic and hydrogen bonds with each other and water. This characteristic provides stability to the structure and permits it to carry out its function with both the outer and inner environments of cells.
Answer:

Explanation:
Answer:
The correct answer would be - strontium, magnesium, beryllium.
Explanation:
As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.
For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.
The first conditioning is the classical conditioning and it can be explained on an example of a dog that is producing saliva when it knows that it will be fed.
the second kind of conditioning is the operant conditioning. An example of an operant conditioning is a dog learning to open a box after it witnessed a ball being placed in it.
