The answer is A I believe.
An atom will usually form either an ionic bond or covalent bond with another atom but not both.
Ionic bonds are the kind of bonds that result when one atom transfers or gives up electrons and another atom receives them and adds them to its own energy shells.
An example is sodium metal and chlorine gas. Sodium gives up two of its electrons and Chlorine receives them and the two elements form an ionic bond to create sodium chloride, a new compound.
Covalent bonds are the kind of bonds formed when two atoms decide to share electrons. No atom gives up any electrons and neither does the other atom receive any. An example is water. An oxygen atom shares two of its electrons with two hydrogen atoms to form a molecule of water (H2O).
Answer:
Polypeptide F. building blocks of proteins
Answer: Option B) allosteric activation
Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation
Explanation:
Some enzymes have more than one active site. The other site(s) is called allosteric site.
In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.
ATP + H2O ---> ADP + Pi + free energy
Answer:
The correct answer is -
differences: color, brightness, temperature, size, and mass
similarities: They are balls of gas, mostly hydrogen and helium
Explanation:
Stars look mostly the same from anywhere or any place and tough to differentiate or distinguish one from another. Star can be different on the various ground even they look similar from far away.
Stars can be of various colors from red to blue and brightness can be different as well, color depends on temperature, and brightness depends on the size of the star.
Stars are grouped by the size that ranges from dwarf to supergiant. The temperature of the stars also varies which affects the color and brightness as well.
Stars are the big balls of gases composed of mainly helium and hydrogen all are always under a nuclear reaction.
